Finaly got a chance to do some more tuning on the traction control. If you read some of my previous posts you would know that while I had it working, it didnt really stop wheel slip just reduced the time spent slipping. My car is naturaly asspirated so controling traction is a bit more tricky than say a turbo car or nitrous car where you can just reduce the amount of power easily.
Now I went about it a whole new way, AEM didnt feel it would sound very good on the street due to popping and banging but I decided to try anyways. And all I can say is WOW.
Basicly I made it do ignition cut percentage wise when it senses slip, and it worked mirracles. Full power shift 1st to 2nd and all I get is a little rumble out of the exhaust and NO wheel spin. No popping no banging just a little rumble, and that is exactly what happens every time it senses wheel spin.
To those of you that have an AEM unit, I will be more than happy to tell you what to adjust for a good setup on radials(pilot equivalent). If you have better traction or alot more power than I can tell you what a good start is.
How would you get the AEM to limit wheel slip on a nitrous car (you indicate it is easy) any type of scheme utilizing ignition control would be catastrophic. Turbo's may be easier, not nitrous. If I'm wrong, please explain.
please explain what you mean by nitous control, that can mean many things. Just turning nitrous on can be done with a $5 WOT switch. I sincerely want to know how the AEM can apply traction control on nitrous. You cannot turn the ignition off and then on (as with a NA car) when applying nitrous. Make me a believer and I'll join the AEM movement.
Just like a nitrous controler, the AEM unit can control all functions of your nitrous.
For instance if your car breaks its tires loose the AEM unit can turn off your nitrous and pulse it back in as you regain traction. At the same time it could be adjusting timing and ignition cut to obtain traction. As traction comes back so will you power, this all happens very fast far as you know it will sound like you are just missfiring.
rwhp: its been a while since i played with an AEM... if i recall correctly last time I played with one it was using the VSS for traction control rather then wheel speed sensors? Has this changed or can it be configured to use the wheel speed sensors?

Charlie, as far as I know, the AEM does not have wheel speed sensors like the Motec and its 4-wheel traction multiplexer which I believe has a program where you load the front and rear tire diameters and allows you to tune a percentage of slippage into the rear wheels relative to the fronts. I think this is better than the AEM which basically programs how much acceleration you want. I would think the Wheel speed would be more effective allowing for more exact and consistent traction control accomodating any road/track condition, slicks/skinnies street tires. The only adjustment necessary to be right on would be automatically done by the wheel speed sensing. With the AEM, I think there is a lot more trial and error to accomodate the variable conditions I listed above. I have to say I have never even worked with any Motec anything, but this was my understanding when I read up on the Motec traction control a few years back.
i would think that the aem traction control would be a huge hassle then wouldnt it? I mean, if your only working with your VSS... if its a colder night and your making 20hp more and accelerating that much faster, isnt it going to think that your spinning the tires and then kick in traction control?
or am i forgetting something?
I dunno... i personally ditched the AEM that I had in one my cars... I never got into tuning it... so i am replacing it with one of the systems I work with.
good job bro. the AEM is the shit
Linear Mode
