James please give me an example. No matter what they do, they are limited by the LEGAL build & the mechanical porperties of the engine. Anything illegal, will not be allowed a sensor. Correct? Am I missing something? The EMS should be allowed to control no more than what the stock ECU controls now. The only thing you can do is fine tune what your engine puts out now.

Hey Dan,

There's been several examples given where a maximum accelleration rate of the crankshaft is specified, maybe it's even linked to a gear indicator, or a couple of wheel speed sensors. We're allowed to keep wheel speed sensors to keep the stock ECU's happy. I know that traction control is a non-legal function, but how do we assure that it doesn't creep in. I'm especially worried about cars with drive by wire throttle's, where throttle actuation isn't directly driver controlled. Currently WC makes these cars switch to manual throttle's, and I'd think this would be a good place to add a spec item.
