On most of the failures I have seen, the box just quits working and the car won't start. I know of two boxes where the 2 step function quit. I have also seen one where the car breaks up at high rpm. The 3 boxes off my own car, just quit working.

Is that why they supply a bypass plug?
So far it is working fine, I havent seen any breakup and i shift about 6500. But hte bypass plug is int the cener console

I believe that only happens on cars equipped with the Fast systems and not stock ECM's.
