Air/ Fuel Ratio gauge

ITS THE GOD DAMN GRAY ONE
or is it the black one... i cant remember but honestly you arent going to get a reading, its just gonna go back and forth the entire time it will never rest on a readable number

Thats what I was looking for, and it does rest on a reading when you give WOT, or at least my brothers Audi and RX-7 does.

[nando]

no, it rests on a voltage. you can tell it's richer than 14.7, but you can't tell how rich it is. so it could be 14.6.. it could be 10. you have no idea. that's why they make widebands..

[chbimmer]

if you have an LC-1, just use that.

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

Huh? So you pull over and turn the motor off every time you engine slows becuase your oil pressure will drop?

oil pressure will vary constantly depending on revs and temp. The idiot can actually come on at idle if its an older motor up to temp with a thin oil in it. Doesn't mean the motors fucked. Point is if the light comes on pull over and you should be right.

you said it yourself that it changes....

so why would you turn the motor off just cause it dropped a little? You would only turn it off if it drops BELOW a safe level.

Say no to drugs newbz

[Borat]

exactly, and the light indicates when the pressure is below a safe level.

Newbz? ouch, guess I'll have to make more than 3 posts a week then.

[Borat]

as a measure of my newbness i have fucked up and posted twice.

[e30Matt]

Given that situation, I'd rather know when the pressure was nearing a dangerous level, instead of knowing when it had already reached said dangerous level.

Gauge FTW, light FTL.

Like I said I don't want to cut apart my harness, a cut harness is worth less $$... lol

[asubimmer]

you don't have to put it into your ecu. you can have 2 o2 sensors ;)

[nando]

he doesn't even have to do that - the LC-1 has a narroband output.

[asubimmer]

I am aware of that, he said that he didn't want to mess w/ the stock harness. Although you can leave the stock harness alone and wire it into the plug for the o2 sensor. I had an AEM wideband that also could put out a narrowband signal, but I only used it for about a month and then sold it.

that's too obvious :p

Oh! Now it makes sense! You didn't want to cut apart your harness to install something that would give you a useful reading so you can resell the harness!

....So you cut it apart to install a stupid gauge.

....And you could have used the factory O2 connector for the LC-1.

Damn. So much for making sense.

Actually no. I'm not using to to tune my AFM, I drive an e, it is the definition of slow. Nevermind I found the wire colour, you guys are useless.

Were just trying to give you a feel for your gauge and as helpful as it is. Hey, why not try tuning by r3v, find a thread that blunt posted in and every time someone says penis, thats one vote towards your car running rich, every time a homosexual reference is made, one vote towards lean. Might even be more effective than the gauge!

[delatlanta1281]

Ok I have a question then. I replaced my intake man. gaskets six months ago. One folded in the process and the car got worse and worse. It wasn't running too badly, but my a/frm started showing more and more lean.... I knew something was wrong b/c of the meter and low and behold.... It was right.
So what's so useless about that?
