Regarding the traction control argument, the rulebook does say that the wiring harness and Engine Control Unit may be replaced with parts of unrestricted origin. I suppose we could get into a semantics debate about whether or not adding on a black-box traction control unit (or a PCIII for that matter) is allowed because you aren't replacing the ECU, you're supplementing it. If my memory serves me right (hey, sometimes it does) the intent of the rule was to allow aftermarket stuff to be added, in addition to no longer requiring stock ECU's once it was demonstrated that it was difficult or impossible to prove that a stock appearing ECU hadn't been internally reprogrammed.

Something else to be addressed this fall?
