I want to get a "Air fuel" gauge. How would I go about installing one I realy have know Idea.

Have any of you installed one and how hard is it?

 

I just got one to off ebay with no instructions, i would like to know also but im sure i could just search for it! But any info will help me to

 

Honestly, if its not a wideband, take it back. You can buy wideband A/F gauges for around $120.. spend the extra money.

Any of these should work.. http://www.jegs.com/cgi-bin/nc...r=850

Something like this...

Worth the extra money for accurate readings.

 

I did a search, but all I could find is people having problems.

How does it connect to your O2?

 

The gauge has red, black, white.

red=ign
blk=ground
white=o2

 

Can a A/F gauge hook up to a exsting OBD0 O2 sensor?

dunno

 

yes it can but A/F gauges connected to any narrowband o2 sensor is absolutely useless.

get a wideband; A REAL WIDEBAND; if you want to know your afr. The autometer/etc afr gauges are just to look purdy and make all kinds of flashy blinky paterns that distract you at night

 

Ok i understand that. But can a wideband O2 sensor be used with a OBD0 FI system? I dont want to drill another hole in the manifold.

Too bad that kit you have shown isnt even a real wideband

Real widebands are 250 bucks over, a easy way to tell is most WB 02 kits use 5 wire o2's. I use the zeitronix WB, its pretty much the cheapest on the market at 280 bucks. You use your laptop to do datalogging as well. Some other cheaper brands are PLX & Innovative

Yup, it aslo makes the girls say "Thats cool!"

 

Does the guage need to be matched to the sensor? Like for instance, you have a DEFI A/F gauge and want to hook a wideback sensor up to it. Will it give an accurate reading?

How about this. Use a factory wideband from a VX hooked up to a DEFI or Autometer gauge. Will this yeild and accurate reading?

I'm looking for a cheaper alternative also.

 

No, that wont work, most gauges for Wideband's are actually digital display read outs.

here's some DIY widebands

http://www.diy-wb.com
http://www.techedge.com.au

It's a little more indepth than just buying a special o2 and plugging it in, In order for it to work right anyways. Once you have the unit you can tune all your friends cars. I have mine so it plugs in the cig lighter and go tune all my buddies cars.



Most NA hondas like a 13.0 A/F ratio & FI your looking at high 11's and low 12's

Great info, Thanks

 

i just want to montor my A/F after the car has bin tuned (hondata) to get a geniral ideia of air fueil. like if my fuel pump starts to take a **** i would like some warning..... is my only choice a wide band like techedg or would some thing like this work http://www.halmeter.com/

 

No, those are are just regular air/fuel readers nothing special at all. Let me give you an example.. a normal o2 reads on a scale of about 1-10 and a wideband o2 reads on a scale of about 1-1000 It's what all dyno shops use when tuning your car.

Jeff

 

actually most narrow bands will read below; at or above 14.7:1.
when i'm at 9:1 afr on my wideband my narrowband is showing just maybe 1 or two green led's (autometer afr gague) and at 14:1 the same number of led's light up.

about all the afr gauge connected to the narrowband is good for is to tell when the car is in closed loop mode as the lights will bounce back and forth.

and as far as widebands hooking up to your stock ecu; it won't happen. BUT the techedge kit has a synthetic narrowband output so you can plug the wideband into your bung and hook up the simulated narrowband out to your ecu. it won't give you as good of gas millage but it'll work and won't throw a code. They're working on code (pgmfi.org) so that you can use a wideband (0-5v compared to 0-1v for narrowband) with a ECU so datalogging will be more accurate and for whatever other reasons you may need to.

but what i've done is i have my narrowband right after the turbo on the downpipe connected to the ecu and i have my wideband sensor farther down the pipe (to keep it cool and because there was room) so i can use both at the same time.

 

What gauge would you suggest I buy if I only have about a $100 to spend on this.


How can this gauge help me tune my car?

Not hatin, but this is one reason I don't have a a/f gauge, the other is nothin is hardly done to the motor.

Don't use a narowband O2 sensor A/F gauge to tune.

I had a autometer and it was really easy to install. gound, power and a signal that taps into your stock O2 sensor. It was not great but gave me an indication that I was running rich. I liked it but obviously so did the rat bastard who stold mine.

save your money up and buy a real wideband if you want to tune your car.
a narrowband was built to work at 14.7:1; it will not and cannot tell you exactly how far above or below you are from that and therefore is useless to tune a car with.

a tech edge kit like the one i have for everything but the sensor is ~$250usd shipped and a sensor is $36 shipped from 1stvwparts.com. The te kit has got rpm, 3 voltage and 3 temp inputs to log with the built in logger or you can hook it up to a pc and log/tune there.

the whole kit comes with:
-controller with logger/etc (you DO have to put this together btw)
-wideband cable
-computer cable
-display
-good support system to use if you **** up.....
-Just add a sensor and you're good to go.

very good kit for the price; or try to find one used or borrow one from somebody for a while to tune with

i have the autometer also, got it for $10. since not all of us have money and some of us just can't save, for some apparent reason. anyway i got it not for accurate readings or tuning but just an "idea" to see if i was running rich or not so i can adjust the fpr accordingly. but if you already have $100 might wanna save it up if you can.

 

RE:i can adjust the fpr accordingly.


What exactly does that mean?

 

if you can find a autometer a/f gauge, 35-40 bucks

you can buy a bosch 5 wire wideband o2 sensor for 59.00 from plxdevices.com
plxdevices.com also sells a convertor box for 35 bucks it basically allows you to use a wideband o2 sensor with a autometer gauges, hook the wideband into that box, and from that box hook it up to the gauge, = cheap wideband gauge

 

That is awsome. Pretty and effective.
