• We will use notes received from the customer and our state of the art vehicle simulator to put your ECU through over 25+ circuit tests. This will allow us to zero in on the issues and perform a thorough repair. After the rebuild the ECU will undergo the same tests to verify the repair! Your ECU case and pins will also be cleaned so it is ready for install when you receive it back! (Please make sure your connector is free of debris, oil, dirt etc etc so a good connection is made!)
• Please note that sometimes the damage to an engine computer is unrepairable. In instances where our techs test, diagnose and attempt a repair but are unable to bring the ecu back there will be a diagnostic fee of $94.99. The remaining portion of your initial purchase price will be refunded.
• If you contact us with your issues and trouble codes but it sounds like there is not a good chance of a successful repair we do stock tested/rebuilt ecu’s. We may have the ECU you need in stock and will go over options with you.
