AF-xied instructions recommends setting of 7 for BMW and their experience is "6-8 works best".

They also through out a caveat that "free flowing exhaust" might require leaner settings.

I started at 7 and while the bike ran well (no more cold start stalling) it killed my fuel economy. I went from 140 miles before the low fuel light came on to 100 miles.

I've reset to number five and the engine runs like it always has with a cold start stall or two and the fuel economy is closer to what I used to get pre-AF-xied.
