air fuel ratio setting

Post by 86capriasc »

What is the ideal afr? I was tinkering with my eec extender and richened the fuel to 13.25:1 and some of my drivability issues seem to be better.

I think with swapping computers from th a9s to the a9l, the a9l is a more aggresive tune. I hope that is the problem with my stalling at idle.

For a stockish naturally aspirated setup 13.0:1 is nice and safe. A higher compression NA combo I'd like to be 12.5:1 and a supercharged combo around 11.5:1
