just used my innovate wide band on my car.
i have a b16a

edelbrock intake manifold, short ram intake, 2.5 straight pipe(no cat)
aem fuel rail, fuel pressure reg.

i read 14.4 on the wide band at idle
and then i took my vacuum hose off for WOT(wide open throttle)
and i read 13.7 at WOT

i dont have a EMS so i cant tune in increments but this is a drag car so what a/f numbers shall i try to reach to maximize power????

 

I'd try to get it a little richer, maybe in the 12.5 range, but every car is a little different.

 

arent you supposed to run leaner to maximize power without detonation

you think if i run richer it will maximize the power?

Yeah, I can't remember the exact # for max power but I do remember that it was 12.X...My Si motor runs about 11.8-12.2 AFR WOT at redline.

 

There is no exact number for max power. Every car runs different and should be tuned accordingly.

 

well i dont have a dyno

but do u think on average that 12.5 a/f will post better numbers than 13.7 at WOT for my setup.

Around 12.5 at WOT is a good starting point..

Good answer! for me. Most cars seem to do best in the 12.X range though.
