help me install my electrical Air/Fuel ratio gauge?? please..

[91nissantwo40sx]

I recently just ordered the Prosport Performance Air/Fuel ratio gauge and they just came in today. This will be my first time installing anything on the car since the last owner has done everything for me already. Heres my engine



I will try my best to put everything in the proper position but im gonna need your guys help cause i dont want to screw anything up. I will read the instructions that they gave me and i will post more pics later for you to see how far ive gotten!!

is it an actual wideband? Or is it just a gauge that is supposed to tap into your existing 02 sensor? If its the latter then i wouldn't have even bothered to buy it in the first place because its going to be inaccurate.

iirc, white wire is signal for the gauge.

Exactly, wideband or why bother. The wired AF gauges are only decent for NA.

im not too sure if its a wideband or not.. hopefully it is but i dont think it is because it was only $50?

well how bad is it going to be?

[ILikeMy240sx]

Its not bad... its just useless. Narrowband O2 sensor is good at running very close to equivalence ratio of 1. Meaning the stoich ratio of gasoline which is 14.6. It can't monitor A/F ratio like wideband O2 sensors do which has linear voltage output as a function of A/F ratio. Narrowband O2 sensor just outputs one voltage for something leaner than stoich and another voltage for something richer than stoich so with narrowband you can't tell whether you are running the correct A/F ratio you need.

That's why you will see narrowband A/F gauges just jump back and forth between lean and rich during part load operation and just rich during heavy load (WOT).

With wideband O2 sensors that can actually tell you what your A/F ratio is will not jump back and forth between lean and rich but rather tell you the exact A/F raio.

Cliff notes: Narrowband O2 sensor gauge is as good as a disco light on your A-pillar

^^^^ Kool I'm going to install one in my car, so I can have a light show going on as I dance to my trance music as I drive

Yup, I have one - fancy autometer - total POS

where can i buy the autometer wideband. can never find it. autometer.com dont sell it. got to find a dealer.

wiat. doesnt a wide band require another hole in your turbo extension. or ar therer differnt kinds.

yes it requires another bung.

[idahotuner]

AEM sells a wide band that i am planing on getting. phase2motortrend , heavythrottle, 240sxmotoring

Man, I got to get rid of this thing now! Is a EGT gauge better?

[Emperor_Tha]

yes it requires another bung.

does the kit come with a bung to weld in?

Or you can get a wideband w/a narrowband output that replaces your stock o2 and has a wire that runs to your ECU for the signal.
