Get Your Duramax Back on the Job, Fast.
Is your Silverado, Sierra, or Express van sidelined with frustrating engine problems?

This module is the reliable, straightforward solution to get your truck’s brain working correctly again, restoring the power and dependability you count on.

Expert Insight: The Critical Role of VIN Programming
Many people don’t realize that you can’t just swap an ECM from another truck. GM’s anti-theft system (VATS/Passlock) is tied directly to the VIN programmed into the module. An incorrect VIN will prevent the engine from starting. Our VIN programming service not only matches the ECM to your specific truck to satisfy the security system but also ensures all the correct parameters for your vehicle’s options are loaded. This is the secret to a true, hassle-free, plug-and-play repair.
Frequently Asked Questions
How does the programming process work?
It’s simple. After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We use this number to flash the ECM with the exact software and calibrations for your specific truck or van before we ship it to you.
Will I need to do any additional programming after I install it?
No. This is a complete, plug-and-play solution. Once programmed to your VIN, no further dealer or mechanic programming is necessary. In some rare cases, a crank position sensor relearn may be needed, which can be done with a capable scan tool.
Where can I find my VIN?
Your VIN can be found on your vehicle’s registration, your insurance card, or on the driver’s side of the dashboard (visible through the windshield). It is also typically on a sticker in the driver’s side door jamb.
