o2 gauge install help

[PSYKO PHOENIX]

o2 gauge going in on the weekend, how do i do it? any tips?

do i just solder the wire directly to one of the o2 senders?

if so which one? and how?

ive never done it before and neither has my mate whos helping me hasnt done one either wanna get our shit strate before we attempt it

[ephect]

doesnt matter which O2 sensor you hook it up to, all that matters is u'll know if they're not working once the gauge is connected. the gauge should have 3 wires, neg, pos, and feed wire.

you have 2 options where to hook the wire. you can run it to the ECU and solder it to the wire at the ECU, or run the wire into the bay, and solder it to the wire just before the plug.

i got lazy coz i cbf'd running it behind the dash to the ecu so i ran mine to the plug in the bay.

In the bay: voilet wire on the passengers side O2 or Grey on the drivers side O2.

ECU: D15 is voilet and D13 is Grey.

i have a plug pic in my thread in the how-to section: How To: Fix the VS V6 4 Wire O2 sensor earth problem – Known Holden Problem

sweet so i just run it into the engine bay and splice the gauge wire to the wire coming from the o2 sender

is it better to run it through the ecu or strate from the sender?

im guessing both senders will be the same (have the same mix of fuel and air)

Do you have a wb 02 sensor installed? Without one it's probably a waste of time as you will be off scale whenever your ecu goes into open loop.

what do you mean by a WB?

what do you mean by a WB?

Wide band. Stock standard ones are narrow band.

Reaper

[PSYKO PHOENIX]

not sure, its an after market one by proplus, cant find any info on weather its wide or narrow band, whats the differance?

[Reaper]

How much did you pay for it? (Thats a good indicator).

Yea as reaper said, all it'll do with a narrow band O2 sensor, is give you cool looking LED Lights they don't really give you a fair indication plus the fact that its changing so fast you'll be pressed to read it, I used to have one in my old car was just spliced into the factory O2 sensor mine had 4 wires I tried all of them till I got a reading on the gauge.

Below is a pic of the one I had Its the top gauge on the pillar, all that used to do is run up and down (rich to lean) and jump around no actual decent readings

i payd $70 for it

heres the web link

not the gauge itself but the Oxygen sensor, as I said if its just a factory one which I'd say it will be, as Wide Band ones are expensive like $130ish plus I don't think you can just throw a wide band sensor in your car is they read different and have different outputs youll get what I have said above, not actually a decent gauge but a xmas tree gauge.

Hook it up all the same just don't expect to be as useful as most other gauges.

What about the sensor???

Reaper

[PSYKO PHOENIX]

i want a decent gauge lol

so how do i get and install a wide band gauge, cost etc?

[PSYKO PHOENIX]

as far as i know its a stock one

Did you read any of the links I posted above

Reaper

[PSYKO PHOENIX]

hahaha sorry no, i will do that now, im at work and my boss keeps walking past every time i look at one of them

pain in the ass

standard O2 sensor in your commodore is a narrowband sensor. it's job is to aid fuel economy by keeping your AFR's in the correct operating range when in closed loop mode. it will swing the AFR's backward and forwards through the stoichometric AFR of 14.7:1 as that is basically where the engine produces the least amount of polution and you get a good clean burn. if everything was opearting correctly in your car you would expect to see the needle swings accross the 14.7 position continuesly (when in closed loop mode). when you mash the loud pedal the ecu will go into open loop mode (i.e. it runs off the figures in the fuel map) and will actually run richer as this is where engines make more power, around the 12:1 AFR. some people re-tune there cars to run lean in cruise mode which reduces fuel used but this produces bad exhaust emmisions.

that is the basics. there is a bit more to it but then you need to start reading those tech articles

cheers bro!!

so i can install the o2 gauge on the stock sender and then when i can afford it upgrade to a new wide band sender?

Yes..... but the measurement would be pointless. Why bother?

Reaper

[PSYKO PHOENIX]

to get the gauge in and working, then next pay upgrade the sender to a wide band one

Thats what I was getting at.

[ephect]

the only thing i can see as a problem with this is the ECU not liking what the wide band sensor is feeding it. they have been setup with a narrow band sensor for a reason. Guessing you will need a tune to suit a wide band after you install them. dont know for certain, but seams logical.

[immortality]

95% certain that the standard tune won't accept the input from a wideband O2 sensor without modication.

[PSYKO PHOENIX]

what about just adding another one??

eg buy a wide band sender, drill a hole in the esaust and stick it in, would that work?

run it as a stand alone sender/unit?

[ScoHar]

But to sum it up, yes you can fit that gauge to your factory O2 sensor. It will work but won't be much use, but will look cool.
