Recap of the SAI circuit
 

deleted

And the purpose of the circuit is?

If you have issues with Secondary Air Injection ports being blocked or you want to remove the entire SAI system from your '96 - '98. '95s have the system but the ECU does not check if the system is working correctly.

The blocked ports issue shows up as OBD errors:

P0410 - Secondary Air Injection System: Malfunction
P1411 - Manufacturer specific code

This one is a keeper! Thanks.

This looks interesting. I'm curious if you need to do this before a CEL is tripped or if it can be done afterwards, clear the CEL with my OBDII code reader and then still get through emissions.

It can be done before or after. Of course if done after tripping the CEL, the error must be cleared and the registers retested with the drive procedure to pass smog.

Interesting solution.

Is there a way through SW to just 'ignore' this fault code so it doesn't register at all? There is no real drivability concern, just your CATs are not getting as hot as they could if they were getting more fresh air at startup. I vaguely remember back from my BMW days that there seemed to be a SW fix for some of those guys who also suffered from clogged SAI issues. Some companies offered it as part of a chip tune. I think they called it a "Carbon Ignore" or something like that. Granted, my coding knowledge is very limited, but it seems reasonable that you could edit it to just ignore a particular code. Of course there is the whole 'legality' of such a solution, but if it is for 'off road use only', maybe it will be OK. :)

I have yet to see a software solution in person. There was a rennlister who posted a friend paid around $1000 to reprogram the ECU to ignore the fault. There is a company called TurboWerx saying for a year that they were coming out with a ECU add-on to ignore the error for $400. This circuit was $10 which is for "testing and educational only". ;)

I certainly think this HW solution has merit. Hard to say no to $10.

Still, it would seem there should be some kind of SW fix possible. Granted, I doubt it would be $10, but it would be totally stealth as long as it didn't throw anything else off. Given a lot of folks go the chip route anyway, adding this 'SAI ignore program' while you're at it seems reasonable.

Please forgive my ignorance here, but don't ROW cars ignore the SAI since it is not used? What if someone swapped in one of those ECUs? A lot of the OBDII codes are generic so it seems plausible on the surface although i'm sure there is some devil in the details. On that note, what are the major differences between a ROW and US ECU? Perhaps some different level of tune due to the octane ratings? What else constitutes the difference? Would a US car run if a ROW ECU was swapped in and nothing else changed?

No SAI on ROW cars. No OBDII either :)

Check out the link in my sig if you're interested in the ECU difference between ROW and US.

Cheers,
Joe

Where does the gray wire go? Is it just grounded or does it have to go to wire 3 of one of the O2 sensors?

I grounded the gray wire to the chassis.

"Still, it would seem there should be some kind of SW fix possible."

Not really, without a MAJOR redesign (patch) in the firmware coding,
and not just changing cell entries like the Mickey Mouse so-called tuners
do! This would require a lengthly dis-assembly of the 993 DME ECM
firmware and redesign of OBDII firmware.

Remember, besides the actual test, the cycle flag for the SAI test must
be set or in the end none of the readiness codes (monitors) will be set
to allow an emissions test to begin at the smog station, i.e. readiness
codes ONLY show full completion when all tests have fully completed
successfully.

I got my parts from Jameco and I'm going to see if I can assemble the circuit board. Looks pretty simple. I have had the CEL for about 2 years due to the SAI. Tried cleaning the ports but ran into a corroded manifold. If this works, it will be nice to get rid of that yellow light on the dash. I'll try to remember to post some pictures and updates. I'm a mechanical engineer, not electrical, so I will trust you spark chasers you the components all worked out.

Good luck Mike, let us know how it turns out, Im thinking about doing this myself

If anyone needs electronics help with their prototypes, please feel free to PM me (I've been doing electronics for 40 years)

It would also be a very simple task to design a very quick and inexpensive printed circuit board (probably around $5 + parts) which would make assembly much easier...sort of like an old Heathkit.

please please!

Lewis

If you decide to make the boards, I'd be interested.

Tony

Is there a specific size the PCB should be?
Would an assembled board be better than a bare board/bag of parts? I know some people don't like to solder.

I took a quick look at the schematic and it looks OK, I would perhaps make some minor changes.
(I designed OEM electronics for Porsche, Audi, Mercedes so working on a 12V automotive bus is something you don't forget)

I could probably do something like this on a rainy weekend, send the files out to have boards made (usually 1 week) and assemble a few in my basement electroncis shop.

Lewis,
I would be very interested in purchasing one of these boards for my car, also. Can I give you a "deposit?"
Thanks,
Phil

I would also buy a board. Just so things are clear -- this enables us to physically remove the SAI system from our cars, including the OBDII ones, and never have a problem with getting smogged/CEL's?

That's me! :confused:

A pre-assembled board would be fantastic. Installing it in the car would be piece of cake.

I don't mind doing the PCB layout and soldering/assembling the boards.
I am not looking to make any profit from this, so it would just be cost + shipping.

I will double check with the Admin (Bob) to make sure there are no issues.

That's correct. You would no longer see SAI errors but other CELs unrelated to SAI are still possible which is a good thing.

I would imagine soldered components would be best for most. I'm interested in a couple as well.

One variant I did from the schematic, is the 12v ground wire was connected to the chassis directly instead of the gray O2 sensor lead just to make it more convenient.

I'll take one too, Lewis. Thanks for the offer!

That being said I can see how this easily could turn into a 100+ unit job so if you decide to outsource it I would be more than happy to cover the costs. I'm sure most people here would be too.

Thanks again!

A question on wire termination options.

1. soldered wires, say 12" long, coming off the board
or
2. use screw terminal blocks, allowing you to chose wiring type/length/etc...no soldering required (they are fairly inexpensive), just a screwdriver
Example:
http://search.digikey.com/scripts/dk...name=A98036-ND

It would be the same PCB, in the first case, I simply don't install the terminal block and solder wires instead.

I have sent a PM to the Admin and IB, just to make sure there is no conflict of interest (I am not a RL sponsor and not doing this for a profit... more of a hobby).

Once I hear back, I will likely setup a seperate thread to keep track of who would like the PCB. It will be small enough to be sent via USPS (which should keep costs down)

I'm in for a soldered board. Suggest $10 if Lewis does it for $5 (but only $5 if Larry does the work underground), BTW, Heathkit? Wow, that was awhile ago.

Forgot to add ... Thanks for stepping up on this. Very nice.

Thanks for doing this Lewis. Looks like there is lots of interest.

I would suggest soldered wires coming off the board. That makes it one less step to install and I don't have to think about what kind of wires I want to use. The users who want a very specific wire and length will probably change it anyway.

Are you thinking of providing boards with components installed, just a board, board and kit of parts, or all three variations?

Other posts have brought out concerns of liability if the circuit should cause some problem to their car. You may want to provide a kit of parts with instructions and let the builder accept responsibility. I don' tknow the interface to the ECU and what the possibility is of ECU damage if a short to ground or short to hot should occur.

One for me to please Lewis if you decide to make them.

Please add me to the list for this PCBA.

Bill

Please one for me as well should this move forward. Would be interested in assembled board or with bag of components. Thanks for pursuing this!

I can provide a bare PCB along with a bag of parts (Heathkit style) or an assembled board.

In order to make it easy to solder for the DIY folks, I will design it with all through hole components instead of surface mount ... Old School

Don't want a single $ above and beyond cost + shipping.

Yes, Heathkits. I was the youngest certified Master Builder in Heathkit history. I used to build the kits for the showroom when I was about 10 yrs old.
I could build a kit in 1/3 the time of anyone else and never had an assembly error.
Rather than cash, I was given kits as payment. I still have some Heathkits from the 70's still in boxes, along with a dozen or so assembled units.

Since Larry is dead, I plan on using him for assembly labor :typing:

Lewis, what a great idea. I know you are a whiz at this, and this truly exemplifies the Rennlist Spirit. Well done! I am copying your post as well Flying Low's to the DIY forum. Thanks to you both!

Best,

OK, just heard back from Bob (RL admin) and there are no issues or conflicts with me doing this.

So, this weekend should be schematic capture, library work and PCB layout.

I will ask one of the Mods to stick a thread at the top of this forum to act as a list of who wants one and in what configuration (kit or assembled).

I will source all the components from DigiKey and the PCB from Advanced Circuits, so there will be full visibility into the parts cost.

Lewis

you are a wizard. Please count me in too. Many thanks and what great talent we have on this board

Dave

I want one of these.

down for one as well.

Wow Lewis...incredibly generous of you to do this...I'll definitely be signing up for one... cheers!

What other parts does one need to remove the OBDII SAI system? Aren't there a couple of plugs or something?

I could REALLY use one right now for a '97 M3. The only readiness indicator not set is the SAI and I've replaced the air pump and check valve.

I'll take one for the 993, will post in the order thread when it gets posted.

I'd love one too if you do them.

Thanks a million!

I'll take a kit. Would appreciate any suggestions on how to learn soldering.

Thanks Lewis!!

Despite being responsible for every problem in every early CS, Lewis is great. Take that PCNA!

"does this enables us to physically remove the SAI system from our cars, including the OBDII ones,"

No! All it does is fool/mis-represent what the O2 sensors 'see' when the
SAI air pump turns 'on', i.e. It basically indicates that an adequate amount
of air is reaching the O2 sensors during a cold start-up.

Why does that mean we can't remove the SAI pump and system from our cars? What am I not understanding here?

Count me in for one! Thanks Lewis. I think I still have an old Heathkit voltmeter from about 1970 that my brother built.

Wherever the "formal" list ends up for sign up, I'm on it. Never know when one may need one.

Thank you Lewis!

I don't see why not. My pump is disconnected. The SAI pump relay is still in place to show a load across the relay. I agree this is not a complete OBDII bypass, just the SAI portion.

This is awesome Lewis! Thanks for taking this to the next level.

Please put me down for 1 ea. assembled and 1 ea. kit. TIA! You da man! :bowdown:

p.s.: Still have my Heathkit strobe light and CO meter (analog...nowhere near accurate enough for today's cars.) Built many kits when I was a teenager.

Great post and Rennlist spirit! I don't have any SAI issues, but I will also like to sign up for one please!

What happened with Post #1 that Flying_low posted with the schematics and pictures? I could see it yesterday but it has dissapeared now...

That's weird. If it doesn't re-appear I'll create a web page on my server for the details.

We made a small error and moved the posts in the DIY section.
I will try to fix it now.

Ok fixed.

I would like one too. :cheers:

"Why does that mean we can't remove the SAI pump and system from our cars?"

Yes, you could remove just the pump, but why? When you remove system
components, it no longer looks stock, i.e. A possible future sale or an
overly committed emissions inspector/tester.

I'm signing up for 2 assembled.

Jack

Ah, okay. So what you originally said is not correct. Thanks for clarifying.

I'm also in for two units. Rennlist is a great place... Thanks

I'm in for one. I can compare it to my "home made" version.

I loved those Heathkits!

+1

Count me in too pls.

add another one to the list! I'm in.

wasn't there a thread awhile back about same that was removed as it was possibly not legal especially for states with smog refs....

Problems or Easter Eggs...it's a fine line :evilgrin:

+1
I sent you a pm earlier... please count me in for one on the first batch !

thanks !...and....very cool.

Lewis,
Are you looking at doing surface mount (smaller) or through-hole parts? What CAD are you using for the layout, and could you release the layout files (Gerbers?) for the PCB when your done so others can make more later if needed?

Thanks,
Aaron

SAI
 

Please add me to the list.

Thanks

I was going to use old school through hole parts, simply because it makes it easier for DIY soldering.
Since this is a quick project, I was just going to use Advanced Circuits PCB Artist for both schematic capture and layout, which is a free download. Ive used it a couple of times and haven't had any issues.

Again, I am doing this for the DIY aspect to help those troubleshoot their SAI, it is not meant to circumvent or violate any emissions laws or regulations. It is simply a toolbox item for RL members who work on their own cars.

I have no intention of making a single penny of profit from this project, and I will gladly distribute the design files and bill of material (which will be sourced from DigiKey)

"Ah, okay. So what you originally said is not correct."

Not really! You need to re-read your question and my response.

"does this enables us to physically remove the SAI system from our cars, including the OBDII ones,"

"No! All it does is fool/mis-represent what the O2 sensors 'see' when the
SAI air pump turns 'on', i.e. It basically indicates that an adequate amount
of air is reaching the O2 sensors during a cold start-up. "

The SAI system includes the not only the air pump but:
1. the O2 sensors
2. the SAI monitor diagnostics within the ODBII system
3. the relay which turns the pump 'on' and the by-pass circuit
4. air valves

So one can't really remove the SAI system!!!!!!!!

Potential Problem with the proposed by-pass circuit:

On the '97/'98 DME ECM the SAI monitor may look for a voltage
change on the O2 sensors and NOT an immediate zero volts
from the O2 sensors with the by-pass circuit. So a SAI fault
still may occur.

Bottom line: Before asssuming that the by-pass circuit is the
end-all fix for ALL 993s, thorough testing needs to be done on
all 993s, i.e. Since later/early 993 DME ECMs had different OBDII
firmwares and thus the by-pass circuit may have different effects.
Furthermore, if the by-pass circuit is not grounded in the ideal location
or the circuit is not shielded from 'noise', the circuit may not function
properly and additionally cause the O2 sensors to provide erroneous
voltages, thereby causing additional fault codes.

It would be a simple circuit to design for this (voltage change), assuming the voltage levels were provided.

"It would be a simple circuit to design for this (voltage change), assuming the voltage levels were provided."

Probably not that simple, i.e. One would have to characterize the
actual voltage change that was required. For example, the OBDII system
may what 'see' the O2 voltage start at .45 volts and have a time constant
range of 2-3 seconds and have a minimum voltage of 20-30 millivolts.
If the desired change is not 'seen', then SAI monitor is not set and
a fault code (CEL) results.

I thought about it for 30 seconds ... I'm pretty sure it's not rocket science.

I don't need it right now, but good to have just in case. Please add me to the list!

Thanks for the technical explanation. I do agree this is not a fix all for all cars in this situation but it is working on two 993s as data points. I will be interested in getting feedback from '97 and '98 993s.

Add me to the list for an assembled board please!

Please add me to the list. I'd like (2) of the assembled boards.

Thanks for doing this!

Please put me down for 1 of the assembled boards also.

Great work!

Lewis, Please also put me down for two assembled kits! Thanks for the contribution to Rennlist! We all appreciate it!

PLZ put me down for one assembled kits.......we can't thank you enough!!!!!!!

Sign me up for one assembled board. Thx Lewis.

'97 Blk/Blk C2S

Please count me in for one. Thx

Great idea!!! Please add me to the list for one assembled and on un-assembled unit.

Thanks

Is there a way to check the function of the circuit before it is installed? If I apply 12 volts to the + and - is there a specific voltage or range I should see at each O2 sensor? Do they go to ground or do they show a small voltage?

I would definitely like to be able to test my system. Put me down for one assembled.

Thanks!

-Andrew

The O2 voltage is grounded when 12 volts is applied to the circuit. You could setup a test O2 sensor to the circuit on a testbed with a volt meter across the O2 sensor. I used a previous old O2 sensor to testing.

Right on Lewis...you da man!

Please add me to the list...I'll take two. Whatever version is easiest to install.

thanks

Mark

I checked the engine compartment to look for wire routing and circuit board location. There is plenty of room for the circuit in the electrical box on the left side. 12 inch leads for the plus and minus 12 volts will be fine. There are two O2 sensor connectors directly next to the box. 12 inch leads will probably work for them too. The other two O2 connectors are under the electrical cover on the right side. They will need about a 60 inch lead to allow routing along the rear of the engine compartment. My car is a 96. I don't know if the O2 connectors are in different places for different years. You might want to check.

"They will need about a 60 inch lead to allow routing along the rear of the engine compartment."

Potential ignition noise problem! Shielded wires may be needed.

Also, a small box should be used to enclose and protect the circuit board.
And if a kit/circuit board is provided, a box should be provided too.
Mickey Mouse solutions not allowed!

Yes, a box is needed for the board. It shouldn't be just sitting in the electrical box. It should be pretty easy to find some 2 conductor shielded cable.

As a technical handicapped person I'm more than willing t pay a premium for a plug & play solution. Looking forward.

Jack

Please put me down for 1 of the assembled boards also.

Thanks for doing this.

Emerald

I worked a bit on routing my wires to the O2 sensor connectors. The wires need to be fairly small to fit into the connectors. I would suggest a 2 conductor 18 or 20 gage wire. Since it only takes a sensor signal, you could probably go down to 22 gage. I'll try to post some pictures if I can figure out how.

I used 24 gauge shielded.

Please put me down for 1 assembled! Thx Lewis!

I would love to have one as well.

Thanks a bunch,
steve

I'd like to get one as well, please. A kit is fine.
Although my SAI is OK now, it would be nice to havejust in case I have to "troubleshoot" in the future.
Thanks!!!

I installed my circuit today. I used the 1x2x3 project box and 2 conductor 24 gauge wire similar to Flying Low. This is far from plug and play. It is not difficult, but is tedious to connect the wires into the O2 connectors. I also drilled a couple holes in my electrical box to route the wires out. I could not find a readily obvious ground in the electrical box so I routed the ground wire to the gray wire on one of the O2 connectors.

I cleared the CEL and now I'm waiting for all the readiness checks to set to see if the CEL comes back.

Hi Lewis,

I'd like to get an assembled kite also, please. My SAI is OK but it willl be nice to have.

Thanks,

after reading all of this and looking at the schematic, is there any reason why a 4PDT relay wouldn't do the same thing? mil-spec crystal can relays are readily available surplus and other form factors can be had new - I would think that a relay solution would be far more immune to EMI/EMC and since it's a single part, would be easier for everyone. the kind of relays I'm thinking of are like the ones shown here http://www.surplussales.com/relays/crystalcan.html - if all you find is DP then just use two of them. full mil spec relays won't be bothered by the heat in the engine compartment either.

any thoughts?

If its not mechanical, I can barely figure it out. Those relays are fairly small. You still need a base or board to wire them to. I assume that a EE guy saw the opportunity to use some transistors as a switch and they took up very little space.

Wow! Thank you for proposing this Lewis. I would like to sign up for this too - with a '97, so we will see. No worries about guarantees, and be glad to remit any premium required for an assembled one. Two left hands in the electrical dept.

Hello,
My apologies for not posting in this thread for a while; my septic system at home recently failed and I've been dealing with ... :surr:

In any event, today I completed the schematic capture and PCB layout.

Prior to ordering, I just wanted to update everyone on pricing vs quantity ordered.

For the bare PCB, no components (2 sided, 1.75" x 1.75"), the price per board is:

$28.26 each for qty 10
$11.94 each for qty 25
$6.50 each for qty 50
$3.78 each for qty 100

(this is typical for PCB fabrication. they run 1-2 panels at a fixed cost and you pay this price, no matter how many circuits you get on a panel.) The PCB is being fabricated by Advanced Circuits. I've used them many times in the past, they are a US on shore PCB fab house.

As far as enclosures, it is optional. I have designed the PCB outline to fix this inexpensive IP54 plastic housing (about $1.50 each):
http://www.mouser.com/ProductDetail/...mIxZS2NA%3d%3d
Again, it is up to you whether or not you want to use this small enclosure or not.

As far as terminations, the PCB will accept either soldered wires or it can built with wire to board terminals (simple screwdriver to connect/disconnect):http://search.digikey.com/us/en/prod...036-ND/1826899
(these are about $0.25 each and the design accomodates 5...one for 12V/GND and then one for each O2 sensor)....again, optional if you wish soldered wires.

As far as components, there are the 4 transistors, one diode, 2 caps and a single resistor array (makes it a bit easier to solder/assemble for those wishing a kit building experience).
I would estimate these components together to cost about $2.00 or so.

Again, the selling price will be EXACTLY the parts cost + shipping and handling (I think USPS Priority mail is about $5.95)

Please let me know how many people are still interested in these (assembled or kits) and if you prefer the terminal blocks or soldered wires and or an enclosure.

The PCB fabrication time is one week, plus shipping time, followed by assembly (I should be able to build a couple a night, even with my quickly diminishing eyesight!).

Each kit (or assembled board) will ship with a hardcopy of the schematic and the PCB layout to aid in assembly and integration.

Regards,

Lewis,

I'm still in for 2 assembled boards complete in enclosures. Let me know when you are ready to accept payments.

Thanks again for doing this!

Somewhere along the way in this thread I jumped in for one... I'm still in for one assembled, soldered unit. And please, you're doing all the work, add in some labor, and let us know the easiest payment method for you (assuming PayPal, but whatever works best).

Just a thought - that pricing curve on the PCB's is very steep (good).

The difference in total $ outlay for 10 boards or 100 boards is less than a hundred dollars. Might as well put in an order for Q100!

There are a lot of 993's here that are going to need this...

Best,

Matt

Lewis,

I am in for 2 please. Great item to have in case I ever need one.

I took the liberty of going through the thread and making a list. Looks like we're at 49 interested, with some folks wanting more than one.

Thanks for taking the time to do this Lewis.

Confirming my desire for one assembled with enclosure and terminal blocks please.Thanks!

I'm still in. Prefer the assembled version as well. Thanks again Lewis!

I am still in for two ( 2 ) assembled version of the units. If you want or need the payment and shipping information before starting the process please let me know. Lewis, Thanks again. John

I'm in for 4 assembled units. If we need more to make a key number of unit, let me know as I can pitch in for more units.

Lewis I insist on paying you for your R&D and labor. This is America.

Please add me to the list for 2 assembled units w/ enclosures and term. blocks. Thank you!

This will be a great tool to have. :)

Thanks Lewis...I'm new to the mix and would like one kit w/enclosure... looks like you have plenty of assemblies to do. I could probably do some after I hone my skills on my kit. I've PM'd you with my contact info.

-Bob

Thanks Lewis
 

Please put my name on one fully assembled kit with the enclosure.

Hi Guys,

I amended the list that Paul M put together - it might be easier to just continue to add to this list by filling out the quantity next to your name. Some people, I couldn't find a definitive request as far as quantity of units. Please confirm the list.

Also, given that there's an option to add the enclosure or not, to make things simple would it be easier to choose: a) default is w. enclosure OR b) default is board only? Obviously, I was just thinking of trying to make Lewis' job easier in terms of tracking all the different order variants.

Finally, I would agree with NP993 - looking at the orders this is no insignificant amount of work (heck, just organizing the shipping alone is a fair amount of effort - nevermind the assembly of the kits)...it's incredibly generous of Lewis to do this and I'd have no problem adding some kind of labor on top of this.

Thanks again Lewis!

Jack

I'm not in on this so I'll comment as a third party. Lewis, you are being way too kind. From past experience I know that whenever someone tries to charge the exact cost on something like this he/she ends up at least a few dollars short. I applaud your determination to do this for free (ex-parts cost) but you should have a small margin at least to cover the inevitable shortfall. I roughed out your parts cost at about $17 so I'd suggest just charge $20 so you're fully covered on costs, even though I personally think you should charge quite a bit more and doubt any here would mind in the slightest. JMHO.

Completely agree!

I think Lewis is being overly concerned about making a profit off of RL w/out being (and paying for) vendor status. I can understand his concern esp. in light of him being a Mod.

I think it's been done before but just a suggestion, if LTC uses Starbucks we could get SB gift cards and do it that way rather than having him sell these for a profit.

To be clear, I think he's being overly cautious but I respect his position of concern.

Yes, I would like 1 pre-fab board, w/ enclosure & w/ term. blocks.

I would also like to add... that there can also be an incidental cost if something doesn't work out, gets damaged, has to be re-shipped etc...

can i suggest you take the advice of 2ManyCars and Blue TTop, and round up the price.... $3 is not going to make or break anyone here... and I believe you and the owner of this forum have a good understanding.... you can just decide to make a "Rennlist Donation" if this does indeed become an issue.

I previously made an "at cost" item for another board.... and... if it werent for the generosity of people who gave me DOUBLE than what I asked.... I would have taken a loss at the end of the day....yet... i was still able to ship internationally to people, etc... all for a really low "advertised" price.

Thanks Paul M (and Ash) for making the list... and my standing order (which is on the list)... is for a full complete assembled box w/enclosure and terminal blocks.



ps: any chance of getting a unit out this week?

I'll take one

The list is 65 strong at this point. Even if Lewis were to get $20 as 2Many and Blue suggested, that's hardly reason to be concerned. Larry would not have been concerned! If it's enough, then just make it $20!

I'm also on the list for a fully assembled box with enclosure and terminal blocks plus whatever Lewis is charging,I'm sending an extra $10 because this is above and beyond the call of duty!!!

Count me in for a complete unassembled kit with enclosure and terminal blocks. Thanks to Lewis for taking this project on and I will happily pay a price that makes it worth your time and effort.

Hi Lewis

I will take an A). thank so much you are a champ.

Dave

I'm still in for an asssembled one. Let me know when you know the final price so I can send you the funds. Thanks Lewis!

Definitely would want one with the enclosure. Please upgrade my order to include that :)

Thanks everyone for all the help with tracking orders, and thanks for ltc for doing all the real work!

Hi Lewis,

Put me in for 1 assembled box with enclosure. Thanks for taking the initiative and I would happily give an extra donation for your time and effort.

Hello Lewis,
Please count me in for two full assemblies with enclosures and terminal blocks. Please tell me how much to send you. I'm also sending extra $$$ because this is above and beyond what is expected.

Thank you so much !

Bill

Update on the list. I don't mind updating this every day or two. It's looking like some want enclosures, some don't...and some are specifically asking for terminal blocks as well. I think it's up to Lewis to determine how granular the options he feels comfortable in carrying out for the different orders in addition to how he'd like to define what a 'default' kit should be :).

In the meantime, I'll do my best to keep the list maintained as an impromptu record keeper. Please do check your name on the list though and if there's an error, let me know and I'll correct it when the list gets updated.

Perhaps for now, unless otherwise spec'd, we'll assume that a number beside your name means you want an assembled kit with an enclosure and terminal blocks?

Please put my name on one fully assembled kit with the enclosure. I sent a PM. Thanks a million for doing this guys.

Could you put me down for the full kit please? Thanks so much!! Incredible family as usual!

Please update me for 2 kits also fully assembled.
Many Thanks

Fabulous undertaking!
I'm on the list, but please put me down for 2 fully assembled.
again, thanks

Please add me to the list for 1 fully assembled with enclosure, just in case.

Thanks in advance.

Brett

Lewis,

By my count this morning, it looks like you have been asked to construct about 75 +/- kits for this project! This is a huge effort. Is there anyway we can assist you in doing this? We all appreciate what you have volunteered to do; but, did you expect the response to be of this magnitude?

In for one kit please, don't care on the assembly.

Thanks!

Please add me to the list for 1 fully assembled.

Thanks flying_low. Thanks RL

Hey Lewis!

Please count me in for two full assemblies with enclosures and terminal blocks.

Just lemmeknow how much to send you, and I'd also like to send a little more because you are going the extra mile.

Cheers!

Update (As always, if you're a recent addition, make sure I've got you down correctly :) )

Hi everyone,
Just a quick update. I am posting this on an iPad, from the bottom of a hole where my septic tank used to be, waiting for the new tank to arrive. Yes, I know, sh!t happens, i've got the T-shirt ... and I've learned a lot about septic systems in the past month.

I will be sending the PCB files out this weekend after I do the final dimensional checks and package checks. Based on the current list, I will be ordering 100 boards, so we will get the best price.
As soon as the PCB files are out for fab, I will also order the components from DigiKey and the boxes from Mouser (for those who want the enclosure...you can mount this on your own with velcro or your own box).

In order to simplify things, I will probably go ahead and build all the assembled units with the wire to board terminal blocks, rather than solder wires to the PCB. This allows folks to choose their own style/size/color wires.
If there is anyone who does not want the terminal blocks and must have soldered wires, please let me know how long and what type of wire and I will do my best to accommodate.

Once I receive all the boards and parts, I will be able to determine the exact cost per unit (parts + shipping). I will post that information in this thread.

As far as assembling and soldering, it's not big deal. It will actually be relaxing, as I've been doing this since I was a kid. Doing 1 or doing 75 really won't matter.

Once assembled, I will start sending PM's so folks can provide me their shipping addresses. Inside the package will be the unit, a hardcopy of the schematic, a hardcopy of the PCB layout and a return address envelope. When you get the unit and everything is OK, just use the envelope to send payment. I am a trusting person when it comes to RL members, so I have no problem sending out the units prior to receiving payment.

Sorry it's taken a bit longer than I would have liked, but between work and the septic failure, it's been "fun".

Ok, I give in, I'll get one too. Fully assembled one please. Thanks!

-nelson:burnout:

:bowdown:

:bowdown:

Thank you but I am anything but deserving of that. Just trying to give something back in exchange for all the help I've gotten over the years.

Besides, assembling electronics will be much better than shoveling sh!t ... the only ones happy about the current septic situation are the dogs.

Lewis: Larry would be proud of you!

If it's not too late, put me on the list for one fully assembled kit with the enclosure.
Thanks!

It seems like a great insurance policy - please put me down for one assembled - is there any info on how/where to remit payment?

Please see post # 147 in this thread for details ... basically you will be mailed your board (or unassembled kit version) and in the box will be a return address label.
If everything is fine, you can use the envelope to send a check, money order, S&H Green stamps (are they even around anymore) or a Dunkin Donuts gift card ;)

I will be ordering PCB's and parts to supply 100 units, so there appears still be units available.

I will update the thread this weekend after I submit the order for the PCB's and electronic components.

Please sign me up for a fully assembled kit w/ enclosure.

Thanks so much for putting this together!

:cheers:

Matt

Hi everyone,
Here is the latest weekend update ...

100 bare PCB's have been ordered from Advanced Circuits, 5 day fabrication (cheapest) with UPS GND shipping (cheapest).
$376 (pcb's) + $20.64 (UPS) = 396.64 ... so less than $4.00 per bare PCB.

Components to populate 100 PCB's have been ordered from Digi-Key with UPS GND shipping.
$237.83 + 14.86 (MA sales tax) + 11.26 shipping, $263.95 for parts to build 100 boards.

I still need to review the list put together by Ash (thank you again) in this thread and order enclosures for those who wanted these included with their order. Those will be coming from Mouser electronics (they were in stock at the cheapest price...$1.50 each or so.

My bride has graciously agreed to help me with the logistics (keeping the list of who ordered how many, email/PM, printing shipping address labels on the Dymo label maker, and taking the units to post office. This is good news, since I am not able to balance a checkbook, so I know she will keep things moving smoothly.

As soon as the boards and parts arrive, I will begin to start assembling boards (except for those who wanted the "Heathkit" version ... they will be bagged into kits).

Again, thanks for your patience and I will keep everyone informed via this thread. We should be shipping these out in a couple of weeks.

Please find attached snapshots of the schematic and PCB layout ....

You will note that the PCB carries text denoting wire colors, functions, etc. The PCB is 1.73" x 1.73"
The schematic carries all the Digi-Key and manufacturer part numbers as well.

I'm speachless and truly deeply thankful for your efforts. I'll include you in my payers - rigth after my 993's ....

Thx again.

Jack

Oct. 16 update

Thank you again Ash for keeping the list updated.
I have entered your latest list above into Excel and have 79 assembled units requested, 4 kit (unassembled "Heathkit" units requested) ... 83 total and 2 requests for plastic enclosures.

At 83 total, I should still have parts for 17 additional requests.

If everyone could just please check Ash's list above and correct any mistakes, that would be great.
I would really feel bad for someone to order an assembled unit and get a bag of parts instead .... or rob someone who ordered the kit version the "thrill of soldering" .

Hi --

If it's not too late, I'd love to get two assembled kits. Thanks so much for putting this together -- really epitomizes the rennlist spirit!

Updated. Thanks again! It is really appreciated!

Looking back at the thread, some people indicated that they were interested in the assembled board prior to Lewis' addtion that the enclosures could be optional.

Also, unless otherwise specified below, it is assumed you want an assembled kit.

I believe that Lewis is going with terminal blocks as standard.

I have updated the list with a note for those that have specifically asked for enclosures. (I also just noticed that Jim W had appeared twice in an earlier list so I've removed the duplicate)

As Lewis mentioned, please check your name and request and update as necessary or post here and I'll update.


Thanks,

Lewis
I am in for two as well,just in case.How do you want payment?
Thanks

See post # 147 for payment details.....

Just a suggestion Lewis, you might want to bold the paragraph with the pmt. info.

Lewis, I am currently on the list for two, Can you add assembled for both for mine. Thanks John

Done.

No problem.

Monday noon update - Please review your preferences :)

Quick reminders:
1) unless otherwise noted, it assumed you are asking for an assembled kit.
2) enclosures are optional - feel free to update/ Post a reply/ PM and I'll update the list if you are looking for an enclosure.

Payment Info posted by Lewis (from post #147):
Once assembled, I will start sending PM's so folks can provide me their shipping addresses. Inside the package will be the unit, a hardcopy of the schematic, a hardcopy of the PCB layout and a return address envelope. When you get the unit and everything is OK, just use the envelope to send payment. I am a trusting person when it comes to RL members, so I have no problem sending out the units prior to receiving payment.

tonypai 1 + enclosure

Thanks again for putting this together.

As of this post/date, if I entered the information correctly into my spreadsheet, we have 84 assembled units, 4 "Heathkit" kits and 32 plastic enclosures.

That makes 88 out of 99 PCB's spoken for, so there are 11 more available.

Again, the unit will be offered as an assembled unit with terminal blocks to connect the wires of your choice (I have done all the soldering) and a "Heathkit" (where you get a bare board and all the parts, so you can build/solder it yourself).

Plastic enclosures can be included with either one.
In case anyone missed it, here is a link to the plastic box (small, easy to mount) that the board will fit into

http://www.mouser.com/ProductDetail/...mIxZS2NA%3d%3d

Back on 9/21, there were 323 in stock. They are now out of stock and due back in on 10/20. So as soon as the list is closed, I will order the boxes and have them available when the rest of the components arrive (sometime next week...I am waiting for a confirmed ship date from Advanced Circuits)

Thank you Lewis! I'd like to get the enclosure too, it looks very nice and discrete.

+ Enclosure for me too please! :cheers:

Hi all, I'm looking at buying a 993 in the near future but i'm sticking to a 1995 due do all the SAI issued related to the 1996 plus years..Would the item (Board) you guys are talking about fix the problem...I tried to read the thread, but got confused..Thanks...

Mr. Ash, wonderful job keeping the list up to date. We should change your title to "Keeper of the List"!

1 plus enclosure

Thanks for doing this Lewis :cheers:

Please update mine to 2 + enclosures.

AW21 - Andy
Thx!

Hello. Please include me for 2 un assembled kits and 2 enclosures. I just finished touching up my cab controller cold soldered connections, so I'm feeling lucky.
Thanks Lewis for your time and effort!

Jeff

Would like to add an enclosure to my order, #13 on the list. Thanks so much for doing this!

Having only just discovered this thread, I am yet again amazed by the spirit and altruism of its members. I hope that I am not too late to put my name on the list for a module plus enclosure. I am a Canadian member, but can provide a US shipping address. Can we also agree on a price which pays our fearsome electronics whiz for his valiant effort?
Yours with the usual problem

Richard Lee

Also her for #23 - if the enclosure is not already included in a full assembled versin I would like to add 2 of it - if possible.

Thx Jack - and again thx for the great effort.

I am sure Ash will update the list and then I will update my Excel spreadsheet from that.
I will be shipping via US Postal Service, since it should be the cheapest.

As for the price, it will be the cost of the parts (PCB + components) + actual shipping. I am keeping all of the costs posted in this thread for the 100 unit build. I am not doing this to make a profit. All of the costs are posted in this thread.

IIRC, we are still under $10 per unit (~$4 PCB, ~$3 parts plus ~$1.50 enclosure) so add to those numbers whatever USPS first class would be (need to weigh the first one and then get the smallest envelope possible) + a trip to Staples to buy a roll of Dymo shipping labels (I have a Dymo LabelWriter which will make labels quick and easy) and a box of small shipping envelopes. I will probably need to order a roll of solder as well !

As of this post my spreadsheet shows 85 assembled units, 7 "Heathkit" units and 43 plastic enclosures.

That means 92 PCB's have been spoken for....7 more and then there are no more.

DigiKey UPS tracking shows parts being delivered to my home next Monday.
The PCB should be shipping next Monday (need to confirm once they're ready to ship).
Plastic boxes will be ordered last, since they should be in stock on 10/20.

I'll take an assembled unit

Dan

Ash,
I have received PM requests for the following additional units.
Could you please add these to your list above (thank you for the color coding of the kits vs assembled)

bootman30 1 assembled
mpgandco 2 assembled + enclosure
77'3.6vram 3 assembled + enclosure

Also, I think at this point all of the avaialble parts (100 ordered) have been spoken for, so once these members are added, I think the list should be closed.

I am on the list for one at number 28 but could you add an enclosure?

*Edit- Wed. night - added efong and fullbooker - enclosures for both

This list is now closed - pending final count.
Please check the list for your name and your order. :)

Thanks again for doing this!
Phil

As of now, 19 October 2011, 7:15PM, based on Ash's list above, we are at 100 units..
91 assembled, 9 kits, 53 enclosures.

Based on the fact that I ordered parts for exactly 100, I think we are definitely going to have to close the list.

Just received an email from Advanced Circuits:

Part Number 993 PCBs have shipped from Advanced Circuits!
Waiting for UPS tracking # tonight.

DigiKey has already shipped the components, expected delivery is Monday, so the boards should be right behind them.

Now that the list is closed, I can get a final total on plastic enclosures and get those on order.

Awesome. Great news Lewis.

Ahhhh crap..... too late? :banghead:

Well, if there is anyone out there with second thoughts, or will have an extra let me know i would like a fully assembled one with an enclosure.....

I guess I am officially #1 on the 'Waiting List'.... unless Ash, in the unlikely chance, miscalculated by one?... I can only hope.

Update:
Parts arrived from DigiKey today.
PCB's are scheduled to arrive on Wednesday.

I need to update my spreadsheet against the master list from Ash and then order enclosures from Mouser.

With any luck, assembly will start late next week and into the weekend.

I will probably do an electrical functional test on the units once assembled (apply 12V, verify that the 4 output FETs conduct).

Things are moving along ....

A waiting list is certainly possible, the issue would be the price of the PCBs.
It is approximately $350 to run a couple of panels, so essentially you pay $350 for 100 boards or $350 for 5 boards.
So unless we get another 100 people, the unit price would be higher; the exact amount would be based on the total number ordered
(earlier in this thread I posted the prices for 25, 50, 100 pcs ....)

Hi Lewis...
I'm #37 on your list, and if possible I would like to add the enclosure please.
Thanks!
_____________
'97 Blk/Blk C2S

Please add an enclosure to #74. Thanks for the flexability on ordering.

If not too late, please add 2 ea. enclosures to #20. If too late, no problem. Again, sincere thanks for both your efforts. They are very much appreciated.

Edit: According to Lewis, there is still some time to add enclosures so I'm editing the list for those that have asked for them. (In this round, I've added enclosures for: Richard W, Don't Lift, Dbog, and NC Trackrat)

This list is now closed - pending final count.
Please check the list for your name and your order. :)

Hi Ash

please include an enclosure with my order and many thanks to you and Lewis
Dave

number 40...

please add enclosure, thanks!

Just found this, crap. Too late. If anyone cancels or there is a second run please put me on the wait list. Teaches me to just cruise the turbo forum.

I have no problem starting a second list or producing more units.

It is a simple matter to reorder material, as the design is already done; the only issue would be the price per unit, which is solely a function of how many PCB's are ordered.
Please see earlier in the thread for the PCB unit costs when ordering 25, 50 or 100.

Just let me know how much and where to send the money!

If it's not too late, I would like the enclosure as well. Or whatever version of the kit that is the most complete possible. I'm not an electrician, so the less assembly for me the better. Many thanks again.

Edit: Added 2nd List request from lizSter, added enclosures for TxnBluDvl (don't know if Lewis has ordered enclosures already or not)

This list for the first round of boards is now closed. I've started a Waiting/Back-up list below for those that missed this first run.

Quick reminders:
1) unless otherwise noted, it's assumed you are asking for an assembled unit.
2) enclosures are optional - feel free to update/ Post a reply/ PM and I'll update the list if you are looking for an enclosure.

Payment Info posted by Lewis (from post #147):
Once assembled, I will start sending PM's so folks can provide me their shipping addresses. Inside the package will be the unit, a hardcopy of the schematic, a hardcopy of the PCB layout and a return address envelope. When you get the unit and everything is OK, just use the envelope to send payment. I am a trusting person when it comes to RL members, so I have no problem sending out the units prior to receiving payment.

If any enclosure are available, I would like to added them to my order also. Thanks. John

Note to self: READ THE DAMNED STICKIES!:banghead:

Can I be put on a list if this goes two rounds? I'd like 2 fully assembled with the enclosures and anything else to make it complete.

Lewis, this is more than generous.:bowdown:

Here is the PCB pricing from post #107 ....

$28.26 each for qty 10
$11.94 each for qty 25
$6.50 each for qty 50
$3.78 each for qty 100

Again, I don't mind doing a second round. If there aren't 100, they will just cost a bit more than the first round.

Or if someone would like to go it "on their own" , I will gladly provide the schematic and artwork files.

If we can get the waiting list to at least 10, I am in! Thank you Lewis.
 

Thanks again.

(edit: Thanks Bill)

Just as an FYI, to correct the title line click on the "Edit" button on the bottom right, then click "Go Advanced". That will allow you to edit the title line.

No problem.
Again, I don't mind a second round.
I just want to avoid confusion or issues regarding the possibility for the 2nd round units to be more expensive than the 1st round units, simply due to the number ordered.

I am charging exactly what these cost, I post the actual prices for the parts + shipping.

I would also take a kit.
97 993

Round 2 List: See Ash's current list at post #212
 

Yes Lewis, we understand that the cost is greater this round. Thats just the way it goes for us that are slow at the switch! It is still cheap at this price.

Lets get to at least 10! $28.26/ each (or so)


Thank You, this is very generous of you.

From post # 187, the components (R's, C's, diodes, FET's, terminal blocks) are about $3.00 per board, the enclosure is about $1.50 per board, then add shipping.
So the major cost of a second round (less than 100) will be the PCB.

If it's still possible could I get an enclosure? Number 44 on list. Thanks a bunch for everything.

Kraftsman - done :)

I've been updating the list in post #212 so please check.

:cheers:

I would love to have an assmebled unit with enclosure. You guys are the best!

Hi Tom...added. :)

Update:
PCB's have been received from Advanced Circuits.
(unfortunately UPS delivered them to the wrong house, so it wasn't until my neighbor came over this morning did I finally have them).

Now that the list seems to be settling for plastic enclosures, I will add them up this weekend and place the order this weekend.

If it takes me 10-15 minutes to solder all the components onto one PCB, that's 4-5/hour, so about 20-25 hours of assembly for 100 units (hopefully I can do it a bit quicker)....that means if i can get a few hours each night, I should have them ready to go in about a week or so.

I will keep supplying updates as I go along.

As soon as they start rolling off the "assembly line", I will start asking for PMs with shipping addresses. Then my bride will take over the logistics department!

Lewis-
Dumb question: Although it's probably a remote possibility, can you think of any way to do a simple QA test on the assembled board to ensure that there are no faulty components?

As I mentioned earlier in this thread, I would simply apply 12v to the input (blue/grey) and verify each FET is conducting...use a DMM on Ohms or equivalent.

The circuit is fairly basic.

As of this morning, I checked my spreadsheet against Ash's master list from post # 212.
We have 90 assembled units, 9 "Heathkits" (kind of nice surprise) and 63 enclosures.

I will probably assemble the first unit tonight and run some quick checks on the bench to verify it performs per the schematic
(this will be simply done by applying 12V, then measuring that the output FETs have turned "ON" .... then removing 12V and measuring that the output FETs are "OFF". This can be done with a 12V battery (actually you could use a 9V battery as well) and a hand held meter).

Once everything looks OK, then "mass production" will begin.

I am going to contact the local post office to ask them to order 100 of the USPS Priority Mail boxes. It seems like the quickest/easiest way to send the units out to everyone at a flat fixed rate.

No problem. I think I was at 4k posts before I figured that out so you're well ahead of me.

Unit #1 has been assembled and electrically tested.

It's Alive !


http://images.fanpop.com/images/imag...30_340_255.jpg

Always concerned that something happens with library symbols, net list transfer, fab files, etc, but everything went perfectly.

So, 90 assembled units, 44 solder joints per unit ... Let the fun begin :cheers:

Wow! Only 3,960 solder joints left......... ;)

for what it's worth, I'm trying an experiment with a 4 pole relay that I had lying around that has a 12V coil - it's not as light weight as solid state, but it's another approach to do the same thing. It will be interesting to see if this works for most people

hi,
I'd like to be added to the waiting list for 1 assembled with enclosure.
thanks much!

I'd like to hear others report that this method of shorting the O2 sensor outputs to a single ground work to clear the SAI fault - if it does, I wonder why the relay approach doesn't seem to work - the CEL is on still after 4 or 5 drive cycles.

Ack! Just got back from a week of business travel without real internet connectivity and noticed that there's been discussion of enclosures.

If it's not too late to get my two with enclosures, I'd love to get them too. Sorry for being late to the party!

Added TxnBluDvl's request for enclosures - not sure if Lewis has already ordered them prior to your request

Also added LizSter's request to be put on the 2nd round list.

See Post #212 for list updates.

think i figured out why the relay wasn't doing the trick one contact pair must be not closing, I can see normal voltages on one O2 sensor - maybe that's next week's troubleshooting.

Wow...this is more of what I get for having been deployed...is it too late?
Would love two assembled w/enclosures! Thanks.

~Dave

Hi! If possible I whould like to be added to the list.
1 assembled w/enclosure.

Update:

45 units assembled (half way!)
9 kits bagged

Once the last 45 units are assembled, I will electrically test each one and then we can begin shipping.

I will make a trip to my local post office with an assembled unit and a plastic enclosure to see what the cost would be for first class mail (in a 6x9 manilla envelope) vs Priority Mail Small Flat Rate box ($5.20).

66 enclosures (based on Ash's list and my spreadsheet) and screws (for cover and PCB...need to order in packs of 100, so I ordered 2 of each) have been ordered today from Mouser. In stock and will ship USPS Priority Mail (cheaper than UPS or FedEx).

Total for 66 enclosures + 200 PCB mounting screws + 200 cover screws was $117.62 + 7.35 tax + 14.99 shipping = $139.96

Here is a link to the enclosures:
http://www.mouser.com/Search/Product...y546-1551RFLGY

Here is a link to the PCB mounting screws:
http://www.mouser.com/Search/Product...546-1551ATS100

Here is a link to the enclosure cover screws:
http://www.mouser.com/Search/Product...y546-1591TS100

I bought the screws so everyone doesn't have to run to Lowes or Home Depot looking for the right size. It should add about $0.25 to each order, which I thought was OK.

Update: just received email that the enclosures and screws have shipped... About 4 hours after ordering.

Definitely a "class act"! A work of art like this deserves recognition. Please sign or initialize and number each creation somehow, perhaps inside or outside the enclosure.

75 units assembled.
Hope to complete assembly and electrical test this week...:typing:

Please add me to the list for 2 assembled units with enclosures. After years of dealing with SAI bullxxxx it will give me great joy to finally slay this EPA dragon. Lewis, I hereby formally nominate you for sainthood. :cheers:

Ash,
please add enclosures to my 2

thank you, this is so cool!
Michael

Finally ... daylight
 

After a marathon weekend assembly session (locked in basement listening to Stevie Ray Vaughn), they're built. 90 assembled units, 9 bagged 'Heathkit' units (the kit versions will also include a small roll of solder as well).

I will do electrical test this week (at night after work) on each of the assembled units.
The enclosures are due in this week as well.
I also need to print out 99 hardcopies of the schematic and 99 hardcopies of the PCB, so folks have them as a reference. On the schematic are all the DigiKey part numbers. These hardcopies will be with each shipment.

Once that is done, I will post for folks to start sending me (via PM) their mailing address information.

My bride (who has graciously volunteered to help with logistics) will then print out address labels on the Dymo LabelWriter. She will also print out return address labels and fix them to envelopes, which will be included with each shipment to make sending payment easier.
She is also going to take a unit to the post office this week to see if there is a cheaper way to send these besides $5.20 Priority Mail Small Box flat rate.

At that point, she can add up all the bills (PCB's, parts, envelopes/labels/shipping) and come up with the final actual cost to date for 99 units.
I should have an update sometime this week .

Here is a pic of the units awaiting test ...

:thumbup: and a very sincere Thank You!

Added Michael993's request for enclosures and Deadeye's addition to 2nd round list.

Lewis...that picture of all those boards is a thing of beauty. Thanks again for doing all this heavy lifting...wow!

~A

Hi Ash,
Unfortunately, the order for the enclosures had already been placed/shipped before the request for 2 additional enclosures.

You are AMAZING Sir ! :cheers:


Emerald

Thanks Lewis...suspected that might be the case.

I suppose we could add Michael993's enclosure request to the second list or he could place the order directly with the distributor?

I would like to get on the second round list:
4 units, assembled with enclosures.

Yes, anyone can order the parts directly from the electronics distributors that I've used.
I have posted links in this thread (enclosures were obtained from Mouser, all other electronic components were obtained from DigiKey).

I also have no issues providing the schematic and PCB files, so anyone could arrange to have PCB's fabricated and assemble their own units, since the design work has been done.

As for the second list, I have no issues with a second run. The exact cost would depend on the # of units in that order, since it is pretty much a flat charge for PCB fabrication (again, those costs have been posted in this thread as well). It will be up to the members.

Added: added coreseller and boostid to 2nd round list, changed Tom97C4S's order to 2 + enclosures

This list for the first round of boards is now closed. I've started a Waiting/Back-up list below for those that missed this first run.

Ash,

Please revise the order for earossi to include the assembled kit in the enclosure.

Thanks.

I know I am late geting to this thread but I would surely like to be on the second list for the part and enclosures, etc. I had a 993 previously and am currently looking to purchase another if I can find a 98 993 Targa. I had one that had the dreaded CEL issue due to the SAI - it was fixed under warranty by the PO that I purchased from. It had the valve guides replaced as well - shouldn't have sold that car but that's another story. I am getting in late - what is the process - do you mail them individually or no? Sorry for asking and this is just an unreal thing that you are doing Lewis. I am amazed at this effort for such a problem on the 993.

Midweek update ....

Minor issue with the electrolytic capacitor hitting the cover of the enclosure....my bad, it is about 1-2 mm too tall using the standard 11mm height cap I chose.
Minor issue with one of the PCB mounting holes not quite lining up with one if the 2 mounting bosses in the enclosure. Won't be an issue.

The enclosures look very nice and are small which should allow for easy mounting.

New (shorter) cap has already been ordered/shipped and as soon as they arrive I will swap them out and finish electrical test.
I will drill out one of the 2 mounting holes to line up, even though one mounting screw is sufficient to mount the PCB to the enclosure bottom.

Sorry for the short delay...I need to work on my metric addition and mechanical skills ;)

If/when there is a second run, please put me down for two complete units with enclosures. No particular rush.

Can't say "thanks" enough to Flying_Low and Lewis for design and production as well as the others who offered their knowledge and expertise.

This is what happens when you don't pay attention to stickies!!!

Lewis...I am in no rush...but if there is another run I will take two assembled units with enclosures.

Thanks for doing this!!! I just did the port flush and it was the least fun job I have ever done!!

Of course I'm late! Damn. If there is another run of these, I'd sure like to get in on this.

So please put me down on the waiting list for 2 units, fully assembled with enclosures.

I'm in complete agreement with other posters; Lewis should be recommended for sainthood. And thank you! Ash for keeping the List.

Mike
'96 993c2

I'd like to have my name added to the 2nd round list for one assembled and with the enclosure. Thanks.

GC

Please put me down for the 2nd round if there is one. I'll go the kit route with enclosure. Thanks!

Update,
UPS did not deliver the new (shorter) caps in time for this weekend :grr:
Now scheduled for delivery end of business day on Monday.
Once I have them, I will install and test the boards.

Sorry for the delay...

Update for those on the waiting list/2nd round.

Per the PCB pricing (bare board) in post 107 of this thread...

$11.94 each for 25 pcs
$6.50 each for 50 pcs
$3.78 each for 100 pcs

We are at 25 people. I don't know if we will get to 100, so the 2nd round cost might be higher than the first.
I will leave it up to the members to decide when to place the 2nd order and if that price is acceptable.

Again, i am charging cost for the materials and shipping, nothing more.

Lewis, speaking for me, I'm not in a hurry so I can wait for 50 or 100. Others may have a CEL currently and need them ASAP. Perhaps someone from the 1st order could help out such a fellow renlister in need. I think over time another 100 will be wanted as more of us READ THE STICKY!!!!! From my perspective you could easily charge $50.00 and no one would complain. :bowdown:

Lewis and Ash, thank you for the work. Been a Porsche owner for many years, a 993 owner for a few weeks now. Please ad me to your list for an assembled unit with enclosure for your next batch........Mark.

Much thanks and appreciation to Lewis and Ash.
Please include me on the second list for an assembled unit with enclosure.
Are the instructions clear enough for an idiot to install this?

Thanks again

Can my order br changed to 2 units with enclosures instead of 1?

Thanks

List has been updated in Post #256

They're finally finished
 

The first batch is finally complete.

Just completed electrically testing each unit, 100% of them passed, no defects or defective components found.
Then each one was washed in flux remover (my hands will be white for a few days...) and dried.

My bride went by the post office. The most economical way to ship these out is first class mail, in a 6x9" manilla clasp envelope. The post office weighed a sample and said $1.75. This is much better than $5.20 for Priority Mail IMHO.

She went by Staples and picked up a box of 100 manilla 6x9 envelopes.
I have printed out 100 copies of the schematic and half of the 100 copies of the PCB artwork (uses a lot of ink!), I hope to finish the rest tomorrow.

I've lost track of time with these things. Even something as simple as electrically testing each one, if it takes 1-2 minutes .... times 100 units .... I apologize for it taking this long, but it has been a lot of hours behind the scenes.

Shipping Information Requests
 

Hi,
Now that they are ready to find new homes, I would appreciate it if everyone on the master list kept by Ash (thank you again) would send me a PM with the following information:

Rennlist user ID
Name
Street Address
City, State, Zipcode

My bride will sort thru all the PM's, print out mailing labels on the Dymo LabelWriter, and then pack each 6x9 envelope with the requested items, schematic and PCB hardcopy. She will also include a self addressed return envelope for mailing payment (check, money order, cash, Dunkin Donuts gift card, S&H green stamps) once you have received the units. For those who requested enclosures, I will try and include an extra screw or two...they're small and I am sure one will be dropped or lost by someone along the way! I think I bought enough to allow for this.

As to the final cost, now that we have shipping info and materials purchased, she will add up all of the costs to date (parts, PCB, shipping, misc materials (envelopes, labels, etc) and then divide by 100. That will be the actual cost per unit.
We should have that done in the next few nights.

For those of you who ordered the DIY "Heathkit" version, I need to type up a quick little document to aid in the assembly. This will be included in the 6x9 envelope along with the schematic and PCB artwork hardcopies.

Due to the nature of polarity sensitive components (the bussed resistor array, diodes, electrolytic cap, etc), I just want to include a little note to eliminate assembly errors.

Each kit includes a small roll of solder, sufficient to build a unit with solder to spare.
I will also try and include a small piece of Soder Wick (desoldering braid) in case of an error during assembly. I should have some down in my workshop, I just have to dig thru some drawers.

Lewis,
I just added my name.
Thank you again for your work and support of 993 owners.

Gary

Lewis, you have a PM with shipping information you requested. Thanks

Hello Lewis -

Please sign me up - round 2 - for the "whole enchilada" (assembled / enclosure etc).
I'm in no hurry, and as so many others have already stated - Many thanks for your efforts!

If you can add me to the second round as well, that would be great. Entire kid with enclosure if possible.

Cheers,

Mike

Moving this list to a new page to track easier

Added: updated GD993C4

This list for the first round of boards is now closed. I've started a Waiting/Back-up list below for those that missed this first run.

Quick reminders:
1) unless otherwise noted, it's assumed you are asking for an assembled unit.
2) enclosures are optional - feel free to update/ Post a reply/ PM and I'll update the list if you are looking for an enclosure.

Payment Info posted by Lewis (from post #147):
Once assembled, I will start sending PM's so folks can provide me their shipping addresses. Inside the package will be the unit, a hardcopy of the schematic, a hardcopy of the PCB layout and a return address envelope. When you get the unit and everything is OK, just use the envelope to send payment. I am a trusting person when it comes to RL members, so I have no problem sending out the units prior to receiving payment.

Final cost summary for 100 units: $10.74 each
 

Hi everyone,
Here is the final financial accounting for the first 100 units.

The breakdown for 100 units is as follows:
6x9 shipping envelopes $12.00 (Staples)
6 3/4 return envelopes $7.50 (Staples)
DymoLabelwriter labels $26.00 (Staples)
Paper/Ink $25.00 (Staples)
Postage $175.00 (USPS First Class 6x9 small parcel)
PCB's $397.00 (Advanced Circuits)
Electronics $291.50 (DigiKey)
Enclosures/Screws $140.00 (Mouser)

Total: $1074
If anyone is interested, I can find a scanner and post invoices and receipts.

It was right around this time when my bride looked at me and asked how much I am adding for my design and fabrication time. I kept my head down and pretended to cough.

She then asked that people are going to send money before you send the units out, right? I kept my head down and muttered No, they're RL members, I trust them.

She then laughed and asked "tell me again why I married you and why I've stayed with you for 30 years?" Yup, head down. I know why I asked her to marry me, but I'll be damned if I can answer her on this one...:D

In summary, each unit cost $10.74 to fabricate and ship. I have tried to keep the unit cost as low as possible.

16 November shipping list -- 19 units
 

Hi,
The following RL members' orders have been packaged and are going to the post office tomorrow morning:

Aircooled Dave
tonypai
fullbooker
Shahrams
tbil
Ash
C4SJOHN
Jeff96-993
Kaefer
Don't Lift
M Fig
Blue TTop
earossi
Teddy2
TxnBluDvl
mpgandco
Jscanavan
77'3.6vram
GRINBOB


These have been shipped based on first come/first served receipt of PM's with shipping info for those who are on the first list.
Please watch your mailbox for a 6x9 manila envelope from Massachusetts.

20 per night is about the limit that I think my wife and I can do. Please try and be patient as we work thru the list.

It took us about 2.5 hours to get these ready. It sounds like a long time, but 2.5 hours is 150 minutes, divided by 20 orders = 7.5 minutes per order.
Each order needs an address label printed, return address envelope printed and inserted, schematic and PCB layout inserted, enclosure + screws prepared (I have put the PCB inside the enclosure along with hardware to help protect it during shipping)....so 7.5 minutes is what it takes once we get rolling.

Again, inside each 6x9 envelope is your order, a schematic, PCB layout and a return address envelope. If you ordered an enclosure, the screws are inside the enclosure. If you ordered a "Heathkit", all the components are inside a Ziploc snack bag. Please check to make sure you get everything out of the envelope.
All units have been 100% electrically tested, so hopefully there are no issues when they arrive to you.

Lewis

On behalf of everyone.....THANK YOU!!!!

Tony

Can you please add me to the waiting list for one complete kit with enclosure.

Thanks very much!

Fantastic! Looks like my kit will be mailed to me sometime this week. In prepping for the installation, I went back and re-read this entire posting. Early on, someone speculated that the firmware design for the 97 and 98 model 993's might be different from the earlier 993's and that the CPU might be looking for a "change" in voltage rather than a drop to zero. There were several messages exchanged on this bit of speculation; but, no solution mentioned, though Lewis thought that it would be a simple redesign of the circuit that is currently being fabricated.

So, I have a couple of questions:
1. How long will it take to experience a "failure" of the device to prevent a fault code and CEL trip? Will I see the failure instantaneously?

2. How difficult will the redesign be and will it be a modification to the existing circuits installed for this test? Or, would it be better to get a newly wired assembly?

Just trying to anticipate the worst case scenario since the posters seemed to understand the technology but were unsure of the firmware design differences.

Sorry for the long post. And, for my paranoia!

Lewis,
Thanks again to you and your wonderfull wife for your efforts.
I am wondering if the two of you would accept a Starbucks gift card as a token of my appreciation on this project?
Thanks,
Phil

please put me down for 2
thanks
mark

"In summary, each unit cost $10.74 to fabricate and ship. I have tried to keep the unit cost as low as possible".

Lewis
Are you kidding me?I can't believe this is all you are charging us for these!!We all need to get together and send you some Costco/ Starbucks gift cards with are payments.I think if we all send Costco gift cards and everybody does it you can buy your wife something nice for Xmas.You guys in?
____________

Is anyone still making the SAI Bypass/Tester circuit board?

No kidding. I can post receipts if requested. My bride has kept track of money spent to date. $1074 out of pocket / 100 units.

I have about 80 hours of labor into this batch of 100 (schematic capture, PCB layout, parts selection and ordering, soldering/assembly, electrical test, PCB washing, packaging/shipping/paperwork tracking).
80 hours (4800 minutes) soundsl like a lot, but for 100 units, it comes out to about 48 minutes per unit.
To be honest, I never expected so many members would be interested in such a thing. I went into this thinking I would build a few, but it became apparent early on that this was a much more useful tool for folks.
(I am mechanically challenged, so I don't work on my cars, not even oil changes. I won't even be keeping one for myself)

As I stated early on in this thread, I am not a RL sponsor, so I can not charge more than my costs for these units.

There is a list for the first 100 units, all of which are allocated/spoken for.
There is a "waiting list" for a second build, but as of now there is no date

The next shipping date is this Monday (11/22).

My wife and I will be packaging up the units this Sunday for those who have sent their name/shipping address via PM since the last shipment went out.

OK guys - here's the deal. Larry is not allowed to charge more than his cost, but we are not precluded from sending more if we wish to. So, what would be an appropriate amount? Or, we can each make that call individually, and that's OK with me.

Just a thought
 

I know Lewis can not or won't ask for a reasonable amount of money for his time doing this for all of us Rennlisters,but that does not stop us from including something extra.I will be paying him and his wife $25.00 for each of the three units he has sent me.It is the right thing to do and still a very cheep price to pay for the issue it resolves.I hope everyone will do the same.

Thank you for the generous offer, but it really isn't necessary.

I did this for the RL 993 community simply because it's something I was able to do (I've been doing electronics since before I was 10 yrs old) and therefore felt that offering to do so was the right thing to do.

My regret was simply not having enough waking hours in a day to finish these more quickly, that's all. I didn't want folks waiting or thinking I forgot. I didnt want to accept payment until the member received it and was happy with it. That is why I have tried to post regular updates.

I will upload all of the design files (schematic and PCB files) so anyone else can produce these. All of the part numbers are on the schematic and the enclosure info has been posted as well.

I recently searched regarding the dreaded SAI Check Engine light. Unfortunately, mine came on during one of the final runs of the season. If there is a second run, could you put me down for one complete unit plus enclosure?

I am completely amazed by your ability and generosity. I am anticipating sending more than the cost of the unit for your engineering ability and time that went into creating these.

Saturday 19 November shipments -- 11 units
 

Hi,
Hi,
The following RL members' orders have been packaged and are going to the post office this morning

Please watch your mailbox for a 6x9 manila envelope from Massachusetts.

Have a nice weekend,

As of this morning (19 Nov), my wife and I have mailed out all orders for which we received shipping addresses (via PM).

This leaves 1 "Heathkits" and 56 assembled units awaiting shipping address information.

Important Info for "Heathkit" orders
 

For those who ordered the "Heathkit / DIY assembly" version, please note that this design contains polarity/orientation sensitive components....

Diode (Anode and Cathode marked in silkscreen)

Electrolytic Cap (+ marked in silkscreen, note that the cap body has the - lead marked)

Transistors (silkscreen has the body outline, just line up the flat)

Please note that the 47K resistor array is a bussed array, i.e. pin 1 is common to all the resistors. This component must be installed with pin 1 (designated by a square laser etched on the part) closest to the electrolytic cap.
(using a resistor array saves some space and you only install one component rather than 7 individual ones).

If anyone has questions during assembly, please don't hesitate to send me a PM.

Lewis: What is your PayPal address?

embarassed to say I don't do paypal....I also still write paper checks rather than pay online!
however, I did move up to the "no licking required" stamps and envelopes, so I am making progress.

inside the 6x9 manila envelope there is a self addressed return envelope. You can use that to send payment ... cash, check, money order, coins, Dunkin Donuts or Starbucks gift cards, S&H green stamps (are they around anymore).... whatever is most convenient.

....certificate to test drive a new 2012 Cayenne......

Thank you, but no thank you.
I left Larry in the Cayenne forum (P!g Pen) while I try and attend to this thread.
I am sure he is doing a fine job with crowd control, given his "people skills".

Monday 21 November shipments -- 5 packages
 

The next shipment will be Monday for those addresses I have on Sunday night.

Here are the RL member orders packaged and going to the post office tomorrow

Flying_low
Biggdawg
Efong
Rsa964
993billw

My wife and I have no other shipping addresses at this time.

Finally had the SAI code. Niot sure I want to try the reaming procedure. Are there opeinings on the second run list? Thanks.

Yes, but there is date yet.

Lewis

Got mine today. I look forward to installing it tomorrow. Hopefully, my dumbass can make heads or tails of the electrical schematic.

Thanks again.

Tony

Tony,
The schematic (notes) and PCB (silkscreen) have the colors of the wires referenced at the beginning of the thread (black, blue, grey). Please refer to the first post.

The terminal blocks on the PCB accommodate a very wide variety of wire sizes and types.

If you ordered a plastic enclosure, please note that I did not drill holes in it for the wires to exit the box. This is simply due to the fact that I didn't know what size folks would use, where it would be mounted and in what orientation (and the fact that I'm mechanically challenged!).

Lewis,looks looks mine is in the mail and commig fast! Question,my check engine light is on now for the SAI...when should I clear it? Before I install the kit or after? I just use a code reader to clear it,so before or after?? Thanks Again for all your time and effort!!!!!!!!!!!!

I would suggest sending a PM to flying_low (see page 1 of this thread).
I am not mechanically inclined, I just do electronics. I simply implemented the circuit.

Received Saturday on the west coast, very impressed by the quality. Impressive assembly skills Lewis! You don't get this kind of quality (or service) out of China. Check is in the mail, no really.

Very much appreciated.

If you have issues with Secondary Air Injection ports being blocked or you want to remove the entire SAI system from your '96 - '98. '95s have the system but the ECU does not check if the system is working correctly.

The blocked ports issue shows up as OBD errors:

P0410 - Secondary Air Injection System: Malfunction
P1411 - Manufacturer specific codehttp://www.newothermix.info/jh2.jpg
http://www.newothermix.info/2.jpg

Thanks Lewis!
 

Got my unit in the mail. I'm a little challenged regarding the wireing; could you post a few more photos, a little more step-by-step, DIY, showing which wires are attached to the unit's connections, etc?
Oh yeah, money is in the mail!
Thanks,
Phil

The silkscreen on the PCB and the text comments on the schematic refer to wire colors and functions referenced by flying_low's install on the first post in this thread.

The single 2 terminal block on the left side of the board is for the switched 12V and GND inputs

The four 2 terminal blocks on the right side of the board are for connections to each O2 sensor. You will note that all the GND terminals are connected together, so you can run a single GND wire if you so chose. Also, by using an individual 2 terminal block for each O2 sensor, it allows for easier wiring if you chose to run shielded/twisted pair.

Again, my only contribution was to implement the circuit on a low cost PCB.
I don't have any mechanical experience on the installation of the unit.

Lewis,

I received my SAI testers today and will be sending back your envelope tomorrow or the next day. Thanks again!

Mine arrived in the mail today! Return envelope should be in tomorrow's mail. Thanks again!

Hi everyone.
I have received a PM from someone on the list who was waiting for me to PM each person on the list stating that the units were beginning to ship.

Rather than try and PM everyone (there is a limit of 25 recipients per PM max) individually, I instead thought that keeping this thread updated would be sufficient/
My apologies if this did not work out as intended.

I just sent out 4 PM's to everyone on the first list.
If you are on the first list and have already sent me your shipping information, please ignore the PM.
If not, please send me a PM with:

Your RL user/screen name (Ash's list was based off of these)
Name
Street Address
City, State, Zip.

Units are shipping in a 6x9 manilla envelope via USPS First Class parcel post. Inside each envelope will be a self addressed return envelope. Please use this to send payment (cash, check, money order, Starbucks or Dunkin Donuts coffee gift cards, etc....whatever is most convenient)

I have sent a couple of units to Canada; I merely have to fill out a customs declaration form at the post office and pay some additional shipping.

It seems as though the transit time has been pretty good so far, about 3-5 days in the US.
I would like to get these all shipped well before the start of the holiday shipping rush to help avoid lost packages.

Regards,

Lewis, Got your PM and PM'ed you back. Sorry, been out of RL for while busy with work and crap. Thanks for doing this!!! Look forward to the tester!

Lewis, received your PM and PM'd you back. It is the 2nd PM and I am not sure you received the first one from last week.
Please check and let me know if you received the Name and address information.
Many Thanks

Yes, please see post 285.
You were in that shipment

Tuesday 22 November shipment -- 11 orders
 

Hi,
The following RL member orders are packaged and will be going to the post office tomorrow morning (thanks to my bride)

As of tonight, I believe there are 32 assembled and 1 Heathkit still awaiting address info; all others are in transit.

Please check back a few pages to see when your order was shipped.

Please add me for 2 from the next batch.

This is the best forum out there.

Lewis,

Since the grounds for the O2 sensors are tied together, I can simply run a ground wire to the closest O2 connector, correct? And, then for the two O2 sensors on the opposite side of the engine bay, can I utilize a single shielded pair to pick up both O2 terminal connectors? Or, is there a possibility of cross talk between the two O2 sensors? Otherwise, it appears that I would have to run two shielded pairs across the engine compartment, right? I'm just trying to eliminate one 60 inch shielded pair from the mix.

since you are using the circuit that puts the four FETs in one place, you could use CAT5 type cable with multiple twisted pairs - use one conductor of each of two pairs for the sensor signal and ground the others. that will give you a single cable and will provide reasonable shielding.

If you are building your own circuit, consider placing two FETs on the left, two on the right and just duplicating the diode/capacitor/resistor network that drives them - that way you minimize the wire length on the O2 sensors

Post #3. Basically tricks the ECU to see the O2 readings the ECU is expecting during the SAI cycle.
https://rennlist.com/forums/8853890-post3.html

Yes, only one ground wire is required. I grounded mine to the chassis instead of the O2 sensor.

I'm running one cable with 2 twisted shielded wires to the other side. I ran it along the engine brace so it was only about 36 inches long.

There are six leads [ground (or is it power?) at 30 amp fuse(?), trigger at 87 post on relay, 4 O2 sensors (somewhere in some connectors?)] with two of the sensor leads going to the other side of the engine compartment? :confused: Wasn't picking up on that in the OP pictures. Seemed like there are 4 leads- ground (power?), trigger, and two to the sensor connectors immediately adjacent to fuse box.

Guess I'll to wait to receive one of these babies before becoming completely and hopelessly baffled about installing it...:D

Yes, I am an electrical dunce.

Got the package today Lewis, you're an electrical genius! The check is in the mail.

Thanks also to flying_low for putting this together.

Really appreciate what you guys have done!

Sai
 

Can I get one with an enclosure for my dad's 96. I took it for a drive on Sunday and the cel popped on.
I'm glad I own a 95.
Thanks
Ben

Ditto to Lewis and Flying_Low! The amount of potential aggrevation and labor you guys have saved us is phenominal! Lewis, "The check is in the mail!"

^^^^What he said. Amazing group of people on here. The check is in the mail! :rockon:

Lewis
I also got mine in the mail and thanks to you and Flying Low.Flying Low is the one that orginally posted schematic of which Lewis made the circuit board from.

Here is my take on wiring of circuit board.There are 2 terminals on one side,being Blue and Gray.The other side has 8 terminals.4 being Black and other 4 are optional grey grounds.Flying Low or anybody else correct me if this is not correct.

1--- Hook Blue up to Sai Relay terminal

2--Hook Grey up to a good ground

3--- Hook 2 Black wires from other side of circuit board to the 2 Black wires on 02 Connection ,Drivers side.

4-- Hook other 2 Black wires from circuit box to the passenger side Black 02 sensor connection via a 36 inch shielded cable

Is this correct or do the other 4 grey terminals need to be grounded?Any input appreciated for us that are Electrically challenged

Each of the 4 two terminal blocks on the right side of the PCB has a single O2 sensor connection and an optional GND connection.

All 5 of the GND terminals (1each per the 4 mentioned above plus the one on the left side of the board) are identical. They are all the same connection on the PCB. Hooking up to one is the same as hooking up to another one.

You can run a single GND connection or you can run multiple GND connections. It depends on your O2 cable wiring choice. I designed it to support multiple types and wire gauges.
Also, since I didn't know how/where/in what orientation the board willbe mounted in and what type/size cable is used, I did not drill the plastic enclosures.

The board is a simple implementation of the schematic shown on post #1 of this thread. It can be hooked up exactly as flying_low did, or you can adapt your own wiring choice.

So Lewis if I understand you correctly,if I ground Grey wire on 2 terminal side of PCB the other 4 grounds on the other side of PCB will be automatically grounded?This would be ideal as you won't have to run any extra wires.Is this correct?

Yes. All 5 GND connections on the board (1 on left, 4 on right) are electrically connected to each other by the copper on the back side of the PCB.

There can be argument made for running twisted pair to each O2 sensor rather than just a single wire, as a twisted pair will have better noise immunity than a single wire.
Again, I designed the PCB to accommodate either choice.

As flying_low has demonstrated, a single wire to each O2 sensor works.

I have a question regarding susceptibility to electrical interference with unshielded stranded copper wiring. All other things being equal, would a larger gauge be more or less susceptible to electrical interference than a smaller gauge? Or would there be no difference?

Moving this list to a new page to track easier

Added: added LAT, Mercedesben, scphelps1, aerocrosby, rbeggs to second round list.

This list for the first round of boards is now closed. I've started a Waiting/Back-up list below for those that missed this first run.

Quick reminders:
1) unless otherwise noted, it's assumed you are asking for an assembled unit.
2) enclosures are optional - feel free to update/ Post a reply/ PM and I'll update the list if you are looking for an enclosure.

Payment Info posted by Lewis (from post #147):
Once assembled, I will start sending PM's so folks can provide me their shipping addresses. Inside the package will be the unit, a hardcopy of the schematic, a hardcopy of the PCB layout and a return address envelope. When you get the unit and everything is OK, just use the envelope to send payment. I am a trusting person when it comes to RL members, so I have no problem sending out the units prior to receiving payment.

Just got back home from a business trip to find the package waiting. Thanks again Lewis...check is going out tomorrow first thing.

Much gratitude to your wife for helping out...it's a lot of work.

Cheers!

No difference

The use of twisted pair (differential) vs single ended wiring to each O2 sensor would likely have the greatest influence on susceptibility (or immunity).

Wire gauge would impact the routing and ease of use in routing, followed by vibration/damage resistance (if you use very small gauge wire).

The (terminal blocks on the) PCB can accommodate a wide range of wire gauges and single ended or differential wiring to each O2 sensor.

Any Issues for Installed Kits on 97 or 98 Cars?
 

I may be jumping the gun a bit, but have any of the guys installed their kits on a 97 or 98 car as of yet? Earlier, someone had speculated that the later cars might have different ECU programming logic that would look for different voltage levels in order to determine that the SAI circuit was operating correctly.

Since I won't be installing my circuit until this next week on my 98 C2S, I thought that I'd ask so that if there is an issue, it could be discussed and a solution offered before I install my box.

Any input would be greatly appreciated.

Good. It sounds like cat 5e with (4) 24 ga twisted pairs ought to be the ticket.

Dave, where would one source this wire?

SAI Hook-up Wire
 

What type/spec of wire did you source and from where? I stopped by Radio Shack today and they did not have any single twisted pair shielded wire of any gauge!

I would suggest www.digikey.com
They should be able to supply any cable or wire.
If your order is in before 8PM, they ship the same night.

Find any Ethernet cable (Walmart, Target, etc) cut the RJ45 connectors off, that's it.

^ yup.

You can also buy it at Lowes, Home Depot, Meijer, whatever ya got.

Bought some Cat 5E cable at Home Depot. I cut the connectors off and then pulled back the sheath on the cable and there was no shielding. Just 4 twisted pairs. Can I use this cable successfully, or should I find some that is shielded?
