Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM) is your vehicle’s main computer. It controls and monitors the engine’s critical functions, including fuel mixture, ignition timing, and emissions systems, to ensure optimal performance, fuel economy, and reliability.

After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will then program the module specifically for your car before shipping it to you. This ensures it’s ready to install right out of the box.
Is any additional programming required after installation?
In most cases, no. Because the unit is pre-flashed to your VIN, it is typically a plug-and-play installation. However, some vehicles may require a simple security or CASE relearn procedure, which can often be done with a capable scan tool.
How can I be sure this fits my vehicle?
This ECM fits a 2008 Buick Lucerne and many other GM models as listed in the fitment data. The key is matching the service number. Providing your VIN during checkout allows us to confirm perfect compatibility and program the correct software for your exact vehicle configuration.
