Restore Peak Performance to Your Vehicle
Is your vehicle suffering from frustrating and unpredictable issues like a persistent check engine light, rough idling, stalling, or a no-start condition? These are classic signs of a failing Engine Control Module (ECM), the brain of your vehicle’s engine. This VIN-programmed ECM is the definitive solution to restore your car’s original performance, fuel efficiency, and reliability. We take the guesswork out of the repair by flashing the module with the latest GM software updates, specifically matched to your vehicle’s VIN before it ships. This ensures a seamless installation and gets you back on the road with confidence.
Common Symptoms & Your Solution
A faulty ECM can cause a cascade of problems that can be difficult to diagnose. If you’re experiencing any of the following, this module is your solution:
- Erratic engine performance, including misfires and hesitation
- Drastic decrease in fuel economy
- Difficulty starting the engine or complete failure to start
- Check Engine Light (CEL) illumination with communication error codes (e.g., P0601, P0606)
- Transmission shifting problems or harsh engagement
- Stalling for no apparent reason
By replacing your old module with this precisely programmed unit, you are directly addressing the root cause of these issues and restoring the complex systems your vehicle relies on.

An Expert’s Note on Programming
As a technician with over two decades of experience, I’ve seen countless issues arise from improperly matched control modules. A generic, non-programmed ECM from a salvage yard might seem like a bargain, but it can lead to a vehicle that won’t start, incorrect engine parameters, and even damage to other electronic components. The VIN-specific programming we perform isn’t just a convenience—it’s a critical step that aligns the module with your vehicle’s unique engine, transmission, and options package. This process ensures every sensor and actuator communicates correctly, just as the manufacturer intended.
Frequently Asked Questions
What do I need to do after I purchase?
After you complete your purchase, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship your ECM without it. You can typically find your VIN on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield.
Is this part difficult to install?
The physical installation is generally straightforward for someone with basic mechanical skills. It involves disconnecting the battery, unplugging the electrical connectors from the old ECM, unbolting it, and then installing the new one in the reverse order. However, some vehicles may require a security or crankshaft position sensor relearn procedure after installation, which can be performed with a capable scan tool.
Will this fix my check engine light?
If the check engine light and associated diagnostic trouble codes (DTCs) are caused by a faulty ECM, then yes, this part will resolve the issue. We highly recommend having a professional diagnosis performed to confirm the ECM is the point of failure before ordering.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part. Each unit is verified for full functionality before being programmed and shipped, providing you with a reliable and cost-effective alternative to a brand-new dealership part.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers the part itself in the event of failure within one year from the date of purchase. Please consult our full warranty policy for complete details.
