Hello all. I am new to EFI live and I want to learn to tune. I understand the basics just never owned a tool to tune. I bought a Durmax truck and part of the deal included EFI live. Looks like I have version 7.5 with flash scan V2. I have it fully installed on my lap top. There are several tunes in the files along with about 5-6 cars/trucks.

Do I need to do anything as far as purchase more VIN's etc in order to use this for my cars? Anything else I should know when buying/using a previously owned software? Thanks
