If I were going to do anything like this not that i would LOL.. :>) You might do it a couple of different ways. First is easiest. Put a 3 axis accelerometer along with a micro processor in the box that hooks to the msd. Read rpm, g's and calculate rate of rpm rise. From there you can have the track mapped in memory for limits on rpm rate of rise vs g's lateral and longitudinal. The second tougher way but not much tougher would be to have wheel speed sensors in some innocuous place like the brake caliper with a wireless network broadcasting data to the box and add that data to the equation. you limit slip with the rev limiter or by controlling ignition timing. I still like the cell phone interface, thinking way outside the box. Reminds me of the garage door opener to run the nitrous hidden in the frame rail :>)...
