Repair & Return Process

    The Repair and return process is pretty simple and helps you avoid paying the high cost of a new ECU through your dealer.
  • Step 1: Click on the buy it now button, select your return shipping preference and complete checkout. (Please make sure to read the Tech Notes below prior to purchase, thanks!)
  • Step 2: Package your ECU carefully so that it does not incur structural damage during shipment. Take it to the Post Office, FedEx, DHL or UPS and ship it to:

    Your Part Source

    (Please make sure to include a note detailing the issues your vehicle is having and any trouble codes the vehicle is throwing. Make sure to include a contact number which we will only use if we run into an issues with the repair.)
  • Step 3: The ECU arrives for repairs! We will repair your ECU the same or next business day and ship it back to you promptly. We ship on Saturdays!!
  • Step 4: Since this is your computer it will return repaired, cleaned and ready for plug and play installation! It's that simple!

Tech Notes

  • Not all issues with your ECM can be repaired. Please contact us before purchasing the service and provide us with the issues and trouble codes so we can review and make sure there is a good chance the ecu can be repaired.
  • 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.


  • This repair carries a Limited Lifetime Warranty!
  • You will receive a detail of the repairs that took place. Those repairs are covered for Life! You may also receive install notes detailing what you may need to repair or verify good prior to installing the repaired ECU. If it is determined those repairs did not take place and the same component(s) are blown it will not be covered under the warranty. In all cases where there is an issue rest assured we will work with you to get your vehicle up and running.
