Ok this is what I am trying to do.
I have a 2002 WRX AUS delivered that has some mods including an openecu tune that I would like to return to stock and have the ECU reflashed back to a standard map.
I have found someone with the software, tactrix & standard defs that will suit my car.
What I would like to know is there anything that needs to be done with the immobilizer? I don't know how all this works however I keep reading of people flashing their cars with other defs/maps and then they can't start the car because the immobilizer code was different to the one that they had.
Can you give me some info onto what I should be looking for or info I can pass onto the person that will be doing it for me as they have never done a change in maps all they do is edit their own for their cars tuning.
Any help would be great.
