Im putting in my air/fuel gauge and was wondering if ne one knew where the best place to tap into the red,black, and O2 wires at.

 

Where the engine harness connectors connect to the chasis harness would be easy to get too . Do you have a 4th gen or 5th?

 

you can pin it at the ecu, or the white wire on the o2 sensor itself

 

do you have a wideband? otherwise it's just a nice little light show...

 

i dont think i have a wideband---it might however, 4th gen lude

 

no thats a narrowband a/f meter. hope you didnt pay a whole lot for the guage because like bb6racer said its really just a pretty light show...

 

it doesnt make an accurate read from rich to lean at all?

 

your stock O2 will only tell you if your R/F is greater than 14.7:1 or less than 14.7:1, it will not tell you how much greater or less it is. Thus you never know how rich or how lean you are.

stock O2 sensor is very much like a digital signal, either zero or 1 volt. It can be somewhat useful in that if your lean at WOT then you know something is wrong. As far as knowing how far off you are, and for tuning use it's crap.

 

hmm i guess then merry christmas, its goin to b a light show

 

Very true. Especially the autometer A/R gauge. A complete waste of money. as far as these gauges go, the Greedy one is best, but like bb6racer said, unless its a wideband, its kinda useless. Wideband o2 meters are expensive, and have a limited life. The sensor I use on my MoTeC has a life span of about 25 hours I think.

don't some cars come w/ wideband o2 sensors? i've never heard of a 25hour lifespan.

 

no, no stock car comes with a wideband 02 sensor

wrong...
civic vtec-e comes with wideband NGK, some vw also (bosch and ngk).

 

are you sure about that?

just because its a 4 wire doesnt make it a wideband, it's just heated.

only hondas with wideband sensors are the new cars with k series engines.

 

i'm almost positive that the hx civic came w/ a wideband, which like pentaq said had the vtec-e.

uhh i think heated o2 sensor are probably on all obd 1&2 cars.

 

yea, most likely, especially on obd2. my 7 orginally came with a single wire type.

they are 5 wire sensors.
