Your Vehicle Identification Number (VIN) is essential because it contains specific information about your car’s engine, transmission, and factory-installed options. We use the VIN to load the exact GM-certified software your vehicle requires, ensuring perfect communication between all onboard computers and a seamless, error-free installation.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is very manageable. The ECM on the 2008-2009 LaCrosse is typically located in the lower air cleaner housing.

What happens after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s VIN. Once we receive it, our technicians will program the module, a process that typically takes 1-2 business days. We will then ship the ready-to-install part directly to you.
Will I need to perform a security relearn procedure?
In many cases, a security or anti-theft relearn procedure may be necessary after installation for the vehicle to start. This is a simple process that typically involves turning the key on and off in a specific sequence. We include instructions for this procedure with your order.
My old computer has a different service number on it. Will this work?
