is it possible to hookup a wideband O2 sensor to an autometer air/fuel guage, and it be accurate?

if not, then is there someone that makes a wideband O2 that has a display that i can mount somewhere in the cockpit so that it can be read, and doesn't look out of place?

 

1) no

2) fjo, or the diy wideband with the impossible-to-get sensors

 

first you need something that will read the sensor signal (like the techedge unit). Then you can hook up a lcd read out and hook it up to the output of that unit

BTW ebay sells the lcd read out and they can mount it on a 2 1/16" pod for you, but really it's only a 0-5voltmeter

 

I have two new ones for sale in the classifieds

 

what about my seconday O2 in my Prelude, when i get my Hondata, i will eliminate the 2nd O2, so can i just wire a guage into it

 

The secondary O2 sensor is just another on/off stock sensor.

 

the techedge diy wideband output is not linear. You need the display they offer along with the unit.

 

sorry i was just going by their (the seller on ebay) description

sorry if i confused anyone

 

oooooooookkkkkaaaay. then where can i get a wideband O2 and a readout that i can mount in a 2 1/16 pod?

 

ttt

 

you'll have to fabricate this part as far as i know. i guess if you get the techedge display you could rig it up so that the LEDs are separate from the circuit boards.

 

ok, so, what if i buy an autometer guage and wire it to the O2 sensor just to make sure it doesn't lean out when i am driving, but when i tune it, i just use a wideband, then remove it when i'm done? i am having a shop tune it, so they have one..... would this be OK?

yes, i know, i sound like a complet n00b, i'm just wanting to be sure everything is right the first time.

 

not sure...but you gave me an idea...you *could* take the output of the techedge unit ( 1v - 4v) and by using a simple opamp circuit scale it so that you could feed it into an autometer gauge (0v - 1v). but, since its nonlinear like dustin said, you could calibrate it to be accurate at 1 particular point and then you'd either see if you're rich or lean if it was left / right of that point...but thats a lotta work just for some pretty lights...hmmm...

edit - plus you'd have to invert the voltage since 4v is lean on the wideband and 0v is lean on the narrowband. too much work - for me anyway
