Is Your 3.6L V6 Camaro Running Rough? The ECM Might Be the Culprit.
The Engine Control Module (ECM), often called the engine computer, is the electronic brain of your 2010-2011 Chevrolet Camaro. It’s responsible for managing everything from fuel injection and ignition timing to transmission shift points and emissions controls. When it starts to fail, it can cause a cascade of confusing and frustrating problems that can be difficult to diagnose. If you’re experiencing erratic engine behavior, a persistent check engine light, or a no-start condition, a faulty ECM is a likely cause.
This isn’t just a replacement part; it’s a complete solution. We provide a genuine GM Engine Control Module, part number 12635019, that is professionally programmed with the latest GM software updates specifically for your vehicle. By providing your Vehicle Identification Number (VIN) during checkout, you ensure that the module you receive is precisely calibrated for your Camaro’s specific options and systems, restoring its original performance and reliability.
From the Diagnostic Bay
We had a 2011 Camaro 3.6L come into the shop with a classic complaint: intermittent stalling at red lights and a P0300 random misfire code that just wouldn’t go away. The owner had already spent a small fortune replacing all the spark plugs, ignition coils, and even the fuel injectors. The problem persisted. After hooking up our diagnostic scanner and monitoring live data, we noticed the injector pulse width commands from the ECM were erratic on multiple cylinders. Instead of firing precisely, they were getting inconsistent signals. We swapped in a known-good, programmed ECM, and the car ran perfectly. It was a textbook case of a failing driver circuit inside the original module. This highlights why it’s crucial to consider the ECM when you’ve exhausted the more common culprits.
Common Symptoms of a Failing 2010-2011 Camaro ECM
- ✔ Persistent Check Engine Light (CEL) with various trouble codes.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ Noticeable decrease in fuel economy.
- ✔ Engine misfires or rough idling.
- ✔ Difficulty starting the engine or a complete no-start condition.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Loss of power and poor overall engine performance.
Why Our Programmed 2010-2011 Camaro ECM is the Right Choice

Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) is essential for programming the ECM correctly. It allows us to load the specific software and calibrations for your car’s engine, transmission, and factory options. This ensures seamless integration and proper function without needing a trip to the dealership.
What is the process for Camaro and Lacrosse owners?
For these specific models, the factory anti-theft (immobilizer) system is deeply integrated into the ECM. To make the replacement unit plug-and-play, we require you to send us your original ECM. We will professionally extract the immobilizer data and program it into the new module. We will provide shipping instructions after your purchase.
Is this ECM difficult to install?
The physical installation is straightforward for someone with basic mechanical skills. The ECM is typically located in the engine bay and is held in by a few bolts and electrical connectors. The most important step is to disconnect the battery before starting. Since we handle all the programming, no special tools are required for software setup after installation.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then this part will resolve the issue. However, the check engine light can be triggered by many different components. It is always best to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
Is this a new or used part?
This is a high-quality, inspected, and tested OEM component that has been professionally programmed with the latest software for your vehicle. It is guaranteed to restore your vehicle’s functionality to factory specifications.
