Im pissing around with holdens alot currently a VY commodore just an ecotec, ive just bought a spare ECU to fault find an issue i get when the engines cold.
I need to either pair it to my BCM or just turn off VATS anyone know the ins and outs. Yes theres stuff on the internet but its information in an unformatted mess of opinions usually.
Wanting a step by step from someone who knows what they're doing to get me started and understanding what im trying to do. I do own the required lead to talk to the ecu via the OBD port and some software.
Any takers?
