Well just an update, its under 0 degrees and slippery, we just sorted the traction control map and all I can say is OMG, switch that PSM off and get the rally car experience, roughly 600hp and you can drive 100% throttle with big bangs and flames looking like a drift god, switch the PSM on and watch that smile dissapear.

We are running the AEM Infinity in my crazy racer project. Have the car running, just got it to talk to my Motec dash. I'll keep you guys posted as we make progress.

Forgot the dash pic

I have gotten the impression the 112 is still undergoing some development as well, with two other ECU under their belt I've got confidence it'll be worked out. Johnny I appreciate the link to that thread, I'll be reading it shortly!! It's good to see interest in the AEM too on this platform.mhonestly we all win with choices and competing features!

Also good to hear that the traction control is effective. I never used the AEM V1 traction control and I used the Racelogic box instead. To my surprise I found it even worked when cornering to keep the car under control. With access to 4wheels worth of ABS signals there's a great deal of things that can be done. I'd be interested in hearing more about the differences you found between the OEM PSM and the aftermarket traction control! I've only ever triggered the Porsche PSM once or twice in anything but straightline conditions and it brought things under control quickly but really scrubbed speed. When you shut off the PSM I assume it's really turned off and won't come back on like the OEM system is said to do?

Edit: Wow Johnny, just read that thread! You UK guys can really get bent out of shape! LOL Really cool to read that the O2 correction has improved so much, I'm sure the other systems are as good now. Ought to make building a VE map much easier. We tuned the old AEM psuedo VE with BoostComp and once you had a good low boost pull tuned to the A/F you desired it was simple math to do the rest. I run on the rich side, timing is where most of the power is in my experience.

this is a few yrs old but i think it will give you an idea of the proefi t/c

Im more interested in TC in corners so I dont write the car off !!!

thats the ever important driver mod needed there!

Aint it just !!!!

As a little aside, I know of a drift car that fitted a Syvecs and they got the TC so spot on anyone could drift it at a very high speed, I dont know how much smoke it could generate but it could just be floored and hold a massive drift, result the guy got banned from the championship and they look closely for any similar mods !!!!!!

I want it to put the power down out of the corners and pick up max speed down the straights for fast laps times...

I think all three systems read all 4 ABS sensors now, that means that pretty powerful traction control is possible. Systems are using gyro to detect lift and slip too, the advances in just a few years are pretty amazing honestly.

I've made a decision on a system, I've even made a purchase. Looking at what's out there now it's pretty clear it's hard to go wrong. A couple of factors came into play in my decision process. Availability of support, availability of information since I expect to tweak the tune myself, and friendliness of software all came into play. Bear in mind when I originally worked with AEM I was one of the first running it on a Supra. I learned a great deal and attended multiple levels of EFI101 training - my car was used for the training and ran flawlessly. I had a pretty good idea what was important to me and have been really impressed at just how far things have come! I didn't want to be quite the same pioneer again, not on the Metzger motor! My decision is right for me and my needs so I hope no one thinks that what I chose means I thought less of other systems.

I chatted today for over an hour with Garth from Undercover. He was able to answer all of my questions and I liked his philosophy regarding how he tunes. He asked what my goals were, modest BTW, and he didn't try to push a sale. The price that Lawerence was able to offer me was reasonable and Garth's fees for install and tuning are also reasonable IMO. Their shop is fairly local to me. I've chosen to go with a ProEFI 128. I'll be adding the flex fuel system although I've yet to see E85 here, 2x EGT, a back pressure sensor (because I'm curious), and the color CAN display and logger. I suspect I'll add more sensors as time goes on - gyro and water pressure sound interesting!

I look forward to sharing what I learn with others. This is a hobby for me and it's fun to learn. I'm a data junky always looking to optimize the car, this is a good tool to do it. I might try my hand at a half or full mile race but expect to set NO records lol.

To make things really interesting a local friend of mine looks to be choosing to go with Syveccs on his 996 so I hope to get some up close exposure to that system too! His goals exceed mine so it'll be a fun ride for sure :-)

I still need intercoolers and received advice on that, I'll install something before tuning but funds are running a little low so nothing crazy! I also need my water pipes welded at some point. If the engine comes out for that it'll get rods and headstuds. I fear the price tag and hope it's awhile before I need it! :-( I'm sure I've just jinxed myself....

Gyro to detect cornering and an ABS based traction control, maybe even a sensor to detect steering angle. The first two are possible for sure, I'm not sure how the last could be integrated but I bet there are sensors from electric steering systems that could be used.

Not surprised that folks are using these systems to improve in various race series. I know that some of the first accel based traction control systems (that I knew about) were used to prevent cavitation on drag boats and banned from drag racing (MSD). Enforcing that must have been a treat! The GT-R is a good example of what can be done. I have few illusions about my driving, I say take any advantage you can get

Yep. Even a slightly faster out of the corner speed translates into huge gains on the straights (thus lap times). The tracks this car is built for are very fast layouts (WSIR and Autoclub Fontana). Both have critical corner exits dumping on to very long straights. Race ABS into the corner and traction control out should be awesome. The GT3 Cup has race ABS (there's a huge diff between race and street ABS) and it was a HUGE advantage on corner entry but I never had traction control in the Cup… should be fun!

I know the syvecs has the facility to take data from a lateral G sensor

Motec and ProEFI can also take input from 4way G sensors. Nose lifting too much on launch? Pull timing and bring it down! I'm not sure about AEM but I'd bet it could as well. Great time to be a car guy
