Air/Fuel ratio guage

[NightWolf]

Im trying to fit an Air/fuel ratio guage that i got from a friend but honestly im not really good with electronics, can anyone give me detailed instructions on how to install it and where the three main wires go

[trickedout420]

1 taps into your 02 sensor i think, the other grounds and another to a power source

[scott288]

you will have to get a wide band o2 sensor for it to work right.

a wide band would be a nice addition for a CONTROLER but for a gauge it's unnessessary

u only need a wideband o2 when your make good power or any turbo car but a 1 wire o2 is fine for a stock motor,the purple wire is o2 and positve and ground just my 2cents?

[MartinGouda]

ok, why do you people think an o2 sensor makes hp now?

a wide band is only useful for TUNING a car to make hp, but with out the ability to control your air and fuel maps there is no need to have a wide band reading of your air fuel ratio. frankly even then there is not often a need. but once you have the ability to tune your air fuel ratio's manualy live in the car, and you have a data logger and you have a significant amount of time to learn the software. then it's worth seeing the gauge work so you will know where to look in the tune but until then the only point of having this gauge would be because you like to have cool toys in your car or because you fear that your oem stock bullshit maps are going to fail you... and that would never happen... the whole point....you don't have tuning then you don't need the gauge or the o2... but if you do have tuning then sure htey help but really why would you be asking about how to install the gauge, you'd be a full on tuner and you would be raping newbs and telling people what they do and do not need already while insulting people while you teach them based on your bitter hatred of people asking questions of you that google could have answered for them.

a wideband O2 can travel more voltage to give a more accurate reading on a wideband A/F guage.

[Wiseco]

this is the best little peice of technology I ever bought.

So far, its accurate, works well, looks cool, affordable... excellent tool for tuning.

Back in the days, I had an air fuel guage on my basically stock car. Its totally useless and gets more annoying than anything else.

no it can't... it's accuracy isn't taken into account by a stock ecu, if you'd shut up and go do some aftermarket tuning on an ecu or on a piggy back you'd know that most people can even run obd1 cars with out an O2 at all...

seriously... stop arguing, with out a controler widebands are bullshit, period

what about that digital gauge with a wide band is any better than a narrow o2 and a bullshit gauge?... you should have spent the money on a uego or something useful that allows adjustment unless you have motec or somethign in the car i don't know about

No what can't?
I know most vehicles can't run without an O2. I said that if you want to use a wideband A/F guage in a vehicle you are going to need a wideband O2 sensor, because a narrowband does not allow the range of voltage that is required to accurately track on the guage. But if the person is using a narrowband a/f guage it is not a problem, because they only read lean, normal, and rich.
And I never said anything about controllers. Maybe put the drugs down so you can comprehend what other people are saying, instead of getting into big rants that are off topic to the post you are replying to.

[wil_wil2]

here is an example of a narrowband a/f guage


here is a wideband a/f guage


Is that easy enough for you to understand, martin? Or do you need me to explain how they work too?

Pull the plug off and see. Car will run, not very well but you can get from point A to B. I bet even OBD II will run too. Without O2 the ECU will go into "safe mode" and dump more fuel then it need.

Both wide and narrow band sensor sense FULL continuous lean to rich range. Problem with the narrow band is NOT voltage range. Its the non-linear respond. The voltage output change very fast from lean to rich. Wideband is design to have linear voltage output from lean to rich. You can built a ECU to read a narrow band as accurate as a wideband, it just need to read a lot more sample in very short time (high sample rate and high resolution). It also need a map to translate the reading to Air-Fuel ratio. Both means more expansive ECU due to speed and memory. A linear sensor require a more simple ECU. Only a equation is needed to get any ratio from sensor reading.

BTW The gauge you posted is NOT wideband.

You're the one need to drop the drug. Stop posting out of your ass.
