KLZE n/a WIDEBAND afs?

[hgallegos915]

Im confused.. hats the optimal af readings? what should it be at idle?


what about under accel? and cruise?

this is on a NON turbo klze.

I removed my turbo kit.

Driving around normal doesn't really matter what it reads, same with it at idle. The main thing is wide open throttle you want it to be about 13.0 or the closest to it for as musch horsepower as possible for a N/A Motor.

13.7 IIRC

[solo_ryder]

Yea, I am sitting at 14.7 for idle, 12.9-13.9 for WOT and cruise just stays in high stoich

[hgallegos915]

Im around 12 under accel, at idle is like 13 and cruise is around 13- 13.7

i have my fuel psi at 15.. i think my afpr is bad..

i think..


thanks for the info

13.7 is way too lean for all motor.

13.0 is what all tuners consider the optimum all motor air/fuel.

[hgallegos915]

when the engine is cold ig et around 10 afs and 12s cruising. under accell its 13. ill richen the mixture more.

whats stock pressure set to?

[Slammed6]

Yeah when the car is cold it will run richer than normal.

[hgallegos915]

ok I was able to bring it down to 12.9 , i adjust it a bit richer and it goes down to 11.

Im using a cosmo afpr however I dont think the gauge works.. so im basing it under the wideband.


The fuel pressure gauge reads like 15 psi then when i rev it goes up. I lowered it to zero psi and the car still runs but studders.. of course im not stupid to leave it at zero.


So i set to 15 and my afs are 12.7 underawot. Now i can burn rubber lol


The car was running at 10 af under w00t I was like at this so called 25 psi fuel. I have a walbro fuel pump.


I think i got it now..
