If your truck or van is experiencing any of the following, a failing ECM is the likely culprit:
- Complete no-start or intermittent starting condition
- Rough idle or engine stalling unexpectedly

Expert Insight: The Importance of a VIN-Matched Module
On a modern Duramax diesel, the ECM manages dozens of critical systems—from fuel injection timing and turbo boost to transmission commands and emissions equipment. Unlike a simple sensor, you can’t just swap in a used ECM from another truck. Each module is coded with a unique VIN and specific operational software. Using an incorrect or non-programmed module will, at best, result in a no-start condition and, at worst, risk damage to other expensive electronic components. Our service takes all that risk away. We handle the complex programming, so you receive a part that is truly ready to install, making this the smartest and safest fix for your vehicle.
Don’t let a bad computer keep your essential vehicle sidelined. Get the right part, programmed correctly, and get back to work with confidence. This Programmed 6.6L Duramax ECM is the reliable heart your truck needs.
Frequently Asked Questions
How do I provide you with my VIN?
After you complete your purchase, you can add your VIN to the order notes or reply to your order confirmation email. We cannot ship your part until we have the VIN to program it correctly.
Will I need to do any additional programming after installation?
In most cases, no. The unit is shipped ready for installation. Some vehicles may require a simple security relearn procedure (often called a Passlock or anti-theft relearn), which can be done without special tools and typically takes about 30 minutes. We can provide instructions for this process.
Is this the correct ECM for my truck?
This module fits the 2007-2010 GM trucks and vans with the 6.6L LMM Duramax engine listed in the compatibility chart. The best way to ensure 100% compatibility is to provide us with your VIN during checkout. We will verify the fitment for you.
Why is this better than buying a used ECM from a junkyard?
A used ECM from another vehicle will not work in your truck without being reprogrammed, a service dealers charge hundreds for. Furthermore, our modules are loaded with the latest GM software updates for optimal performance and reliability, something a used part will not have.
What if I have a problem after installation?
We are here to help. Contact us immediately if you encounter any issues. This unit is backed by our one-year replacement warranty, giving you protection and peace of mind with your purchase.
