ECU Programming Service for GM E98 Diesel Engine Control Unit

Please note: You may need to clear the codes when reinstalling for full functionality. If this step is skipped, immobilizer codes from before the service was completed may still keep the car from starting. We do our best to delete them before being shipped out but please double check upon re-installation. We have to open the units, this will void ANY warranty you currently have on your unit. When you purchase our service and send us the unit, you are giving us permission to open the unit. Please make sure the unit is properly packaged, so it does not get damaged while being shipped. Shipping is very harsh on electronics so be diligent.  As soon as we receive your unit it takes about 24 hours to complete the service and ship back out. Most of the time we can ship it the same day but we give ourselves a bit of a grace period. If an issue arises, we will contact you immediately. We recommend USPS Priority padded flat rate shipping. It’s the fastest shipping with the added benefit of being the lowest priced. We also receive all USPS deliveries early in the day so you have a better chance of getting your unit shipped back out the same day.

Please make sure to verify that this is definitely the service you need as we offer absolutely no refunds/cancellations on our service, at any time, for any reason. Shipping: Buyer pays for shipping of the unit to us and we will pay for return shipping via USPS Priority Mail. Please package the unit well, to ensure that the package is not damaged in shipping. We do not hold any responsibility for units damaged in shipping to us. Arrival time expectations: Regular priority shipping: 2-3 days. Priority Express shipping: 1-2 days. Any signature confirmation could delay delivery.
