Traction Control: ASR, can you modify the programming?
I noticed the traction control got better and better as the C5 came abou then the C6. Is there any way to get into the traction control on a C4 and modify it for better traction?

I use CATS Tuner, Novice here, or lets say I have it. Where is it and have you ever played with it?
I know eventually it throws on the brakes and pushes the throttle back. Would adjusting the spark retard reduce these other effects?

Lot more to it in the newer ones than just the programming. Better brake controller, faster processor, more sensors, etc

Mate if you had a 94/95 id change them for ya!! I honestly wouldnt like to guess at what sort of changes you would need to make to get it the way youll be happy with it, and again, if you had a 94/95 it would probably be alot easier to experiment with it. It might take you a few goes to get what you want from it, but if you have the ability to burn your own chips, get to and and experiment!!

I checked the ZR1 files as well and they dont seem to have anything there to adjust it either. Must be only on the $EE and later.

I'm sure it is in the older ECM's on my 96 you can adjust how much timing the ASR pulls...
i set my back about 10-15 degrees across the board as with my supercharger I was like a deer n the headlights if i punched it with the ASR on.
It worked good... on the 96 you can also have it disabled but it causes the SYS to flash.
i realize you are dealing with a different ECM but I'm sure you should be able to to do similar things with tunercat...
hope this helps,

My '94 has that parameter as well. In the switch constants, there is a check box for traction control. Even with this set to disabled, the asr still works, it just doesn't retard the timing during an asr event. In other words, it just works the throttle relaxer and brakes harder until it gets the desired results.

I wish there was a way to do away with the kick in the foot and just cut back the power via retarding the timing. If you unplug the ASR box under the hood and remove the ASR diagnostic code would you have the situation where you don't have the pedal kick but the timing is still retarted.
