I have one of Andy's later 3-piece manifolds supporting an intercooler and Autorotor pump. You can take a tach signal off of the diagnostic plug in the passenger's foot-well (thanks John), but there's no easy way to get an injector signal without tapping into the injector harness at the engine.

If you have the Shark Tuner, John is considering an upgrade that will take the serial digital data from the Innovate system and import it into his software. This would be great for logging so that you don't need two lap tops running at once.

I'm deferring to Tony for suggestions for temperature probe placement since he's already done it.

These are K-type thermocouples available from omega engineering.

You will need extensions from them to reach the cab. Small pilot holes were drilled where need to pass the TC wire through. It was then sealed and or secured down with the Right stuff sealant. I used tape to mask around the area so i didnt get the sealant all over the place...it can be a PITA to work with.

in each instance the tip of the TC probe doesn NOT touch metal. The tip is bent away from the surface and into the airstream.

T-1 is Intercooler discharge at the bottom of the manifold.
T2 is Supercharger discharge before the intercooler.
T3 is Supercharger inlet
T4 is Airfilter

You can see on the TC meter that each location is selectable. It also has a MAX hold feature as well as T1-T4 ...T1-T3...T1-T2...etc..
This feature allows you to see the drop/change from T1 to whatever you select..Intercooler in VS out for example.

I may get this device next ...


it hooks up to my Aux box and LM-1 and will log 4 channels of temperature. I already have the probes installed so i just have to plug it all in.

Wow! That's great Tony. I guess I won't be Tcoupling my setup until I find a good reason to pull it all apart. Thanks for the pics!

I had a vacation day to burn today, so I decided to put it to good use. I finally got the Aux Box hooked up and my replacement WBO2 sensor. It took me a whle to get it to read correctly on the log works, and what kept messing me up was that my digital gage seems to be flaking out - which is what I was trusting as being accurate. I'll dive into that one another day.

Anyway, as of now I can log AFR, Boost, and RPM. I might play with thermocouples later, or I might try to log injector duty cycle.

Here s 3'rd gear pull. Looks like I'm just hitting 8psi boost! It also looks like it's leaning out just a tad near redline. Will ned to lok at that more carefuly.

All-in-all not bad for an afternoon's work.

P.S. Just noticed that Tony started this thread two years ago!

Stock fuel pump and 30# injectors?

2yrs! where does the time and the $$$$ go!

AO

Yep. Stock and 30#. I might have to bump up the fuel presssure to address the top end, but since I'm already very rich on the bottom end under the cruise map, I don't knwo if I want it any richer. I'm not sure if the Shark Tuner can adjust the cruise map enough to compensate... but that's another thread.

Hello Andrew,
Do you mean that it is too rich at WOT on the cruise map ? Other than at WOT you should be operating on the O2 loop, and the A/F will be 14.7:1.

If you mean WOT on the cruise map, then of course it is possible to optimise this with the ST, no problem.

Similarly you would be able to optimse the fuelling at WOT, you need to check whether you are at >95% on the injector duty cycle. Only if >95% would you need to increase the fuel pressure.

Do you think you are now making more boost than when DR SharkTuned your car ? I know you had suspected belt slip (pulley issue) Higher boost might explain why the fuelling requires remapping at the top end.

AO

John,
Thanks for jumping in on this. Now I need to think this through a bit more carefully, becasue your questions make me think I may have mis-spoken. And my confusion maybe fed with my inaccurate AFR gage in the car.

At cruise, AFR is good. Somewhere near 14.7 +/-. When I give it WOT, it goes quite rich - 11.x, then recovers. This is the point that I'm thinking of. If I increase the fuel pressure, I may be getting down into the 10's - which I think is less than optimal, but if that's what I have to do, then I'll do it. Looks like I should probably also set up the Aux Box for logging the injector duty cycle.

And to answer your question, I beleive I am making a little more boost than before and this could be the reason for the slight lean-ness. Unfortunately, I have no data to confirm this. The SC pulley has been slightly modified - but that was in response to an issue that appears to be resolved now.

Maybe Santa could bring me a Shark Tuner? Are you feeling generous? I've been really good this year!

John Speake

Hello Andrew
OK, if you are reading 14.7 at cruise, then there's not much wrong with your A/F meter.

Don't confuse "transient enrichment" when you stamp the throttle with the mapped values (steady state)

The LH is programmed to give a transient enrichment when you stab the throttle, otherwise there would be a instantaneous lean out and hesitation. So an over richness (which can last a couple of seconds) is normal. The mapped values are probably OK, as DR set them up.

(You can also remap the amount of transient enrichment, and its period with the SharkTuner)

You can best test the steady state by starting from 1000rpm in 5th gear hit WOT, and datalogging the result. As acceleration will be (relatively) slow, you should record the steadier state fuelling up the rev range.

I don't know if Santa will get to MI this Xmas.... best to order a ST so you aren't disappointed :-)

AO

OK, I now have the Aux Box set up for injector duty cycle. (Thanks again Tony! ) I probably won't be able to get out and do any runs until after Christmas, but I'll post as soon as I have something worth posting.

Andrew: Your new avitar is, uh, well, disturbing, but I get it.

AO

I'm bored... wifey gone... have camera...

AO

Got a question here for all y'all. I was reading the innovate forums earlier and there was a guy hooking up his Aux Box to log his vehicle speed. I thought this might be a fun thing for 0-60 times and correlating with the G-Tech.

It looks to me that we could tap the EZK on pins #23 & #6. Just curious if anyone has done this before?

John Speake

Hi Andrew,
No, sorry, that's the engine speed (flywheel) sensor. You might have more success with looking at the PDS ECU inputs....

AO

I'm sorry... PDS? Do you mean PSD?
