O2 sensor band

[96spyderman]

I posted earlier about my A/F guage.... I talked to a supposed knowledgeable guage installer from autozone...
He told me the readings that my A/F guage are giving are wrong.
He said that the O2 sensor WE have is a wide band sending a wider band to the ECU as where the A/F guage is a narrow band reading instument...
He suggested that I get an O2 simulator for the 1st and 2nd O2 sensors and hook up a narrow band O2 sensor in the exhaust manifold/1st o2 bung dedicated to just the A/F guage...
That just sounds WRONG... if my car was running lets say LEAN and it thought it was fine wouldn't that be a problem because of the O2 sim?
The A/F guage was set up exact from VFAQ.com's instructions!!! What gives?

Whether the gauge reads right or wrong, you don't need to get anything to modify your o2 values. Only some people tune by o2, and they have expensive wideband o2 equipment. The same stuff that the dynos use. I wouldn't worry about it.

I'm trying to remember what the gauge reads, because I know Kevin had a modified gauge that was ultra narrow band to be more specific, but most gauges are practically worthless.
