.... Unless ECU somehow recoginzes DISA motors and switches the algorithm....
I think that it is possible that the ECU may recognize them and adjust, but I don't think that there is concrete evidence to prove that.. When C gets his dynos, we will know more.. I am curious as anybody to how much HP can be gained from adding the 3 stage without tune.. I hope C drives it a bit before the dynos to allow the ECU to adjust fully... (If it adjusts at all?)
