Seems like it is complicating something that is otherwise very simple. My guess is that it will lead to driveability issues.

Do you have a ESC installed on your car currently?


I don't have an ESC, but I have been considering it. One of the holdups for me is the lack of proportional control which would become an issue during autox, I'm quite certain of it. This post elaborates a bit on my concern: http://www.ft86club.com/forums/showp...postcount=4142


What this idea is trying to accomplish is to provide some modulation of engine torque after the ESC is engaged so you can balance the car with the throttle. This is shown via the manifold pressure line on the plots I posted. I completely realize that there would be more to this than just a modification of the drive by wire tables. I also expect the hysteresis of the pedal switch to be a bit of an issue. That being said, it's just an idea of mine that I've been kicking around for awhile.


The ultimate solution is proportional boost control via ESC speed control. ESC engagement could still happen at 50 or 75% throttle position, but the boost, thereafter, be proportional with throttle position.
