Restore Peak Performance to Your High-Powered GM Vehicle
As a technician with over two decades of experience under the hood, I’ve seen firsthand the frustration a failing Engine Control Module (ECM) can cause. Your 2010-2013 Corvette isn’t just a car; it’s a high-performance machine, and its brain—the ECM—is critical. When it starts to falter, you can experience everything from a nerve-wracking Check Engine Light to intermittent stalling or a complete no-start condition. This isn’t just an inconvenience; it robs you of the driving experience you love.
This isn’t just a replacement part. This is a complete solution. We take a genuine GM ECM (service part number 12633264, interchangeable with 12678513) and professionally program it to your vehicle’s specific Vehicle Identification Number (VIN). This means it arrives at your door loaded with the latest GM software updates, ready for installation. You get to bypass the expensive trip to the dealership for programming, saving you significant time and money.
From the Diagnostic Bay: The Intermittent Stall Case
I remember a 2011 Corvette Z06 that came into my shop with a problem that drove the owner crazy. It would run perfectly for days, then suddenly stall at a red light. No consistent codes, just a random, unpredictable shutdown. After hours of checking fuel pressure and sensors, we hooked up a scope to the ECM’s main processor. We discovered intermittent voltage drops internally within the module itself, a classic sign of heat-related failure on the circuit board. Swapping in a pre-programmed 2010-2013 Corvette ECM like this one solved the issue immediately. The customer was back on the road with confidence, having avoided a much more expensive and lengthy dealership diagnosis.
Common Signs of a Failing Engine Computer
If your vehicle is the heart of your driving passion, the ECM is its brain. When it’s not functioning correctly, your car will let you know. Watch out for these common symptoms:
- ✔ Check Engine Light is illuminated with communication or internal processor codes (e.g., P0601, P0606, U0100).
- ✔ The engine cranks but refuses to start.
- ✔ Unexplained stalling or rough idling, especially after the engine warms up.
- ✔ A noticeable decrease in fuel economy and engine performance.
- ✔ Problems with automatic transmission shifting.
- ✔ Apparent failure of fuel injectors or ignition coils with no issues found in the components themselves.
A Straightforward Guide to Swapping Your ECM
This installation is manageable for a DIY enthusiast with basic tools. The key is our VIN-programming service, which handles the most complex step for you. A simple security relearn procedure is typically required after installation.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes to allow all capacitors to discharge.
- Locate the Module: On the 2010-2013 Corvette, the ECM is typically found in the engine compartment on the right-hand (passenger) side. Consult your service manual for the exact location on other compatible vehicles.
- Disconnect and Remove: Carefully unplug the electrical connectors. Most have a locking tab that needs to be released. Once disconnected, unbolt the old ECM from its mounting bracket.
- Install the New ECM: Mount the new, pre-programmed module in place and securely fasten it. Reconnect all electrical connectors, ensuring they click firmly into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Security Relearn: Most GM vehicles require a security relearn procedure to sync the new ECM with your vehicle’s anti-theft system. This usually involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. Your vehicle should then start.

Frequently Asked Questions
Frequently Asked Questions
Do I need to program this module?
No. This ECM comes fully programmed to your car’s VIN with the latest GM software updates before we ship it. You just need to perform a simple security relearn procedure after installation.
What is the security relearn procedure?
It’s a process that allows your vehicle’s anti-theft system to recognize the new ECM. It typically involves a sequence of key turns and waiting periods. We include general instructions, but the exact steps can vary slightly by model.
Where is the ECM located on my 2011 Corvette?
On the 2010-2013 Corvette models, the Engine Control Module is located in the engine bay, on the passenger side, near the firewall.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM (like codes P0601 or P0606), then yes, this part is the correct fix. It’s crucial to properly diagnose the issue first to ensure the ECM is the root cause.
What information do you need from me?
After you place your order, we will need the 17-digit Vehicle Identification Number (VIN) from your vehicle to program the module correctly.
