well hopefully my maths right on this. cause ive always sucked at it LOL... but with the graph i have come up with. put my idle afrs inbetween 15.0-16.3. so if i pick the leanest point of 16.3 and i want a afr of 14.3 that would work out to 1.140%. so if i grab the majority of my idle cells and mulitply them by that i should be in the ballpark.. just sucks that my afrs arnt all the same like a flat 14.7 up to say 1050rpms.. that would be alot easier to work out the math instead of having to go frame by frame in the datalog to find out what my afrs are... like cruise and stuff my afrs are on point.. maybe fluctuating like .3 off target but during shifts and idle my afr goes lean cause of the graph.. so i was thinking of just multiplying the whole idle area 100kpa down to 0 and up to 1050rpm by the 1.140% and see what it does but something tells me that my cars gonna burn super rich from a cold start.. or richen up when warm and die and burn a set of plugs.. cause i remember when i did the build and my idle ves were up there in the 55-60s and it burnt out a set of plugs being so rich.. but i guess we will see what happens tomorrow when i do what i gotta do to get this crap back to were its doing what i want it to do.
