Hi! I'm new here, so please be kind.
I have a Evo IX JDM, and was wondering if it is possible to reflash with a Ralliart Evo IX JDM ecu?
I have a friend who already has a Ralliart IX ECU, so is it possible for me to backup my stock ECU, upload his to my car, and give him mine to try?
Yes I know we could also unplug the ECUs and do a physical swap, but we wanted to try this way.
Is it possible? And is it possible to find different JDM IX ECUs somewhere to try?
