Restore Peak Performance to Your Corvette
Is your 2009 Corvette suffering from mysterious electrical issues, a persistent check engine light, or poor engine performance? The Engine Control Module (ECM), the electronic brain of your vehicle, is often the culprit. A failing ECM can cause a cascade of problems that can be difficult to diagnose, leaving you frustrated and your high-performance machine sidelined. This genuine GM Engine Control Module, part number 12628911, is the definitive solution to restore your vehicle’s factory performance, drivability, and reliability.
Unlike a generic part from a local store, this ECM is delivered to you fully programmed and ready for installation. We take your vehicle’s unique Vehicle Identification Number (VIN) and flash the module with the latest, most up-to-date software directly from General Motors. This critical service ensures perfect compatibility with your Corvette’s specific systems, eliminating the need for an expensive trip to the dealership for programming. It’s the most efficient way to get your car back to its optimal state.
Common Symptoms of a Failing 2009 Corvette ECM
If you’re experiencing any of the following issues, a faulty engine computer may be to blame. A failing ECM can mimic other problems, but if you notice several of these symptoms, it’s a strong indicator that the central computer needs attention.
- âś” Persistent Check Engine Light (CEL) with various or no specific codes.
- âś” Unexplained engine stalling or hesitation during acceleration.
- âś” Noticeable decrease in fuel economy.
- âś” Engine misfires or rough idling.
- âś” Difficulty starting the engine or a complete no-start condition.
- âś” Automatic transmission shifting erratically or harshly.
- âś” Loss of communication with diagnostic scan tools.
- âś” Intermittent issues with other electronic modules in the vehicle.
From the Diagnostic Bay
We once had a 2009 Corvette ZR1 in the shop with a frustrating, intermittent misfire that no one could solve. The owner had replaced plugs, wires, and even coil packs, but the problem persisted, only appearing after the engine was fully warmed up. Diagnostic tools showed no consistent codes. After exhausting all mechanical possibilities, we focused on the ECM. We swapped in a test unit, and the problem vanished instantly. The original ECM had an internal fault on a driver circuit that only manifested under specific temperature conditions. It’s a classic example of how a failing computer can send you chasing ghosts, and why replacing it with a correctly programmed unit is the only real fix.
Plug-and-Play Solution with Professional Programming
The biggest hurdle in replacing a modern vehicle’s computer is the programming. This 2009 Corvette ECM eliminates that obstacle. Our process is simple and effective:
- Place Your Order: Add this item to your cart and proceed to checkout.
- Provide Your VIN: During checkout, you will be prompted to enter your vehicle’s 17-digit VIN.
- We Handle the Rest: Our technicians use your VIN to access the official GM database and load the correct software and calibrations onto the module.
- Install and Drive: The module arrives at your door, ready to be installed. In most cases, it’s a direct swap.
In some instances, a Crankshaft Variation Relearn (also known as a CASE relearn) may be required after installation to ensure the computer accurately reads the crankshaft position sensor. This procedure can often be performed without special tools and is necessary for optimal engine timing and misfire detection.

Frequently Asked Questions
Do I need to get this 2009 Corvette ECM programmed by a dealer?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready for installation with the latest GM software for your specific car.
What information do you need from me?
We only need your 17-digit Vehicle Identification Number (VIN). This allows us to flash the ECM with the exact software and calibrations your vehicle requires from the factory.
Is this a simple plug-and-play installation?
Yes, for the most part. Once you swap the hardware, the vehicle will start and run. However, for perfect operation, some vehicles may require a security relearn procedure or a Crankshaft Variation (CASE) relearn, which synchronizes the ECM with your engine’s sensors. These procedures are often straightforward.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, if the light is on due to other failing sensors or mechanical problems, those issues will still need to be addressed separately.
How do I know if this part number is correct for my vehicle?
This module (12628911) is interchangeable with several other GM service numbers, including 12636659, 12639300, and 12625453. As long as your vehicle is on the compatibility list and you provide your VIN, we will ensure it is programmed correctly to function as a direct replacement.
