Hi Longboard
You probably remember seeing this in a JB discussion and it's correct for them. Probably related to messing with the wiring on a live processor. For Cobb, it's the opposite. Key in, car in accessory mod ( all systems go except engine). So much drain they recommend a charger to ensure you don't undervolt in the middle of the operation
Thanks for encouraging ME to
before I try again after the dealer repair,.
