Is Your C6 Corvette Running Rough or Showing a Check Engine Light?
The Engine Control Module (ECM) is the brain of your 2010-2013 Corvette, orchestrating everything from fuel injection and spark timing to transmission shifts and emissions control. When it starts to fail, the symptoms can be frustrating and difficult to diagnose, ranging from poor fuel economy and hesitation to a car that won’t start at all. Don’t let a faulty computer sideline your high-performance machine. This is the direct, reliable solution to restore your Corvette’s peak performance and operational integrity.
The Smart Solution: Pre-Programmed for Your Exact Vehicle
Forget the hassle and expense of a dealership visit. We take the complexity out of the repair by programming this ECM specifically for your Corvette before it even leaves our facility. Simply provide us with your Vehicle Identification Number (VIN) during checkout, and our technicians will flash the module with the latest, most stable software updates directly from GM. This ensures perfect compatibility and function right out of the box.
A Technician’s Real-World Experience
“A customer’s 2011 Corvette Z06 came in last week with an intermittent, high-RPM misfire that was driving him crazy. He had already replaced the plugs, wires, and a coil pack with no success. After hooking up my scan tool and monitoring live data, I noticed the injector pulse width for cylinder 3 was erratic under load. A quick check of the wiring confirmed it was solid. The culprit? A failing injector driver inside the original ECM. It’s a classic failure I’ve seen dozens of times on these E38 and E67 computers. We installed one of our pre-programmed modules, performed the security relearn, and the car ran perfectly, pulling strong all the way to redline. It saved the customer from throwing more money at parts he didn’t need.”
Common Symptoms of a Failing 2010-2013 Corvette ECM:
- ✔ Persistent Check Engine Light (CEL) with various trouble codes
- ✔ Engine stalling, stumbling, or hesitating during acceleration
- ✔ Noticeable decrease in power and fuel efficiency
- ✔ Communication errors with scan tools or other modules
- ✔ Harsh or incorrect automatic transmission shifting
- ✔ Complete no-start or intermittent starting condition
Plug-and-Play Installation: No Dealer Visit Required
Installing your new ECM is a straightforward process that you can do in your own garage. While the final step requires a security relearn procedure (which can be done without special tools), the physical installation is simple.
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the ECM: On the 2010-2013 Corvette, the ECM is located in the right-hand (passenger side) of the engine compartment, near the firewall.
- Disconnect Connectors: Carefully release the locking tabs and unplug the wiring harness connectors from the old module. Inspect the connectors for any corrosion or damage and clean if necessary.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed ECM onto the bracket and securely plug in the wiring harnesses.
- Reconnect Battery: Re-attach the negative battery terminal.
- Perform Security Relearn: Complete the vehicle’s anti-theft security relearn procedure. This typically involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’, and repeating two more times. Your vehicle’s service manual will have the exact steps.
