Just had the GS up on the dyno yesterday. Interestingly the AFR was consistently between 13.5- 14:1 at cruising speeds (40-80 mph). As a matter of fact, mostly between 13.5- 13.7. Only down low in the RPM (>3000) range did it exceed 14.5:1 . The peak probably being when the throttle opened abruptly.
I have a full system waiting to go on and will be returning to retest. According to BMW, the EFI will not take any time to adjust, but I will ride through at least one tank first.
