This means that when you are cruising around (TPS <30%) you are on the SAFC-II's lo throttle map. This map is set to maximize fuel efficiency by keeping the AFR around 14.7:1.

When you go WOT (or anything at a TPS >80%) the SAFC-II switches to the hi-thorttle map. The hi-throttle map was the one that was altered on the dyno. This map is designed for maximum power at a much richer AFR.....in my case 11.3:1.
Ok i was wondering this also so lo-throttle setting is <30%, and hi-throttle setting is 80%>? so whats in between how do you adjust in between 30 and 80? i have wondered this?

Next no a narrow band with a good narow band sensor isnt going to help more or less give anywhere NEAR close to what accual AF ratio is. Wideband is the ONLY way. unless you get a narrow band conversion kit, but then its not worth it because widebands alsmost cheaper.
