yeah, its an ecu exchange. The prob is that they are all coded to the car as i remember. I have the renaultsport ecu (mk2 cup) and the ecu, when recived from bb tuning or whoever you get it from "locks" its self to your car. you cant transfer it without having it unlocked, and thell rip you a treat for that lol! So if you wanna revert back to standard itll cost ya!
