Thank you Mark.. I knew this would be a huge learning curve for me on these two subjects.. My biggest concerns on implimenting TC & ABS units that are designed for racing is the liabitiys.. I will have to have to discusss this with my customer..

Not until the Z/28 was PTM (Performance Traction Management) ie Traction Control equal to drivers best effort or in some cases better. The other thing about PTM is it is much easier to drive fast.
BTM is very complicated. It is a fully integrated system that uses the following sensors:
Throttle position
4 wheel speed sensors
4 suspension travel sensors
Lateral sensor
Longitudinal sensor
Yaw sensor
Tire Pressure Sensors
All this feeds into a predictive tire models that predicts how much power the rear tires can take. We even use the suspension travel sensors to know if the car is airborne so not to cut power when it lands (Flying Car Mode).
So can it be done? Yes. Do I use it on my Hot Rods? No.
I don't have the time or the money to calibrate it. At 875 HP the integration time takes a long time and a lot of tires.
If I had a shop and sold cars to the public. (Not that guy in Woodland that can drive high HP stuff) I would think about slip based traction control to keep people from hurting themselves. My cars can do 3rd gear roll on burn outs! The pro race teams tune the TC systems to each track so it is easy. A one sizes fits all calibration is tricky.
