Are they all locked and therefore useless? Lack of power to an ECU will not lock it, no. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft" Peugeot 306 GTi-6 2000 (X), Moonstone

However, perhaps in your case there were different parameters involved and on this occasion it has contributed to it... ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft" Peugeot 306 GTi-6 2000 (X), Moonstone
