Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential because it allows us to load the exact, vehicle-specific software and calibrations from GM. This ensures the ECM communicates perfectly with your engine, transmission, and other onboard systems, making the installation a simple plug-and-drive process.
Is this difficult to install?
For someone with moderate mechanical experience, the physical installation is typically straightforward. It involves disconnecting the battery, locating and unplugging the old ECM, and installing the new one. Since our unit comes pre-programmed, you avoid the most difficult part of the processโthe software flashing. However, we always recommend professional installation if you are not comfortable working on your vehicle.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty ECM, this part is the correct solution. It’s crucial to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
What is the difference between an ECM, ECU, and PCM?
The terms are often used interchangeably. ECM (Engine Control Module) and ECU (Engine Control Unit) typically refer to the same part. PCM (Powertrain Control Module) is a module that controls both the engine and the transmission. For your vehicle, this part serves as the primary engine computer.
