ok based on this then it looks like the 15-17 AFR sitting at idle is ok and the AFR clearly drops toward 14 and lower as i step on the gas so im guessing that when i drive it should drop to the normal range.... it that right??
looking like 17 is right about at best fuel economy so i shouldnt worry about my engine leaning out as long as it doesnt go past 18 correct??? or did i get this completely wrong?

12.2 Safe best power at WOT <---- this is what you want
13.3 approximate lean best torque
14.6 Stoichiometric AFR (chemically Ideal) <--- this is what you want for Lowthrottle setting [cruise]
15.5 lean cruise
16.5 usual best economy
18.0 carburated burn limit
22+ ecc/EFI lean burn limit.
