Restore Peak Performance to Your Chevrolet Impala
Is your 2008 or 2009 Impala suffering from a persistent check engine light, rough idling, stalling, or poor fuel economy?

This professionally programmed 2008-2009 Impala Engine Control Module is the definitive, hassle-free solution to restore your car’s reliability and driveability.

Expert Insight: The Brain Behind the Brawn
As a technician, I’ve seen countless drivers chase expensive sensor and component replacements, only to find the root cause was the ECM all along. Think of the ECM as the central command center. It’s constantly processing data from dozens of sensors to control everything from fuel injection and spark timing to transmission shift points. When it fails, the signals get crossed, leading to baffling symptoms. Installing a correctly programmed 2008-2009 Impala Engine Control Module is like giving your car a clean bill of health, ensuring all systems communicate and operate exactly as the engineers intended.

No. This Engine Control Module arrives fully programmed to your vehicle’s VIN and is ready for installation. We handle all the flashing and software updates before it ships, saving you time and money.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We will provide clear instructions on how to submit it. We cannot ship your part until we have programmed it with your VIN.
Is this the correct part for my car?
This ECM fits a wide range of GM vehicles. Please check the extensive fitment list on this page and verify that your old module’s service number (e.g., 12607096) is listed as an interchangeable part. Matching by vehicle and part number is the best way to ensure compatibility.
What is involved in the installation process?
Installation typically requires basic hand tools to access and swap the module. The most critical step is to disconnect the vehicle’s battery before starting the repair to prevent electrical damage. After installation, some vehicles may require a simple security relearn procedure, which can usually be done without special tools.
What is a security relearn procedure?
This is a simple process that syncs the new ECM with your vehicle’s anti-theft system. It typically involves a sequence of turning the key in the ignition. Instructions for this procedure are widely available online for your specific vehicle or can be found in a repair manual.
