Thread: A/f Ratio's HELP!

I have a 94 se-r with a w11 avenir. Right not its on 10lbs i just put in my wideband. Im tryin to figure out what is some good afr's like at idol, wot, etc.
I have a safc2 installed but i dont know where to go with good afr's any help welcome!

Thanks!

i have a u13 ecu, u13 bluebird sr20det on 9lbs, with a b14 bored maf, im untuned and i see mid low 13's from 4k to 5500 and then it drops down to mid low 12's to redline at 7k.

idle you want to be about 14.7-15.2 or so, WOT you can be in the low 12's until 3500 or so then you might want to put it in the high 11's to be on the safe side from there till redline. Gives you a good safe tune that you dont have to worry about.

For your low throttle and crusing you can put your a/f's in the high 14's low 15's for the best gas mileage but just make sure when it goes into boost that it drops down where it needs to be.

Have fun.

Awesome! Thanks man

you might wanna get those 13's into the low 12s high 11's. 13's will make you loose your motor!
