Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before we ship. Just provide your VIN when you order, and the module will arrive ready for installation. It’s a true plug-and-play solution.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your car. It allows us to load the exact software and calibrations your specific vehicle needs for proper engine, transmission, and emissions control.

Is this a simple DIY job?
For someone with basic mechanical skills, yes. It typically involves disconnecting the battery, unplugging the old module’s electrical connectors, unbolting it, and then reversing the process. We always recommend consulting a repair manual for your specific vehicle’s procedure.
