I think that somewhere around 15 or 15.2 AFR is best efficiency. 14.7 is good for emissions. Wider throttle openings do help with efficiency because the wider throttle opening cuts pumping losses - less vac sucking against a closed throttle plate.
You are correct about driving technique, though. I went from 17mpg to 22pmg in my truck by carefully adjusting the loose nut between the seat and steering wheel. :) -Chuck Russ wrote: > Makes sense to me (fuel map).
