Air Fuel gauge help

[ESR98civic4689]

my air fuel meter is not working, i tride to hook it to every wire, i have an after market header and htere are two o2 sensors one at top and one at bottom i tried every wire and is reads two reading when its supposed to be only one see what i mean , do you know anything i could do or what wire do i have to hook it up too what color and on which sensor

only one of the wires is a signal wire the other is the ground. you may have not spiced into the wire enough, causing mixed signal... not sure really....if you call autometer they will tell you which wire it is you need to splice into. I only have the one 02 sensor so it easy for me.

the pic you attached isnt linked, i cant make anything out in the thumbnail

not to be a sdick.. but just so you know.. a/f gauges like the one autometer makes suck.. they are pretty useless...

I like to stare at the pretty lights

ya its just a light show. it won't be accurate at all and over time will damage the sensor and alter the voltage the ecu sees. Bad idea unless you install a wideband gauge (that comes with its own sensor).

what company makes those gauges and where could i get them

 

[ESR98civic4689]

and, oc_civic i was looking for a nitrous gauge that i ma buy with the nitrous, is that carbon fiber nitrous pressure gauge anygood from autome ter

THe O2 closest to the head it the primary... YOu tap into the white wire on the sensor.& no other wire... the O2 heater wire green or yellow/black will damage the guage not that its worth a damn anyways.As look as you dont do any turning by it lol. Go wideband

 

[ESR98civic4689]

yea but werhe do i get these wide band guages and who makes them

Any perfomance shop, Ebay... examples of some wideband companys are PLX, AEM, Greddy, ect. I like PLX with digital readout the best.

Here are real A/F guage(widebands)... http://www.tunersports.com/plx-devices-m-94.html

I dont think everyone has enough $$$ to be puttin in wide band ...but yeah they are the best.

AEM UEGO has a sensor and a regular gauge to read from it with leds. Around $350. Also Innovate makes some sort of system. Just search the web.

its worked fine for me.. no issues.. = )

 

[ESR98civic4689]

do you use the mechnaical ot the full sweep electric one

 

[j_fukin_t]

on topic of widebands?? do they have a pigtail that the OEM o2 sensor plugs into and then another pigtail to the gauge/control box?? thanks

 

[gearbox]

you can't use the oem sensor with a wideband gauge. most oem has narrowband.
