Thread: What works best AFR's to aim for at different loads?

Hi team, what are the guidelines for the best / ideal AFR's for the load points?

After values like around mid 14s for light loads, low 13s for mid loads kinda thing.

Any help would be greatly appreciated.

Turbo or N/A?

heres a little something for turbo..

Sorry, should have said, it's N/A.

14.7 cruise an prob low to mid 14 part throttle an 12.5-13.4 wot...

Dyno is best way to find what your setup wants

Cheers!

Would love the dyno time; wishful thinking.

Dyno tuning is honestly the best option.. They dyno tuned mine to around 12.8 / 12.9 at 5k then at 6.5k goes to 12.5/12.4 then at 7.3k to redline goes down to 11.8 for WOT (my b14 in my sig)

My ve na liked 13.1 wot all the way up

Yeah I noticed they wanted to richen it up at the higher rpms, never even tried 13.. They leaned it out to 14.5 or something stupid then just went rich to 11.8 lol I wish I could tune it myself honestly... At first they got 158 until I told them to put the timing back where I had it and that got to 173! Lol

I think I started at 12.5 an leaned it out to 13 where I gained some power, by 13.4 it went back down so landed at 13.1 or so, did that before an after vvl I believe but its been 3 years lol

Lynch is right 13.1@ wot with the stock compression VE makes the best power. higher comp 12.1 for sure.
