Armand, when u fitted the ECU, did u remove the EFI fuse for 10/15 mins? if not, do this, and try her again. remove the small EFI fuse in the engine bay fuse box, let her sit (switched off of course) for 10 15, plug the fuse back in, switch her on and let her idle to warm up, then start driving her, dont nail the shit out of her right away but give her some beans for a few pulls, then start giving her full throttle in 3rd and 4th. there is no science in my explanation, i am not a mechanic, but thats how Jay and I set up my Blitz ECU at the weekend there.
