[QUOTE="harvboi05, post: 11429556, member: 88199"] i find it easier to explain afr's with closed loop and open loop. closed loop (using the o2s) your ecm will be trying to hit your target AFR which is usually 14.7. open loop (WOT not using the o2s) the ecm will be running off the maf, and the AFR will be whatever you calibrate it to. the lower the number the richer the AFR, the higher the number the leaner the AFR. its not really cut and dry lean rich, it can be more and less too.
