Thanks for the replay, so writing an original file to an ecu is enough to virgin a ecu to transplant to a different car?
(will clear all codes).
First time I have done this and was under the impression that a original file is just for the running of the engine and not the immobilizers.
am i right in thinking that the mapp and the immobilizer code are stored in different places (thought immobilizer was on an eeprom mapp another chip)
I know this might be obvious to all of you but i am very new to this and a good fried of mine has just damage an ecu at his garage and I am trying to help him out
