[quote=Munit]Cool features but kind of useless if you can't switch maps. How can the vishnu and jb3 stuff have been doing map switching for years? Is it because their chips can do that and a flash cannot?[quote=Munit]

That's because the"chips" that Vishnu and BMS offer are not a real tune. They are signal modifiers that fool the DME, not tune it. It's a lot easier to do as an external device than actual reflash. If you want that, perhaps the procede is your cup of tea on the M3. In that regard, you would be the minority.
