check it out: $140 wideband o2 setup

[wdwalker]

check it out guys, i just figured out how to set up my own wideband o2 sensor setup for really cheap. here's the ingredients list:

$50 on ebay- AutoMeter A/F Gauge (ignore initial reflex to flame, keep reading you'll see...)
$55 - bosch wideband o2 sensor, and finally
$35 - PLX M-Series AutoMeter Narrowband to Wideband Gauge Converter
=$140 total

what this lil device does is converts the normal narrowband signal that the a/f meter usu. gets from your o2 sensor, and converts it into lambda. so you'll be getting a true wideband readout, not a guess from the stock o2 sensor.

I did that too its not in. But its a GREAT idea makes a A/F gauge useful.

good post mate!

So do you replace your stock o2 sensor with the wideband, and then use the converter to feed both the gauge and the ECU, or do you have to weld another o2 bung on to your exhaust?

edit:
Those prices seem awfully low.

or you could be a baller weld in another bung and have a plx m500 like i did.

But good post we did this once on a guys car here. Good cheap and effective.

junk.. af meter is just a bouncing light
id rather have a real time number display and something that can datalog

plus bosch, mehhhhhh

plx is good, just psend the extra and get a worthwhile product

junk.. af meter is just a bouncing light

it is only a bouncing light with a narrow band, with a widband, it is steady
a narrow band only sends 2 signals....rich and lean(but in voltages) a narrow band sends measurements so an a/f guage wont just bounce, it will give actual readings

 

[banzai]

AEM has a wideband setup out with a digital gauge that gives you the actual a/f ratio 450 bones though

 

[wdwalker]

crap i just looked into it some more, and it turns out u have to have the wideband controller to do this... meaning its ridiculous to get a a/f gauge when u can just get a led readout for less than $50 more... so im gonna end up just gettin the M300 kit from PLX, its only $329 + $10 shipping. i think thats the next cheapest option i have... anybody know a cheaper way to tune??? (only one i can think of is egt, and i dont understand that tuning method)

^^ like i said
id want a number not a bouncy light that just goes back and forth and i have to actually concentrate and see
id rather have a number that i can see, so i know what range im in

plus nothing to data log


like i said, JUNK

I'm gonna have to agree as well. I call junk cause I rather see a DIY writeup on exactly what your talking about with pictures and such.

 

[wdwalker]

what he's saying is since it has a wideband input, its not gonna bounce around cuz the o2 sensor isnt GUESSING how lean/rich its running. it has a true reading that tells exactly how rich/lean it is, instead of a reading of stoich/not stoich, which is provided by the factory o2 narrowband sensor. only time the light would move is when the a/f mixture is getting leaner or richer, but it won't do the little wave across the screen thing it does on a factory narrowband o2 sensor. anyway it doesn't matter bcuz i just figured out to use it you still have to have a wideband controller, meaning you'd still be spending around $300. for this price i'd rather use a digital number readout than have a readout measured in increments .5:1 per led. i'm gonna end up getting the m200 kit from plx probably, it only costs $299 + $10 shipping.

 

[evan2]

yall arent understanding, i know its not going to bounce around i know what narrow and wide are.. iknow the differences this is me hello

im saying id rather have a real wideband that will give me a numerial display plus be able to data log

i dont want a cheap Autometer guage with a small badn with lights, yes it will say rich stoich and lean
but i want to know what my AF ratio is, not just oh well its rich

or its near it...
i want numbers

that is whay im saying, ok end of post....

 

[racerx661]

my boy has the aem wideband in his crx.....it is one sweet unit.....got it for less than $400 bones though

the way its set up u actually can figure out your exact a/f ratio... to the nearest .5 ... the far left is an air/fuel ratio of 10.0:1, the next led is 10.5:1, the middle (where it says stoich) is 15.0:1, and the far right is 20.0:1 but yeah i get what your saying, it'd be hard to see exactly which led it's on without looking at it/knowing where it is... and since it turns out its not cheaper i'm going the digital numerical readout too...

 

[evan2]

^^ that is far too much work, how many guages have you had to look at while trying to drive? Just curious
its not easy to monitor a bunch... id rather have a real time output and something to datalog

i dont know how many more posts im going to have to say this in, i heard bad things about the aem unit though i do like how the display is so small
my boy has hi EG clock removed and the wideband output showing through there

but its a small unit and it sucked he said

 

[wdwalker]

dude using the clock display for a wideband output is a sweet idea... never thought of that... i still have my clock block-off plate from where i put in a clock off a junkyard civic... and my radio tells me the time... yeah i dont really like the aem unit either, i want the plx one. wonder if i can get it with a smaller display?

 

[evan2]

plx is too big for that, but well worth it
ima get one soon, so ima have to rig something up

 

[Ravage70]

a wideband is worthless without datalogging

 

[wdwalker]

can i not datalog thru the ecu? ive got my uberdata kit coming in any day now... im chippin the p06 to a p28 in preparation for the vtec head im getting, for now im just gonna set vtec real high like 8000rpm/7900 disengage. how can i make the wideband hook up to the ecu's output?
