Restore Peak Performance to Your Vehicle’s Heart
The Engine Control Module (ECM), often called the engine computer, is the electronic brain of your vehicle. It is responsible for managing a complex web of sensors and systems to ensure your engine runs with optimal power, efficiency, and minimal emissions. When the ECM begins to fail in your 2014-2016 Corvette, or other compatible GM vehicle, it can lead to a cascade of frustrating and potentially damaging issues. This replacement Engine Control Module, part number 12669318, is the definitive solution to restore your vehicle’s factory performance and reliability.
This isn’t just a generic part off the shelf. We provide a crucial service by programming this module specifically to your vehicle’s Vehicle Identification Number (VIN) before it ships. This process loads the latest, most stable software updates directly from GM, ensuring that the module communicates flawlessly with your vehicle’s specific configuration, options, and security systems. This VIN-specific programming eliminates the need for an expensive trip to the dealership for software flashing, saving you time and money.
Is Your 2014-2016 Corvette Engine Control Module Failing?
A faulty ECM can manifest in numerous ways, from subtle performance dips to a complete no-start condition. If you’re experiencing any of the following, a failing engine computer could be the culprit. Timely replacement is key to preventing further complications with other vehicle systems.
Common Symptoms of a Failing Corvette ECM
- ✔ Check Engine Light: The most common indicator, often with codes related to module communication, sensor circuits, or processor faults.
- ✔ Engine Stalling or Misfiring: The ECM may fail to correctly time spark or fuel injection, leading to rough running, stalling, or hesitation.
- ✔ No-Start Condition: If the ECM cannot power up or communicate with the ignition and fuel systems, the engine will not start.
- ✔ Poor Fuel Economy: Incorrect air/fuel mixture calculations can cause a sudden and significant drop in MPG.
- ✔ Shifting Problems (Automatic Transmissions): The ECM works with the Transmission Control Module (TCM), and a fault can cause harsh or erratic shifting.
- ✔ Intermittent Electrical Issues: Seemingly unrelated problems with cooling fans, gauges, or other systems can sometimes be traced back to a faulty ECM.

This is a simple procedure that can often be performed without special tools and instructions are readily available online for your specific model.
Frequently Asked Questions
What does the VIN programming service include?
Our programming service involves loading your vehicle’s specific 17-digit VIN into the module. This process configures the ECM with the correct software and calibrations for your engine, transmission, and factory options, ensuring it functions exactly as the original part did.
Is this part difficult to install?
The physical installation is typically straightforward for someone with moderate mechanical skill. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. The location varies by vehicle (e.g., RH cowl for Corvette, LH front engine compartment for Silverado). The most critical part is ensuring the connectors are seated properly on the new unit.
Will I need to do anything else after installing this ECM?
In many cases, you may need to perform a security relearn procedure, also known as a VATS relearn. This syncs the new ECM to your vehicle’s immobilizer system. It’s a simple process that usually involves turning the key on and off in a specific sequence. We recommend searching for the procedure for your specific year and model.
How do I know if this part number is correct for my vehicle?
The best way is to match the part number from your existing module to our compatible numbers list. Our extensive fitment list also details the specific models and options this part fits. If you are unsure, please contact us with your VIN before ordering.
What happens if I continue driving with a bad ECM?
Continuing to operate a vehicle with a failing ECM can lead to more severe problems. You may experience catalytic converter damage from an incorrect air/fuel mixture, poor engine performance leading to unsafe driving conditions, or eventually a complete no-start situation, leaving you stranded.
