Hello guys, planning to buy a 130HP 1.9PD engine with everything from A6 C5, or B6 whatever.

My question is: What can I do with my ECU? I have an AJM PD engine right now, but this ECU seems really dumb compared to the 130HP engines. Can I copy my program to a B6 ECU, or can I remap my B5 ECU so it will notice the same thing in the engine as the B6 ECU?
