I'll second what africajon said, Adrian did mine at the end of a trial, took 10 minutes.  Contact him ahead of time so he knows to bring the laptop and battery.  Bear Valley is in a couple of weeks and will be a blast, plan to ride it if you can.

 No- when you read the firmware version it shows it has a dual map.  It doesn't not show details about how the map actually works (rich/lean/advance etc).

Software is readily available, just the cables are not currently abundant. (Especially reasonably priced ones).

Both ECUs use the same cable and software, just a different end for the 4 pin vrs 6 pin.
