View Full Version : Autometer Air/Fuel Guage..?? again.....
I know we can all pretty much agree that this guage is absolute junk when trying to get "Accurate" readings. My question is, will hooking up an aftermarket O2 sensor (Autometer has one for $99). Will it improve the accuracy of this otherwise useless guage??
I have had my guage for nearly 6months now...sure its eye candy...but now that I have my NX kit, I kind of want it to actually work incase I run into any problems....!

yes it is eye candy but it works...it runs off of the signal wire...get the greddy one you have to put a hole in exaust, this sound like what you are looking for.

IMO I would just sell the autometer one and get the greddy gauge..

actually... i found out there's another wire that you can tap into from a different 02 sensor... i'll take pics and videos tomorrow

If you want accuracy get an EGT, this reads the gas temperatures which is far closer to what is really going on than the A/F will ever give, I have both and when they read different I only look at the EGT.

Umm.....I have the Autometer gauge but I don't see why you say it's not accurate. It's just as accurate as the Toyota scan tool. If you say this because it's constantly switching back and forth this is because the 02 sensor you tapped into (hoping you tapped into the #1 sensor signal wire) works the same way. Your ECU is constantly adjusting from rich to lean. Take mine for example. Under normal driving it never goes into the rich area but always goes all the way lean. This is the range I usually see when not at WOT. This tells me the car is running rich. So if it was going all the way into the green(rich area) and never going into the red(lean area), then this would tell me the engine is running lean. I find this gauge is just fine for reading AF ratio.

russ it sounds bad ass, but I can't see it. i am using wmp.
00CericaRuss - Nice vid. :)
Now please tell me what wire you tapped into!! My guage is ALOT more bouncy than that...its friggin annoying to tell you the truth.
I tapped the line on the passenger side, under the carpet. Where is that one from???

if you pull the carpet back.. you'll see the wire you tapped into going through the floor, and towards the back of the car, maybe 6", there's another one... I'll try and take a pic for you one of these days
funny thing is.... if i screw w/my afc settings, i can't notice much... i guess i gotta try and "tune" it a bit w/the camera for data logging

wait wait can somebody explain this to me..i am about to buy some guages and somebody told me that the R1 Air/Fuel guages were better....but anyay i still got to decide on that..but my quetion is are these hard to install and what are u guys saying about wires under the carpets and stuff....doe shtis mean when i install the A/F guage that i am gonn ahve wires running under my floormats or something....clear this up please
Well where ever you decide to mount your air/fuel guage...you will have to feed it a power and ground. After that...you need to tap the o2 line in your car. 00CericaRuss has found what seems to be the ideal place to tag the line. And no, you wont have wire under your floor mats...well, only if you decided to do a half ass job.
There are plenty of places to hide the wire there...when you try to install your guage, you will see.

sorry bout the delay on the pics... i had a very, very busy weekend... I'll try and pull back my carpet this evening and take some pics

ok... hope this makes sense to you
Cool, that should help a few people out!
I went ahead this morning and went looking for that line...without seeing the pics, I was hoping it was easy to find...and damn it, it was! lol
I cant believe I didnt see that before when I first installed the guage. After switching the wires, I took my car for a run...damn, unreal how diff the readings are. Now it doesnt dance back and forth...it stays solid 2 bars into rich.
Thanks for the heads up on the new location...much appreciated!

no prob dude... now the question is, is it a better reading... i should look in the electrical service manual next to me
