Perhaps it needed a calibration of some sort. Without a workshop manual / installation guide impossible to tell. That or it was somehow not programmed correctly / not picked properly / for the correct model.Not sure what the other ECU was supposed to do. It messed up the shift indicator and threw a code. Bike runs great now; exhaust is a deeper tone.
Unusual that from EvolutionBike, I have used them on a number of occasions and always received first class serviceI got it from evolution in Italy. They don't seem very good at shipping or filling orders properly. Hoping to find a dealer on the east coast who has knowledge of the bike.
