Why Buy from Us
We offer quality items backed by a great warranty. These ECMs are tested, their calibration is updated, the VIN number is programmed for you at NO extra cost if you provide it when ordering, and these ECMs are programmed to start your car. You will get the best value on these ECMs when you buy from us.
Programming
No programming is needed. We already did it for you. We’ve got you covered 😉
VIN (Vehicle Identification Number)
- When you order, we provide a form at checkout for you to enter your vehicle’s VIN.
- If you don’t provide your VIN with the order or email it within 24 hours after placing the order, we will ship the ECM without the VIN. In this case, the car will still start and will function normally, but the check engine light will be lit with the “VIN Mismatch” error code.
- We understand that mistakes do happen. If you send the wrong VIN or don’t provide one (maybe you forgot), you can send back the ECM and let us know the VIN so we can program it into the ECM. In this case, we will not charge for the service, but we will charge shipping expenses based on the carrier used (USPS or FedEx).
Identifying The Part Number
Your ECM part number is on the label at the top of the ECM, as shown below.

Before ordering, always make sure your ECM part number matches this ECM’s part number or one of the exchange part numbers listed above on this page.
