How are vehicles licensed?
Licenses consist of three pieces of information. They tie in VIN, Serial Number of the module and OS. If you change any of this information you will break the license and have to license the new combination of information you created. You will need to hold a license for the file you are writing as well as the vehicle you are writing to.
Why would I need to relicense my vehicle?
If you change the VIN, the OS on the controller or swap the controller, you will have to license the new combination of information that is created. If you brought your vehicle to a dealer and had it flashed to stock there is a chance they would update to a different operating system. Additionally if you are using a handheld programmer to switch back & forth between tunes this could also change the operating system id.
What about licensing files from the repository?
Licensing files from the repository is ill-advised. Those files were uploaded by other customers and should only be used as reference, you should NEVER license them or load them into your ecm. Doing so will use multiple credits (that cannot be refunded nor can the licenses be reversed) and in many instances customers have fried their ecm's in doing so by flashing incompatible files to their ecm. We also reference this in the licensing screen in our software.
