It works through your laptop...I am thinking of getting it and if anyone around me wants to play with there car can come and hook up and make all the changes they want, for a small fee......I run a small custom shop and i may do it through that, do like 40 bucks a tune just to cover my cost a lil bit, not sure it is 500.00 to buy so it may be a while
