So i got this a/f ratio gauge from my friend for free and he doesnt have the instructions, how would i go about hooking it up?

 

Here are some general instructions for other cars...I am not sure if these will work for the maxima...

really, don't even bother it's totally worthless unless it's hooked to a wideband o2

 

I just searched and jeff said the same thing...

well the format of the post is clearly a Shawn trait.....



but otherwise



edit: and it would be even more worthless to hook it up to a wideband.

 

to clarify, I meant a wideband gauge (he didn't mention what type) with the coresponding WBo2

 

Isn't it worthless either way unless he has something like a SAFC

it's as useless as a tach , a temp , volt, or gas gauge.
you could do just fine with an idiot light, but some people like to know what's going on

 

Why would it be worthless?

 

Try reading the links provided for your benifit, in your own thread........

 

Because, all you have is a gauge. The stock o2 sensor can only pick out a/f ratios near 14.7:1, which is nearly useless. To make the gauge accurate you need a wideband o2 gauge. Then that gives you an accurate a/f reading. But what can you do with it? nothing because you dont have an engine management system that lets you change your a/f ratio. Unless you buy a S-AFC II. But all that would run a couple hundred dollers. It'd get you more power and possibly better gas milage though.

the A/F gauge is handy for determining the load on an engine and could help you adjust your driving style. It is useful to a degree, just not for specifically determining the engines mixture.

 

oh yeah what do you think you may do with it or you think that it would make your car look fast or something.
