replacing ECU

When replacing the ECU in your car what numbers on the ECU are you looking to compare?

RE: replacing ECU

Very last letter(s). All ecus can be swapped with the same engine code. If the numbers dont match, you either need a immo defeat and/or code from the org ecu. You can get more info from ross-tech.com.

RE: replacing ECU

Find someone that does but you may not need one. If you have both ecus, stick it in and find out.
