I have been told by my local dealer that the ECU (standard or race replacement) is programmed by the bike it is fitted to the first time the key is turned , after that it will only work on that bike
They contacted Hacket and he confirmed this as they suspected Ducati Uk were just trying to sell more ECU's every time someone bough a second hand pipe
I have heard that you can get good power output increases from a pipe using the standard ECU and a power commander
