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?

you need to follow the complete right up of the Auto Tune tutorial and the final steps will be opening your stock tune and modifying your spark tables and copy and paste your VE table...and what not...just download the auto tune file and then set your car to run the AFR you want in the PE table.

I'm still working on dialing in my VE table so I have yet to get this far but I read it and thats what you do....the tutorial tells it all.

Maybe your wideband was wrong/calibrated wrong and you need to reset it and re-dial i your VE table..didn't think temp made that much of a difference
