Single vehicle licenses will work only with the specific vehicles VCM you have locked the license to.

Year/Model type licenses will work on an unlimited number of vehicles of that particular model and year.

Unlimited vehicle group licenses will allow you to tune all vehicles that fall under that vehicle group category.

You do not need to know which license method you prefer at the time of order but will be prompted by the software for your selection when you tune the vehicle for the first time. Here is what License Activation looks like.

Our product is designed to work for vehicles off of the show room floor with stock calibrations. If your vehicle is a hybrid or has a physically different PCM/VCM than it originally came with your vehicle might not be supported.
