I received the below e-mail today. I had an SMT5 that quit working and I never felt like dropping the cash to replace it - no warranty on them. But, I understand the 6 is compatible with the wiring harness from the 5 (Sound right Louie?). So if anyone has an interest in the below offer (USA Please) all I would need is the SMT6 itself. The extra wiring harness, shorting plug and data cable would be yours to keep. If the price is right, perhaps we could split the cost? Any interest?

To apply for the SMT6 BUDDY KIT Special, you will need to visit the
www.perfectpower.com website and complete the voucher details. This will
enable you to get a discount certificate, which you can present to any
Perfect Power dealer around the world. For a list of Perfect Power
dealers, please visit the Perfect Power website at www.perfectpower.com,

Exactly.

 

Hi Pete,
Yes, the SMT-6 is plug compatible with the SMT-5. That's about all that is compatible though. You need different software which is available from the Perfect Power web site, or I can email it to you.

I'm not sure what the current price is, but last batch I got they were about $386. I could check if you want. I don't price them that high though. There is an additional savings if purchasing 5 or more at a time. I'm not trying to sell something here. I'm just answering Heinrich's question regarding the price.

 

Louie, just out of curiousity... what do their stand alone units go for? I clicked through several of their listed dealers and none even mentioned the stand alones.

 

How about a group buy on these guys? I may need one for my 951 build anyway...
Get, say, 6 people interested, get a total of 50% discount, plus the quantity discount on top of that (whatever that may be)...

(Just saw mention of this on the 951 forum (cross-forum group buy from any willing vendor? Louie?))

 

If anyone wants to team up to get the two for one, then I would want one...

 

whats the advantage of this compared to the jds shark tuner?

 

I would be interested in going in with someone.

 

is PP trying to liquidate their remaining SMT6 stock (to push SMT7)? Or is the SMT6 still a big part of their sales?

 

I have a Sharktuner that I'm working with now. It's a neat unit. The SMT-6 will do ignition timing control (advance & retard) and the Sharktuner does not do that at this time. John Speake is working on an ignition control for the Sharktuner this winter so I hope there will be that feature within a few months. When the Sharktuner is able to control timing as well as fuel, then that will be the way to go. You do your tuning, burn a chip, put that in and you are set. No add on devices, or wiring changes.

As I see it you have advantages and disadvantages to each system.

The Sharktuner has an Autotune feature which makes getting mixture set pretty easy. Setting WOT mixture is still a little difficult in that you go through the RPMs so quickly that the Autotune doesn't have time to get the setting done in one or two passes. Slowing down the rate of RPM change will help by either using a steep hill, and the highest gear possible for the run. Even in 3rd you'll be doing near 100 mph which on most public roads in the US isn't a good plan to do repeatedly in the same place. You don't have to do tuning with Autotune and you could do a couple runs, say in 2nd gear, and log the results. Analyze the data, make adjustments, and do more runs. You'd have to do the same thing whether using the Sharktuner, or SMT. Using a dyno for this tuning is a better way to go.

With either SMT or Sharktuner, and using closed loop, the only mixture option is 14.7:1. If you want to change the coding on your LH to no cats and run open loop, you can set mixture to whatever you want at part throttle. That is true for either the Sharktuner, or SMT. The Sharktuner has a nice feature where you can have your LH set (coded) for closed loop, and yet force the Sharktuner to use open loop and an open loop (no cat) map. You can then tune that map for your desired mixture at both part throttle and WOT. Save both maps, burn a chip, and then use either map switching between maps by changing the coding. Either have two different plugs made up, or one plug with a switch for either closed loop or open loop. If you are runnings cats, then you have no choice but to stick with closed loop. You can accomplish both of these options with either the SMT, or Sharktuner. With the SMT, you don't burn a chip. You have two different maps you can select with a switch, but if you want open loop, the LH coding plug would have to be changed too.

The Sharktuner offers a clean way to have your car tuned by burning a new chip. The downside is that if you make another change to engine configuration, you'd have to burn another chip. The LH/MAF combination is very adaptable and I doubt anything would need done unless a major change was made such as different sized injectors, or adding forced induction. The LH will compensate in closed loop for about +/- 20% in fuel requirements and still keep to the 14.7:1 AFR. Of course somewhere in your map you may have already been close to the 20% and some change would push it over the edge where it can't compensate anymore. This is common if using large injectors and the engine will be too rich to compensate at idle. However, if you had previously tuned with the Sharktuner and got the map tuned to near zero compensation, you'd have a +/- 20% change that could be dealt with automatically (in closed loop).

The SMT can be tuned as many times as you want and different maps saved to disk file and loaded as required. The SMT-6 has a basic problem with ignition triggering on some 928s. It isn't on all cars and the symptoms are different. Perfect Power says there isn't any problem. Generally a car fitted with a SMT-6, and triggered from the crank sensor, will start a little differently and will take more crank turn before it fires. My S4 usually fires up right away, but sometimes especially when hot, can take about 5 seconds of cranking before it starts. It's never failed to start. It takes longer and some people don't like that. Triggering the SMT from the EZ-K output is more reliable, but requires splicing in to one more wire than using the crank trigger. Using the EZ-K output for SMT trigger on my car caused a slight misfire at around 5000 rpm. I don't know why and I haven't seen that on another one. Bottom line, possible ignition triggering issue with the SMT.

 

I'm not sure what they are up to Mike. I'll contact the US distributor and ask. I'd like to get an SMT-7 and try it. AFAIK, it wasn't the same as the SMT-6 and was more for cars with very odd triggering setups and/or odd firing sequence. I checked out the SMT-7 a while back and decided it wasn't worth the extra cost for one.

 

Mike,
I just called and talked to the Perfect Power USA distributor, http://www.idaautomotive.com/prices.asp, about the SMT-6 Buddy package. The SMT-6 Buddy deal is primarily for individuals, not dealers, and involves obtaining a voucher number from Perfect Power at their web site, www.perfectpower.com. Then order a SMT-6 from the USA distributor, or other country where you reside. Give the distributor your voucher number. The distributor will send you a SMT-6 and get the "extra" SMT-6 from Perfect Power in SA. When they get the SMT-6s (all in one shipment from SA) the distributor will forward yours. I would get no better price by ordering multiples than I'd normally get by ordering 5 or more at a time. If anyone wants to take advantage of this, the distributor recommended doing it soon as the number of SMT-6 units available for this program are limited. The distributor said he did not believe the SMT-6 was slated for discontinuance since it worked on many more cars than the SMT-7.

I did order an SMT-7 for myself so I could try it and see if the triggering problem I have with the SMT-6 on my car has been eliminated. The SMT-7 does have some additional features that might be useful too. They do cost more with the retail around $563 vs. $389 for the SMT-6. I do know someone who could sell for significantly less though.
