• Question

  Where do I send my ECU to have it repaired?

  Answer

  Unfortunately we cannot repair the ECU because it is Potted. Potting the ecu provides several benefits. The down side is that a potted ECU cannot be repaired if it is damaged due to improper installation. Always read the instruction and follow proper installation procedures to avoid ECU damage. If you damage the USB port by pulling the cable out of the connector on the back of the ECU we may be able to repair it. Contact a tech service representative for more information pertaining to a damaged USB port.
