I am running a 2002 custom O.S. with my twin turbo setup. I have the AFR map setup like shown in the autotune tutorial with 14.7 all over except the WOT. I still don't understand the reasoning behind this. I have logged my actual AFR and changed my VE table so that my AFR matches What it needs to run correctly. These figures are different then the 14.7:1 ratio. Do I need to return a setting so the computer will compinsate for weather temp?
All mu tuning has been done when it was 80 degrees out. Today in the low 50's It was running lean. I had to lean the entire wot VE table 7% to match the AFR ratio's when it was 80 degrees outside? Can anyone point me in the right direction?
