I have a few questions when tuning AFR.

First and foremost, the AFR when I log does not match the open loop fueling table. For example, I am supposed to be getting 11.8 or so at 1.4 load, 6k rpm, but instead at wot I am basically always getting a commanded AFR of 11.25:1. What is causing this? Thanks

(Edit: For future thread readers, this becomes kind of confusing... I wasn't looking at commanded AFR... I was actually looking at the measured AFR in logs and thinking it was commanded. Read further to see that we eventually figure this out, then everything becomes pretty straightforward. OFT has both a commanded AFR output and AFR output in logs. "AFR" means "measured AFR" in logs.)
