question about afr...not the heads, the ratio. hey all i am curious what everyone thinks is optimal for afr on a NA engine that is internally stock with just full exhaust and a lid?
What would be a good timing curve for this as well? max timing?
i am trying to figure out how i should have my car tuned now that i have EFIlive and i figured this may be a better place for actual engine data.
thanks

BTW i included a pic of my commanded AFR range that i am using now. open to info,
at idle just sitting at 800 rpm i am sitting at right around 14.5AFR

13:1 to peak torque, 13:2 to peak power, that has worked well for me and a few others, but whatever your car likes the best is what you should run....the commanded afr dont really mean anything if you're not hittin it
