If you have a custom tune and disconnect the negative battery cable, will your car need to be retuned to restore the custom settings? Currently have FRPP cold air intake, procal tune, and FRPP dual exhaust. Not sure if disconnecting the negative battery cable will reset my engine to normal factory stock tune or not.
whenever i disconnect the battery for any reason, i always follow up with a re-entering of my custom tune and i re-calibrate the throttle by wire system.
apparently its unnecessary though... i suppose im just paranoid. haha
