From what I have read, they are moving the EWG control along on the M550i platform, so that may be here for us soon.

BM3 says they are interested, but have no ETA. I wonder what's the state of the other flash tunes?
Yes, RaceChip is on TMAP.

By the time you are plugging more things than TMAP, might as well go to flash tune. Much2 better than 8 bit processor controlling multiple high speed sensors reading.
Also, how do you know that they use the OBD2 / CANBUS reading for timing or fuel control?
AFAIK, it is only for reading, not overriding or writing over the CANBUS signal.
