Restore Your C6 Corvette’s Brainpower and Performance
Is your 2006 or 2007 Corvette suffering from baffling electrical issues, a persistent Check Engine Light, or unpredictable performance? The Engine Control Module (ECM), the central computer of your vehicle, is often the root cause. A failing ECM can lead to a cascade of problems, from poor fuel economy and rough idling to a frustrating no-start condition. This replacement Engine Control Module, part number 12589297, is the definitive solution to restore your Corvette’s factory performance and reliability.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and high cost out of the equation by programming the module specifically to your vehicle’s Vehicle Identification Number (VIN) before it ships. This crucial step ensures that the ECM communicates perfectly with your Corvette’s other systems, including the transmission, anti-lock brakes, and security system, eliminating the need for an expensive trip to the dealership for programming.
From the Diagnostic Bay
We had a 2007 Corvette come into the shop with a complaint that was driving the owner crazy. It would randomly stall at stoplights, the gauges would flicker intermittently, and it threw a host of communication error codes (U-codes) that seemed to have no connection. We checked grounds, wiring harnesses, and sensors for hours. Finally, we focused on the ECM. On the surface, it seemed fine, but under load and heat, the internal processors were failing. We swapped in a VIN-programmed ECM just like this one, and it was like a new car. All the ghost-like issues vanished instantly. It’s a powerful reminder that the ECM is the true heart of the vehicle’s electronic system.
Common Symptoms of a Failing Corvette ECM

- ✔ Harsh or erratic automatic transmission shifting
- ✔ Intermittent stalling or difficulty starting the engine
- ✔ Complete no-start condition where the engine cranks but won’t fire
- ✔ Loss of communication with diagnostic scan tools
- ✔ Inaccurate gauge readings or warning lights

Frequently Asked Questions
What does an ECM do on my Corvette?
The Engine Control Module (ECM) is your Corvette’s main computer. It controls critical engine functions like fuel injection timing, spark timing, variable valve timing, and emissions systems. It constantly analyzes data from sensors throughout the vehicle to ensure the engine is running at peak efficiency and performance.
Is programming really included?
Yes, absolutely. The price includes programming the module to your specific vehicle using the VIN you provide. This ensures the unit is ready for installation right out of the box, saving you a costly trip to the dealer.
Where is the ECM located on my 2006-2007 Corvette?
On the C6 Corvette models from 2006-2007, the ECM is located in the engine bay, on the right-hand (passenger) side, near the firewall and tucked beside the fender.
Will I need to do anything after I install it?
In many cases, the vehicle will start and run immediately. However, you may need to perform a security relearn procedure (often called a Passlock or VATS relearn) which allows the new ECM to communicate with your vehicle’s anti-theft system. This procedure can typically be done without special tools and instructions are widely available online.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the module until we have this information, as the programming is essential for the part to function.
