Restore Peak Performance to Your Vehicle’s Engine
The Engine Control Module (ECM), often called the engine computer, is the central command center for your vehicle’s engine. It meticulously manages critical functions like fuel injection, ignition timing, and emissions systems to ensure optimal power, efficiency, and reliability. When the ECM begins to fail in your 2012-2015 Camaro or other compatible GM vehicle, it can lead to a cascade of frustrating and potentially damaging issues, from poor performance and rough idling to a complete no-start condition. This replacement ECM, part number 12633264, is the definitive solution to restore your vehicle’s factory performance and drivability.
I once had a 2012 Camaro ZL1 come in with intermittent stalling and a host of random communication codes. The owner had already replaced the throttle body and MAF sensor with no luck. Before condemning the ECM, I always start with the basics. I spent 20 minutes cleaning the main engine-to-chassis ground strap and the battery terminals. To my surprise, the car ran perfectly afterward. A poor ground was causing voltage drops that made the ECM behave erratically. Always check your power and ground connections before assuming the module itself is bad—it can save you hundreds of dollars and a lot of headaches.
Is Your Vehicle Exhibiting These Symptoms?
A failing ECM can manifest in various ways, often mimicking other component failures. If you’re experiencing any of the following, your engine computer could be the culprit:
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Unexplained drops in fuel economy.
- ✔ Engine misfires, stumbling, or hesitation during acceleration.
- ✔ Rough or erratic idling.
- ✔ Intermittent stalling or difficulty starting the engine.
- ✔ Harsh or incorrect shifting from the automatic transmission.
- ✔ Complete failure to start, with no spark or fuel delivery.
The Plug-and-Play Solution: A Programmed 2012-2015 Camaro ECM
Replacing an ECM isn’t as simple as swapping out a battery. Modern vehicle security systems require the module to be programmed specifically to your car’s Vehicle Identification Number (VIN). Our service eliminates the need for an expensive trip to the dealership. When you purchase this module, we flash it with the latest GM-certified software updates using the VIN you provide. This ensures that the ECM is perfectly matched to your vehicle’s specific options and systems, making for a straightforward, plug-and-play installation. No additional programming or dealer visits are required. You receive a component that is ready to install right out of the box, restoring the precise control your engine needs.
Simple VIN Programming Process
Our process is designed for your convenience. After placing your order, simply provide us with your vehicle’s 17-digit VIN. Our technicians will handle the rest, professionally programming the module to your exact specifications before it ships. This critical step ensures seamless integration with your vehicle’s anti-theft system (Pass-Key, V.A.T.S.) and other onboard modules.

Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming is the process of loading your vehicle’s specific software and security information onto the ECM. It’s essential for the module to communicate correctly with your car’s other systems, including the ignition, transmission, and anti-theft system. Without it, the vehicle will not start or run properly.
Do I need to do anything after installing this ECM?
In most cases, this is a plug-and-play installation. However, some vehicles may require a security relearn procedure, which is a simple process that can be done without special tools. Instructions are readily available online or in your vehicle’s service manual. No dealer visit is required.
Where is the ECM located on a 2012-2015 Camaro?
On the 2012-2015 Camaro, the ECM is typically located in the engine bay, on the driver’s side, near the fender or firewall. It’s a silver metal box with several large electrical connectors. Always disconnect the battery before attempting to remove or install the module.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. You can typically find your VIN on your vehicle’s dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your insurance and registration documents.
Is this a new or used part?
This is a high-quality, tested, and verified used component. Each unit is inspected to ensure it meets strict performance standards before being programmed with the latest software for your vehicle. This provides a reliable and cost-effective alternative to a new dealer part.
