Coils, injectors etc work fine with the rb20 ecu (not that i swap injectors 4 and 6 when going to the PFC so its the correct firing order).
I have a standard r33 rb25 ecu, but it didnt like idling last time i tryed. Ill give it another go tomorrow, its getting a bit late now.
Should have mentioned that is an rb25 in a r32gtst currently running rb20loom/ecu/afm.
