Currently restoring an EFI XR3i that will be running OFAB due to the power I am aiming for (220+) I need to run injectors that are better than beiges. So I’m want to run some kind of piggyback ecu as I don’t want to butcher the old wiring loom. OFAM looked perfect to me but they don’t sell it anymore. I know it’s based on megasquirt but from my understanding you can’t run megasquirt as a piggyback. What can I do???
