anyone have experience w/ these? I guess they've modified them for more accurate readings.

scroll down past the boost controllers to the guages...

yeah. i wonder if they are any diff..

 

i wonder if they just modified the resistance it takes to light up each led... interesting...

 

You're still limited to the stock O2 sensor's accuracy, which isn't much.

 

save your money and get a wideband

 

Best advice yet.

 

so is anybody using one? I like firsthand info.

 

Your still geting the reading off the stock O2. What's the use? Just a waste of money!

 

Have you used it? Has anyone used it and compared it to real wideband? Dammit. I'm sick of people spouting off info based on presumptions. Sure the stock 02 sensor is focused on the wrong part of the a/f range but this dude's concept sounds semi-solid.

 

I bought one of those awhile back, it works as advertised. A lot better than guessing .75 to .98v with 5 green leds. Its pretty much the same as this one: http://www.gadgetseller.com/gauges/index.htm

I'll sell it to you for $60 shipped, white face phantom series. excellent condition

 

People are not spouting off. If you understood how a wideband works you would know that these recalibrated gauges are not nearly as good as a wideband. The website says right off the bat that the gauge only measures wide open full throttle. I don't know about you, but I need to be able tune part throttle.

 

Have you seen the stock O2 sensor's graph of voltage vs a/f ratio? It doesn't matter what you read it with...you could read it with a voltmeter. It still doesn't make a difference because the O2 sensor's output voltage can be the same for many conditions.



Crappy pic, but you get the idea.

At .9 volts, you could be at 10:1 a/f or you might be at 12:1 a/f. The stock O2 sensor cannot accurately tell the difference.

I don't think he was asking for a debate which is better wideband vs modified gauges. I think the question is "is it more accurate than the regular a/f gauge", the answer would be YES.

The answer if its better than the wideband is NO.



Here's a better pic and it would suggest that voltage goes up as a/f ratio gets richer. I've tested the unit vs my techedge wideband, at .91v I would be around 11.8:1-12.2:1 and at .88v would yield between 12.8-13.0:1. I did not see a big fluctuation between the 2.

 

Are you saying the readings between your wideband and the modified guage was close.

I know it's no wideband, but would you suggest it?

 

hmmm...blown motor and safe motor...hmmmm...

BTW..they are not $1000 either.

 

cant you buy a prebuilt unit from tech edge and then the sensor and the totoal be around 500 to 600ish..or even cheaper? maybe i'm on crack....

 

what about the greddy air/fuel gauge. doesn't that come with a wideband?

 

you could buy a wideband off an oldcvic they are like 300

 

i have 3 new in honda packaging for $185+shipping

 

no, it comes with a regular narrowband

 

which year civic did the wideband come from?

 

92-95 civic vx 1.5 engines

 

are the vx O2 sensors really a true wide band o2 or are they just a little better then the other models O2's

 

they are really wideband, to help the vx motor do extremely well with gas(running really lean is my guess). i was happy when i found that out, ordered the techedge and pulled it from my old motor. VX motors arent useless.

 

i guess VX is wideband..
