Ive searched and found alot of threads on how to hook up my A/F ratio gauge but noone seemed to state what wire (from the o2 sensor) to use, mine has the 4 wires instead of one,(2 black, 1 white, and 1 green) does anyone know what wire i tap into? thanks

Is this a wideband or just the xmas tree light wanna be?

What brand? Usually most guage makers will have a .pdf file of their installation instructions for various gauges they sell on their website.

Whichever wire corresponds to the white/red on the ECU side of the plug harness (for OBD1, you didn't tell us what car you have).

Narrow band O2 sensor gauges are actually quite useful. Just as useful as a oil pressure, water temp, or oil temp gauge. Basically it's there to warn you to let off the throttle if you run lean under heavy throttle high RPM. Do you need to know exactly how lean? Do you need to know exactly how low your oil pressure is, or just that it's low?

Just because a narrow band O2 can't be used for tuning doesn't mean it's useless as a gauge. People should try to keep their information straight and not just jump on the bandwagon.

 

the brand is FAZE..got it from auto zone, it came with instructions but not what wire to tap into thats why i was asking this...

 

i have a 94 gsr integra so OBD1

if it's not a wideband don't bother putting it in. return it and get your money back. what exactly are you going to get out of the gauge?

Some people like them because they will tell you when you "lean out" so you can let off the gas to avoid further damage.

I personally think its BS and you should go get a wideband they dont cost much more and you can find alot of one that were only used on a dyno for tunning so that makes them even cheeper.

Oh yea you want to tap into the green wire.

 

Thats an awesome writeup right there.. one more quick question, for a turbo application, what gauges are needed...right now I have a boost gauge and an A/F ratio gauge..what other gauges should I be looking to get?

it's normal for a car to 'lean out' under certain conditions, that's just how a car runs. air/fuel gauges are worthless unless they give you an exact number.

personally i have boost, oil pressure, and oil temp. in my opinion a wideband o2 is just as valuable as a boost gauge but i don't have the cash for it.

Do you have a horrible tunner or are you just talking about how it leans out when you let off the gas? I would like to know these certain conditions you speak of that a motor leans out and its "normal".

no, as far as i know my tuner is a-ok. a buddy of mine has an autometer a/f gauge in his civic, it doesn't tell me ****. it shows me it's running lean when i let off the gas and rich when i redline it. that doesn't tell you anything at all; you need numbers to know how you should adjust your fuel. fortunately for my buddy his engine is basically stock; in my case i'd be fucked if my tuner was trying to tune my car off that gauge.

But it still tells you when you run lean doesn't it? It doesnt tell you in such a "wideband" but it still tells you. No car should ever run lean unless your letting off the gas. And yes your buddys gauge does tell you something, if your redlining the car and that gauge turns red/lean are you still gonna push it further?

no, it doesn't give me any useful info at all. how lean is lean? how rich is rich? his car runs 'lean' unless your giving it some serious gas. that gauge is 100% worthless. i have a turbo and i will never waste my money on any a/f gauge other than a wideband.

I would say 90% worthless, I'm just defending the 10%. You dont need to know how rich is rich and how lean is lean, you need to know that if your on the gas hard and that goes red you should let off the gas. No it doesnt happen everytime but something could go wrong causing it to run lean and you may not even know it and your car just keeps running lean and soon you have a blown motor because your racing around your car and didnt know it was running lean.

 

what exactly is a wideband o2??

Think of it this way a narrow band tells you only Lean Normal or Rich but a wideband tells you everything inbtween and it is usualy read by a number as to how many parts air your running to how many parts fuel your running.

no need to defend. say it goes lean. how lean? by how much should i adjust the fuel map? when tuning you need numbers, not 'rich' or 'lean'. say you're running under boost and it shows 'lean'. by the time your gauge reads 'lean' your engine is probably toast, it doesn't take a lot to cook it. the gauge reads 'lean' under extremely lean conditions; if it shows lean under hard gas you're in serious trouble.

it shows you a number; how many parts of air to how many parts of fuel. instead of simply showing 'rich' or 'lean' it'll show you, for example, '12.0'. that means that your engine is burning 12 parts of air to 1 part of fuel. this is how you tune your a/f ratio; you need to know exactly how lean or how rich your engine is running to properly tune it.

Adjust the fuel map? Who said anything about tunning? Certainly not me. No one in there right mind would ever use a narrowband for tunning. And no your engine wouldnt be toast if you let off right away. It doesnt read lean under exteme conditions you just said it read lean when you let off the gas. I'm done with you. You have nothing for a brain.

your right, a tuner wouldn't be using that shitty a/f gauge to tune your car with, he'd use a wideband. however, what again is the point of a a/f gauge at all? so you can see if your a/f ratio needs to be adjusted. your right, normally it'll only read lean under light throttle or idle. my point is, if the engine runs lean enough to show 'lean' on the little light display know as a narrowband a/f gauge then your engine is running extremely lean; it's not just a little bit off. by the time your gauge shows lean it might be too late to let off. with a wideband you know if your a/f is off even by a little bit and you can do things to prevent engine damage, such as let off the gas and adjust the a/f ratio at that point whenever you get a chance. you obviously know what you're talking about.

What is the point of the idiot light for the oil?

Why even bother having temp gauges?


You're going Waaay more indepth then you should be,
it's simple as, if you're on the throttle a lot, and it starts going lean,
then that means something is fucked up, and you better go easy on it til you figure it out.

Simple as that .. It's a narrow band, don't try to complicate that fact.

The only valid point in that whole mess that you call typing was that "its too late to let off" but its really not and your stupid for thinking that and it doesnt take half a brain to realize your wrong.

are you serious with your questions? you should already know the answers to them, they're really pretty obvious. if you like the light display the narrowband a/f gauge puts on then get it, just don't get it thinking you're going to get something useful out of it.
