not sure, i was not there, I would have hoped they disconnected the battery. Maybe they did and it was just bad luck the ECU had an issue.Hope they remove the battery terminal when doing the welding, but for exhaust normally the welding done off the car, then just hook up to the car when ready, or yours require welding while on the car?:hmmmm:
If a suitable ECU cannot be found, can they be repaired?
Thanks
