Umm, I'm guessing (I know, who asked me? :) what he meant was that most of the
better commercial UEGO equipment like Horiba's, ECM's, Bosch's, et al usually
offer a linearized (again I assume that's what he meant by 'normalized') analog
output of 0-5V.

But yeah, a UEGO sensor and a WBO2 *sensor* are usually considered synonymous.
He seems to however have been referring to the whole instrument, not just the
sensor. There was a time when the Bosch LSM-11s were referred to as 'wide-band'
in contradistinction to either the ordinary 'narrow band' or the newer 'UEGO's,
but that usage seems to be dying out with time; plus obviously the post wasn't
about that either. :)
