Restore Peak Performance to Your C7 Corvette
Is your 2014-2016 Corvette suffering from perplexing engine issues, a persistent Check Engine Light, or inconsistent performance? The Engine Control Module (ECM), the electronic brain of your vehicle, is often the culprit. This vital component orchestrates everything from fuel injection and spark timing to transmission shifts and emissions control. When it fails, the driving experience you expect from your high-performance machine can be severely compromised. This listing is for a genuine GM Engine Control Module, part number 12672963, that arrives at your door pre-programmed with the latest GM software specific to your vehicle’s VIN.
From the Diagnostic Bay
We had a 2015 Corvette in the shop that was driving the owner crazy. It had a random, intermittent misfire that wouldn’t set a consistent code. The owner had already replaced plugs, wires, and a coil pack with no success. After hours of diagnostics, we traced the issue back to a failing driver circuit within the original ECM. A simple swap with one of our pre-programmed modules had the car running perfectly in under an hour. It’s a powerful reminder that sometimes the root cause lies with the controller, not just the components it manages.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough or erratic idling.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Issues with automatic transmission shifting.
The Simple, Reliable Solution: A VIN-Programmed 2014-2016 Corvette ECM
Don’t let a faulty computer keep your Corvette parked. Our service eliminates the most significant hurdles of ECM replacement. Dealerships often require you to have the vehicle towed in for expensive diagnostic and programming sessions. We simplify the process entirely. By providing us with your vehicle’s VIN during checkout, we can flash this module with the precise factory software and calibration files for your Corvette’s specific configuration. This ensures all systems communicate correctly and your engine operates exactly as the engineers intended. This is not a generic, one-size-fits-all solution; it’s a tailored fix for your specific car.
This module is a direct replacement for multiple part numbers, ensuring wide compatibility. It is compatible with the following part numbers: 12692067, 12676230, 12656993, 12662034, 12672537, 12673195, 12663391, 12672963, 12669318. While this ECM fits a variety of GM trucks and cars, this listing is specifically for owners seeking a solution for their 2014-2016 Corvette.
Installation Process
After receiving your pre-programmed module, the physical installation is straightforward. On the C7 Corvette, the ECM is located on the right-hand side, under the cowl panel. Simply disconnect the battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. After reconnecting the battery, you may need to perform a security relearn procedure, which can often be done without special tools. This ensures the new ECM communicates with your vehicle’s anti-theft system. We are here to assist if you have questions about this final step.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to access the exact GM factory software, calibrations, and updates for your Corvette’s specific engine, transmission, and options. Programming the ECM with your VIN is essential for proper function and avoids compatibility issues.
Is this part difficult to install?
The physical replacement is relatively simple for someone with basic mechanical skills. It involves disconnecting the battery, removing the old module, and installing the new one. The most critical step after installation is the security relearn procedure, which pairs the new ECM to your car’s security system.
Will this fix my car’s specific problem?
This ECM will resolve issues directly caused by a faulty engine computer. While the symptoms listed are common indicators of ECM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the root cause before ordering.
What if my original part number is not on your list?
Please contact us with your vehicle’s VIN and original part number. GM often supersedes part numbers, and we can verify if this module is the correct, updated replacement for your specific application.
Is any additional programming required after installation?
No dealership programming is needed. We handle the main programming before shipment. You will likely need to perform a security relearn (also known as a Passlock or anti-theft relearn) and possibly a Crankshaft Position Sensor (CASE) relearn, which can often be done without a high-end scan tool.
