Restore Peak Performance to Your C6 Corvette
Is your 2008 or 2009 Corvette suffering from mysterious electrical gremlins, poor performance, or a persistent Check Engine Light? The Engine Control Module (ECM), the central computer of your vehicle, is often the culprit. This vital component manages everything from fuel injection and ignition timing to transmission shifts and emissions systems. When it begins to fail, it can cause a cascade of frustrating and difficult-to-diagnose issues. This replacement Engine Control Module, part number 12612384, is the definitive solution to restore your vehicle’s factory performance and reliability.
This isn’t just a generic, off-the-shelf part. We provide a fully programmed, plug-and-play solution tailored specifically to your vehicle. Upon purchase, simply provide us with your Vehicle Identification Number (VIN), and our technicians will flash the module with the latest, most stable GM-certified software for your Corvette’s exact configuration. This critical step ensures seamless integration, eliminating the need for an expensive trip to the dealership for programming. Your new ECM will arrive ready for installation, getting you back on the road faster.
From the Diagnostic Bay
We had a 2008 Corvette Z06 come into the shop with a complaint that was driving the owner crazy. The car would randomly stumble at idle, the cooling fans would run constantly, and occasionally it would refuse to start altogether. There were no consistent trouble codes, just a slew of intermittent communication errors. We checked grounds, wiring harnesses, and sensors for days. Finally, on a hunch, we monitored the ECM’s internal temperature data and saw erratic spikes. We swapped in a known-good, programmed module, and every single issue vanished instantly. The original ECM was failing internally, causing system-wide chaos. It’s a perfect example of how a failing computer can mimic a dozen other problems.
Is Your Corvette ECM Failing?
A faulty 2008-2009 Corvette ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your engine’s computer may be at fault:
- ✔ Check Engine Light: An illuminated CEL with communication-related codes (like U0100) or multiple random misfire codes can point to the ECM.
- ✔ No-Start or Hard-Start Condition: The engine cranks but refuses to start, or takes an excessively long time to fire up, especially when warm.
- ✔ Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, and rough idling are classic symptoms.
- ✔ Reduced Fuel Economy: If the ECM isn’t managing the engine’s fuel and air mixture correctly, your gas mileage can drop significantly.
- ✔ Erratic Transmission Behavior: The ECM works with the Transmission Control Module (TCM) to manage shifting. A failing ECM can cause harsh shifts, delayed engagement, or getting stuck in a gear.
- ✔ Intermittent Stalling: The engine may stall for no apparent reason, either at idle or while driving.
- ✔ Cooling Fans Running Constantly: The ECM controls the cooling fan relays. If it fails, it may default to running the fans at all times as a failsafe.

Frequently Asked Questions
Do I need to do any programming after I receive this ECM?
No. We program the module with the latest GM software using the VIN you provide before we ship it. It will arrive ready to install. In some cases, a security relearn or crankshaft position sensor relearn may be necessary, which can be done with a capable scan tool or a simple key-cycle procedure.
Where do I provide my VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship the part until we receive this information, as the programming is essential for the part to function in your vehicle.
Is this a new or used part?
This is a high-quality, inspected, and tested used OEM part. Each module is verified to be fully functional before being programmed with your vehicle’s specific software.
Will this fix my car’s problem?
This module will correct issues directly caused by a faulty ECM. While the symptoms listed are common for ECM failure, we always recommend a proper diagnosis by a qualified mechanic to confirm the ECM is the root cause before ordering.
What is the difference between an ECM and a PCM?
The terms are often used interchangeably. ECM stands for Engine Control Module, while PCM stands for Powertrain Control Module. In most modern vehicles like your Corvette, the module controls both the engine and the transmission, making ‘PCM’ the more technically accurate term, but ‘ECM’ is still widely used and understood.
