Hello, been a while. I was wandering about how leaning\riching WOT AFR works?
let`s say AFR is rich and am leaning it 1% by intune, what happens? does it rush more fuel into the engine or less air?
I hope you can help with it


Thanks

leaning commands less fuel....

Along that same topic, say for example your A/F ratio is 12.0:1 and you want to lean it out to 12.5:1. Would that be -5% fuel or is there a correlation between the % and the ratio?
