Hello good peopel i have a Porsche 996 that i have buyed previous owner has engine swapped it from the ordinary 3,4liter to a 2007modell 3,8l with engine code:M97/0168715829. It is a non turbo. Thing is that he keeept original brain from the 3,4liter... So some how i need to get the original file from the 3,8 liter into this ecu. The ecu is a M5.2.2 BOSCH. Is there anyone here that have done that before or know exactly how to do it ? I have the read for the ECU here. If anyone know for sure how to do it il pay if we can make it work. Thanks in advance.
