I thought for sure that someone posted the voltage graphs for both the wideband and narrowband O2 sensors here before, but I can't find them. Does anyone have that link, or have the graphs / tables that I can reference?

Thanks!

I think Russ has the NB sensor graph.

But the widebands can vary by different manufacturers. Most are linear from 0-5V.

Thanks! That's perfect!
Right now I'm using the stock O2. I have pulled the LED board off an old Dawes device, and added it to the instrument panel. I'm tweaking it so that it will err on the rich side. Eventually I want to use the same 4 LED's with a wideband O2 for better monitoring, and possibly to trigger a relay that will activate a wastegate solenoid if the AF gets lean beyond what I feel comfortable with.
