what you are forgetting/dont know is that this ecu has been around for a long long time m8, and used in way more applications than you could even believe, ducati Vtwin motorbike, ferrarri F series and many many more , there fore it has teh ability to lend its hand to many differant types of ignition/injection types, its just knowing how to acces/make use of what its got, and yes there are many revisions of the same type, its a case of whether the person who maps your car knows what there doing with it. alot of the times that the differant functions are put on to the ecu are via a basic intercetion board which will change the signals accordingly on the way out of the eeprom not making use of whats already in the eeprom/os
alot of people dont believe that i have so many of teh functions on a std board without and extra boards, but tbh my mapper has spent a hell of a lot of time researching/trialing experimenting on the things i have to make sure a, they do actual do what t here supposed to do, and b, more important to me is that there reliable
