Restore Your Vehicle’s Brainpower and Performance
Is your Corvette, Sierra, or Escalade suffering from frustrating and hard-to-diagnose issues? A faulty Engine Control Module (ECM) can manifest as a no-start condition, poor fuel economy, erratic idling, or a persistent Check Engine Light that leaves you guessing.

Expert Insight: The ‘Digital Handshake’
Think of your vehicle’s ECM as its central nervous system. When you install a new one, it needs to perform a ‘digital handshake’ with other key components, especially the anti-theft system. Our VIN programming handles the most critical part of this process. However, the final stepโthe security relearnโmust be done on the vehicle itself. This is a standard procedure for any professional technician with GM-compatible scan tools and ensures that only your key can start your engine. By purchasing our Programmed 2017 Corvette ECM 12678815, you are getting a part that is 95% of the way there, making the final installation steps straightforward for a qualified installer.
Frequently Asked Questions
What exactly is a VIN-programmed ECM?
It means we take a new or fully tested ECM and load it with the specific factory software and calibration files that match your vehicle’s Vehicle Identification Number (VIN). This ensures the computer knows everything about your car, from its engine size and transmission type to its specific emissions equipment and electronic options.
Do I need to do anything after I install it?
Yes. While we program the core software, you or your mechanic will need to perform any necessary vehicle-specific relearn procedures. The most common is the vehicle anti-theft system (VATS/Pass-Key) relearn, which may be required for the vehicle to start. Other procedures, like a crankshaft position variation relearn, may also be necessary. This is a standard part of any professional ECM replacement.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is unique to your car.
