When I bought my latest impreza the garage I bought it from did not know that much about it, it has some paperwork and receipts in a folder for some of the modified bits, there is nothing to say wether the car has been mapped or not, I just presume it has because it has been fully de-catted and has a k&n appollo induction kit, what would be the best way to find out if it has been mapped, who buy and what software was used either open source or ecutek.
