hey bud,
Did you try swapping in a stk ECU? if not ive got 1 you can try.
also have you tried swapping in a PowerFC + Commander to look at your voltages?
This will help you find the source of your problem almost instantly
i wish i borrowed 1 from some1 to find my problems instead of buying 1 lol, woulda saved alot of money!
PM me if ya wanna lend the stk ecu, i could maybe even swap in my powerFC if ya need
