I'm sure someone can explain it better then I, but my understanding is that the software that access your ecu to put the tune in need to buy an access license for each ecu it accesses. Take it back to the same guy, and you shouldnt be charged an license fee each time, maybe just a fine tune fee. Ive had little done to mine since the initial stuff, had to send it back once and he made a few mods for free.
