This looks interesting:

And I wonder how they are switching the maps? It sounds like it re-flashes the map each time? I thought that someone could re-purpose existing alternate maps that the ECU already has? Or did they decompile, and put in their own maps, and switches.
Sounds like what the Mitsubishi guy's have been doing for a long time now!
