Frequently Asked Questions
What exactly does the PCM do?
The Powertrain Control Module, or PCM, is the central computer for your vehicle. It controls all aspects of the engine and transmission, including fuel injection, ignition timing, spark, and transmission shift points, to ensure optimal performance, efficiency, and emissions.
Is any additional programming needed after I install it?
No. This module is shipped fully programmed to your vehicle’s VIN. In most cases, it is a direct plug-and-play installation. Some vehicles may require a security relearn procedure, which is a simple process that can be done without any special tools. Instructions are readily available online for your specific model.
How do I provide my VIN after purchase?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module until we receive this information.
