i dont take any graphs, i use the histogram for all the fuel trims. an no you dont add. fuel trims are a % of fuel. so if you ltft and stft add up to be +10 you want to add 10% fuel to that cell (that is if this is what you are talking about)

My car runs right at 12.7 on the mostly stock motor, i keep it at 12.5 on the junk.Autos and M6 cars seem to respond differently to AFR. Also, alot of people dont take into account ram air setups when setting up AFR, since u dont see its effects on the dyno.Dont want to go too lean on those bansai runs and burn stuff up!

yes this is what i am talking about.... that is the histograms i am using i just didnt know which way to go with them.... so use a calculator and do 10% of what is was and add that to it? if thats what the fuel trims call for of course... i just want to make sure i am clear...sorry for all the questions...just want to make sure i am 100% on this....

for the spray do you setup different ve tables or do you just spray the house down...? how much timing do you take away?

ok, just to clarify, are these numbers you're getting on the dyno or on the street? I've heard cars run about .5 AFR richer on the dyno than the street, so it's nice to know which one you guys are talking about.
