What should my A/F ratio be on a wideband?

What should my A/F ratio be on a wideband? Maybe a dumb question but I have an Autometer Ultra-Lite Wideband O2 sensor and gauge in my car and I don't think it has ever worked correctly. It ALWAYS reads between 14.7-15.0, never have I seen it below or above that. So my question is what should my A/F ratio be according to the wideband? Like I said I have never seen the gauge show anything but that whether it be at WOT or pulling timing for nitrous or anything. Also mods are in my sig and it has been tuned by Ion.

Thats just it though, the A/F never changes between 14.7-15.0 whether I'm WOT or just normal driving. I've asked Autometer tech guys and they told me to unplug it.....ummm yeah don't you think I've tried thaty multiple times already! LOL

where did you mount the WB sensor. On startup does it goes through a warm up stage then count down from 15 IIRC. Then should show round 12.5-13.5 while warming up and going into open loop.

It is mounted right after the header collector in my Y-pipe. And yes it does do the whole countdown but no matter whether it is a cold start, hot start, WOT, or just regular street driving, it always reads between 14.7-15.0. The guy at Autometer also said it could be because it is picking up interference from somewhere and to run the wire somewhere else. I'm talking about the wire from the O2 to the gauge. I have already tried different grounds and powers.
