does anyone know if you can fit ECU's with a different 4-letter code on the tag? mine got shorted out (by me) so i bought one off some twat on the rs2000-16v forum who said he had the right one for me, but its turned up and the code is AFAR (mine was FALL, i did tell him this), and it says 4wd on it, mine is 2wd! iv plugged it in anyway and the car is still dead on the key, if you power up fuel pump and ignition relays manually the starter turns but the injectors dont fire (grounds arent pulsing)
