Is Your Camaro Feeling Sluggish or Unreliable?
A failing Engine Control Module (ECM) can turn your powerful 2012 Camaro into a source of constant frustration. If you’re dealing with a persistent check engine light, unexplained stalling, poor fuel economy, or a car that just won’t start, the problem often lies with a faulty engine computer. Don’t let a bad module keep you from enjoying the performance you expect. This is the definitive solution to restore your vehicle’s brain and bring its performance back to factory specifications.

Frequently Asked Questions
Do I need to do anything after I install the ECM?
In most cases, this is a plug-and-drive solution. However, some vehicles may require a simple Security Relearn Procedure (also known as a key relearn or anti-theft relearn), which can typically be done without any special tools. We include instructions for this straightforward process.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot program and ship your module until we receive this information. You can find your VIN on your vehicle’s registration, insurance card, or on the driver’s side dashboard viewable through the windshield.
Is this a brand new part?
This is a quality-tested, OEM-grade component that has been meticulously inspected and prepared to meet or exceed original factory standards. It is programmed with the latest software and is fully guaranteed to perform correctly.
My original part number isn’t 12642665, will this still work?
Yes. This ECM is a direct, compatible replacement for all the part numbers listed in the description, including 12616889, 12630908, 12637106, 12650256, and 12651993. As long as your original part number is on our list, this unit will work perfectly once programmed to your VIN.
Will this fix my specific problem?
While this ECM is the solution for a wide range of electronic and performance issues, we always recommend proper vehicle diagnostics. If your mechanic has diagnosed a faulty ECM, this part is the correct solution. It resolves issues stemming from a failed engine computer, but will not fix separate mechanical or sensor-related problems.
