installing my air/fuel guage question on signal wire? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Jtuned S13 · 01-21-2008, 06:18 AM

so i just installed my a/f guage all wire hooked up except for one.. the signal wire that allows the guage to read the o2 signal..is it best to splice into the o2 wire itself or spice in to the harness that connects to the ECU???

btw since its a 93 kade the o2 sensor only has one wire coming out so i know its the signal it grounds it self when installed

it doesn't matter, since the reading will bounce all over the place anyway, getting signal from a narrow band O2 is pretty useless.

get a wideband, i know they are expensive but dont you think its better to have something that actually helps instead of having a disco show or a rave party inside you car?

Get it from the ecu harness, close as possible to the ECU.
If your tuning you need a wideband, but for wot you'll know if you go lean at 4grand cause your blinkity blink blink light show will tell you. Anything between idle and full throttle just add music

unicoladron · 01-21-2008, 02:28 PM

yeah, you can install your a/f gague to compliment your collection of boost, oil pressure, oil/water temp gagues to make it look pretty. on a narrowband o2 sensor, just like stated above, can only tell you if you are rich or lean. the condition of your spark plugs can tell you that. a/f on narrow band are useless, but those full swepp LEDs look pretty cool tho.

i know this may soung stupid i got my hands on the fsm it say the the 02 signal wire is pinout number 19??where the hell is that im looking at my ecu and ya its white wire to but im still confused

Just look at the picture in the diagram, one. You know you're looking at it the right way because one side will have 8 pins across while the other side has 7.

hopefully this will help you out

Jtuned S13 · 01-24-2008, 09:56 AM

thanks wonderbread..for the pic i got it today via my email...im thinking for now ill have the light show..til i get more money for wideband a/f guage at least i know where to look for o2 signal wire lol thanks again

duffman1278 · 01-24-2008, 02:16 PM

Picture doesn't work

Edit: My comp was just being stupid

Jtuned S13 · 01-25-2008, 01:46 PM

no problem thats why i joined this for guidance and to give guidance lol

BoroDrifter · 01-05-2009, 05:03 PM

So I know I am running lean, but I am wondering where/when. Will a narrow band be at least accurate enough to tell if it is leaning out on boost or before? I have one laying around...may as well.

JeremyR · 01-05-2009, 05:24 PM

a narrowband is about as useful as a blindman with a flashlight in a cave.

Exactly. A narrow band O2 sensor reacts so quickly you won't have time to monitor it. Get a wideband, learn it and love it.

BoroDrifter · 01-05-2009, 06:23 PM

thanks, just wondering if it would even be worth the 5 seconds it takes to install for diagnosis purposes. I'll get an AEM uego
