A/F gauge going ape shit
i just hooked my auto meter A/F guage up and it just sweeps back and forth non stop. i even drove around for a little bitto see if the O2 sensor had to warm up or something.
is my guage fucked or did i hook it up to the wrong wire? oh yeah i hooked it up to the white one coming from the OS. |
Re:A/F gauge going ape shit
no that is normal. your ECU is constantly leaning out/richening your fuel mix for emissions purposes. if it does that under WOT though, there is a problem.

Re:A/F gauge going ape shit
If you bought the autometer one it will just sweep during idle. While driving the O2 sensor mv readings shold only sweep between the yellow zone or stoich points. Now if you are running correctly, at full race throttle you will be in the green or rich section which lets you know its all good and not going down hill.
If you want my opinion, get a digital read out A/F gauge so you can see just how lean or rich you are ...for instance 14.7:1 as stoich and 11.3:1 lean and 15.3:1 as rich and so on. |
Re:A/F gauge going ape shit
Are the AutoMeter LED A/F Gauges accurate, or are they worthless?
I've heard from a lot of people that an EGT gauge is WAY BETTER than that stupid LED sweeper thingy... Is it possible to see what's goin' on with the LED A/F Gauge? What are the opinions out there? |
Re:A/F gauge going ape shit
an A/F if it is not wideband and not hooked into a dyno are just ball park figures. All you really look for is that the guage reads rich when you WOT it. thats about it. an EGT is more accurate IF you now what temps to look for.

WTF is an "electronic A/F gauge?
BTW: crx88si... Wanna look @ my setup tomorrow night? |
Re:A/F gauge going ape shit
sometimes it just sweeps faster when i give it hell. i'll try and see if it stays around a certain area tonight.

Re:A/F gauge going ape shit
make sure you have a GOOD ground becuase some pud where i live hooked his up and didnt have a ground so his af moved around a lot
|
Re:A/F gauge going ape shit
They always move around a lot unless you are at WOT.
