Air/ Fuel Ratio gauge

So wait a sec.... my split second led on my steering wheel column is bs????

if you have a narrowband sensor, yes.

What is it connected to?

This:


Might give you a ROUGH estimate as to how your engine is running.

As will this:




However this:


Is a useless piece of crap that is sold primarily to idiots who believe that they need it, and ricers. (did I repeat myself?)

Also, if your an idiot light kinda guy, what in the hell are you hoping to accomplish IF this did in fact give you any kind of usable information? I betcha your gonna "tune" your AFM to fix it right?

The point is, a air/fuel guage on a narrowband is at least 33% accurate, seeing as how there is 3 readings. So it isn't pointless. So a simple wire colour would have sufficed instead of rediculous replies.

yes it is pointless, because it's just going to bounce back and forth and show you nothing. a narrow band can read 14.7, it can't read any other AFR.

if you really wanted to know, you'd use your brain and find a wiring harness chart for your car and figure it out yourself.

if the light comes on then your motor is already screwed. A gauge shows the pressure droping not just "ok" or "not".

[Borat]

which is why there is an idiot light on the dash which you are likely to notice before the gauge?

[e30Matt]

Especially on one that's 20 years old. Never.

[asubimmer]

yeah a oil pump would never fail on a stock motor and cause the pressure to drop....

[DaveSmed]

First, how the hell do you expect to help you figure out why your car is running like shit, and second, voltage and oil pressure gauges useless? You new to the whole car thing?

[SamE30e]

Nice, now can I use a alligator clip to tap into that sucka or should I t into it? Or will be be the most inaccurate thing ever that has been in cars for 20+ years that I assume are the most pointless part on the car next to the brake lights.

[asubimmer]

its the useless color...

[SamE30e]

Holy shit. Is this a fucking BMW forum or Volkswagen?

It's a simple question that requires a simple answer. The question was "What colour is the o2 sensor signal wire" Not "Do you guys think that I should put a narrow band o2 sensor guage in my car, if so let me know the colour of the wire, if not dick me around and give me your opinion as to whether or not it is useful or not?"

I'm pretty sure that a good amount of people in here have a useless gauge or two, for example does anyone here have a volt guage or oil pressure guage on their stock motor?

It's alright guys I figured it out.
