narrow band or wide band ?

The only way to accurately check the A/F ratio is with a wide band 02 sensor and 14.7:1 is ideal.
 
Narrow band works from 0 to 1 volt and is only designed to keep an engine around 14.7 to 1 AFR at .45 volt with the ECM adding cross counts to swing back and forth.

Wide works from 0V and 5V for an AFR of 7.35 to 22.39 accurately, no cross counts.

What I bought years ago is:

But has no gauge, you can add one but I just use it hooked to laptop and data logging

What I should have got was:

still needs a gauge

Now there is a new one with wide band controller built in gauge:

narrow band: gives a visual indicator (in cab) of what the factory O2 sensor is reading.

wide band: gives a visual indicator of what an aftermarket wide band O2 sensor is reading. This is an analog setup.
 
BTW: I'm using this one from moates.com

doh, just saw this is the one Mark linked to also.
Well it won't replace the narrow band to ECM/PCM. The ECM/PCM just can't use it. Just that you can wire it into the AutoProm and add a channel to ADX (data) coming from ECM/PCM into so the readings are in same log.

Or there is a way to wire it into PCM and get it into data log to on some ECM/PCMs, but have to make soem changes in XDF/bin to work. There are instructions how to do this in 427 adx made by 98V8S10. which is same type PCM you have, it replaces the EGR pintle setting IIRC...
 

I think some of us were focused on the "Tuning" tool uses for an AFR gauge. I think if I were to use the AFR as a gauge, like using a tachometer, oil pressure gauge, or temperature gauge I would use the narrow band AFR gauge. I think the narrow band AFR gauge would be more likely to show the same readings similar to the actual narrow band O2 sensor used by the ECM.

This is very interesting to me. I would love to have wide band info synced to the data log. It could be exported and at least eyeballed to the blms at the same time line.

Not sure exactly how it would be done on your setup... gregs78cam at www.gearhead-efi would be the one to ask, he's an expert at making xdf paremeters for that kind of stuff.
