AU ecu compared to EF, talking aftermarketchip compatiability

Hey all, not sure were this should be located, in the blower section or here, but anyways...

I got an EF XR I6 engine in my EA including all wiring looms, EECV etc etc (so just pretend it's an EF XR6 for this discussion). Just recently I have bought a CAPA stage 2 powerdyne kit designed for an AU. I've rang CAPA, and they said that the only difference between the EF kit and AU kit is the piggy back chip that is plugged into the ECU and supplied with the kit. I've looked at my ECU, and the AU chip they've supplied can be inserted into it.

My question is whether I will be able to use this AU chip on the EF ECU. They are both EECV, and from my knowledge, the only difference between the two ECU's is the fuel mapping (which the chip would alter to suit the new setup anyway). My understanding is somewhat limited, so i'm hoping someone can tell me what's the go with these chips :)

Thanx in advance

Re: AU ecu compared to EF, talking aftermarketchip compatiability

There will probably be fair differences in the fuel mapping and timing curves between the AU and EF EEC's. The CAPA chips alter the original EEC programming by just adding or removing fuel/timing at certain points in there range, but it still relies on the factory maps. Supercharged engines need good tuning so either get the chip reprogrammed if it is possible with that chip (I think CAPA charge $250 for that) or install a unichip or similar.
