Restore Your Corvette’s Legendary Performance
The Engine Control Module (ECM) is the electronic brain of your 2014-2016 C7 Corvette, orchestrating everything from fuel injection and ignition timing to transmission shifts and emissions control. When it begins to fail, the symptoms can be frustrating and difficult to diagnose, ranging from a simple check engine light to a car that won’t start at all. This replacement Engine Control Module, part number 12673195, is the definitive solution to restore your vehicle’s factory performance, drivability, and reliability.
Unlike a generic part from a local store, this module is a direct-fit component that arrives at your door fully programmed to your Corvette’s specific Vehicle Identification Number (VIN). We handle the complex flashing process for you, loading the latest GM-authorized software and calibrations before it ships. This means no expensive trips to the dealership for programming, no special tools required, and a much simpler installation process. Simply provide your VIN after purchase, and we’ll ensure the module is perfectly matched to your car’s exact specifications and options.
From the Diagnostic Bay
We had a 2015 Corvette Stingray come in with a complaint that was driving the owner crazy. The car would run perfectly for days, then suddenly go into a reduced power mode with a flurry of warning lights. Other times, it would have a long crank before starting. We checked everything—sensors, wiring, fuel pressure—and it all looked good. The intermittent nature of the problem pointed towards an electronic issue. After scoping the network and running advanced diagnostics, we isolated the fault to the internal processor of the original ECM. It was failing under certain temperature conditions. We installed one of our VIN-programmed modules, performed the necessary security relearn procedure, and the car was back to its ferocious self. The owner was thrilled to have his car back, running reliably without the constant worry of an unexpected breakdown.
Diagnosing Your 2014-2016 Corvette ECM
A failing ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the issues below, a faulty engine computer could be the root cause. This module is the correct solution for restoring proper function and clearing persistent, module-related diagnostic trouble codes (DTCs).
Common Symptoms of a Failing Corvette ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately.
- ✔ Vehicle refuses to start or has intermittent no-start conditions.
- ✔ Noticeable decrease in fuel economy.
- ✔ Rough or unstable engine idle.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Reduced engine power or sluggish performance.
- ✔ Automatic transmission shifting erratically or harshly.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Various unrelated warning lights appearing on the instrument cluster.

Frequently Asked Questions
Do I need to send my old ECM to you?
No, there is no core charge or need to send your original module to us. This is an outright purchase. We program a replacement module and ship it to you.
Is this part difficult to install?
The physical installation is straightforward for someone with moderate mechanical skill. The ECM is typically located in the passenger-side cowl area under the dash. After installation, you will need to perform a security relearn procedure (also known as a key relearn or anti-theft relearn), which can often be done without special tools. Instructions for this procedure are widely available online or in service manuals.
What happens if I don’t provide my VIN?
Providing your VIN is mandatory for this part. We cannot program or ship the module without your vehicle’s specific 17-digit VIN. The programming is what makes this module work with your car’s systems. Please be ready to send us your VIN through messaging after you complete your purchase.
Will this ECM fix my car’s problem?
This module will correct any issues directly caused by a failing ECM. While the symptoms listed are common for ECM failure, they can also be caused by other faulty components like sensors or wiring. It is always best to have a proper diagnosis performed by a qualified technician to confirm the ECM is the point of failure before ordering.
Is this compatible with other GM trucks and cars?
Yes, while this listing focuses on the Corvette, part number 12673195 and its alternates are used across many GM vehicles from this era, including the Silverado, Sierra, Camaro, CTS, Escalade, and more. The programming we perform is specific to the VIN you provide, ensuring it works correctly whether it’s for a truck, SUV, or sports car.
