Gauge question
Is there any real difference between a wideband o2 sensor and just a regular air/fuel ratio guage. I know the wideband comes with its on O2 sensor, but i didnt know if there was a difference?

Accuracy!!, pretty simple as that i believe, and narrowbands are not able to work the the TC anyway....From what i understand TC's need a wideband unless you want to try to hook up the narrowband to have no reading?

The signal wire that usually would connect to the ECU or the primary 02 sensor to get the narrowband reading does not work on the TC as far as i know and if you would try to hook it up to the 02 sensor it would just sit reading either on one side of the gauge i would assume either all the way rich or all the way lean?

Dont know the exact answer on why it doesnt work, but it just doesnt i believe and you need a wideband?
IS your application on your Tc FI? why are you looking for a wideband? If your NA i would suggest a different moinotring tool for A/F then a wideband cuz i think you would be wasting your money on an NA application with a wideband.....There are multiple hook ups that will display mph, mpg, etc. etc. as well as A/F ratios. Might not be as exact as a Wideband But depending on your situation it might be all you want or need

here since i didnt help to much with the simple answers of no it cant work and its more accurate.....
One is narrow band, one is a wide band. What’s the “band” you ask? The band is actually in reference to voltage. A narrow band operates with a sensor in your exhaust, and it sends out a signal varying from 0-1 Volt. Narrowbands do not come with an o2 sensor because the rely on your stock narrow band (your primary o2 sensor) to give the signal. Some cars aren’t fortune enough to have a narrow band, so we use a wide band. A wide band is actually MUCH better to have than a narrow. Widebands, though more expensive, are MUCH more accurate in A/F readings. What makes them wide is the 0-5 volt reading the sensor samples with.

here is the source, might find some more helpful information about the FI world on there too....

you need to read up on how widebands and narrow bands work first and then you will understand why you need a wideband. Basically forced injection cars run alot richer than na cars... its something like 11-11.5 afr vs. 14.7 for na. A narrow band does not work very well, accuracy is terrible, the richer you get. So a narrow band is pointless for monitoring your a/f especially in a forced induction car.
