A/F ratio guage

[road rage]

Anybody install one and how easy is it?

easy! but you need to weld a bung into your exhuast for a O2 sensor. If you have MIL's I don't think you can tap into your existing ones, not sure though.

the mils effect the rear o2's only. you can get signal for the gauge from a pin at the computer although i'm not sure what number it is. with that being said, the typical a/f gauge from autometer is nothing more than a light show. unless you just want some pretty lights bouncing around dont bother.

Let the "buy a wideband!" comments begin!

right now he really doesnt need either.the autometer one is useless and the price of the widebands being what they are, it would be a waste of money for him right now.

For the $450-500 it would cost for a wideband O2 gauge, you could get on a dyno many many times. If you plan to do a lot of tuning on your own car, then it might be worth it. Ask yourself how many times do you expect to adjust your a/f ratio, then do the math.

very easy install... you can either go to the PCM or do what i did and run it through the firewall under the car and tap right into the o2 sensor... on my 04 it was the black one

this may seem like a dumb question but can u just get a a/f gauge and tap an other o2 farther down the exhuast. and i think if that would work it would be cheaper then getten the real deal.

You can get a wideband for as low as $300. But there are really only two reasons to have one. Self-tuning and a safeguard if you are running a power adder.

you can tap into O2 wiring. But like others have said it will only tell you if your stoich

Defi makes a great A/F gauge for short money
