As I understand it, the AUTOCAL is mostly up to who you buy it from as to what it can do. It still has to be licensed under a V2 in order for it to work as it was designed for tuners with EFILIVE already to keep from having customers send there ECM's back and forth for tune changes. Also it is licensed to one vehicle and one vehicle only as I understand it as well. Once it is matched with a module, that is the only one it can be used with(I may have misunderstood this, but its how it was explained to me).
