All of the sensors mentioned, and anything else in the price range in
question is little more than a narrow band switch, that switches on and off
at stoich. They are little better than useless for determining anything but
whether an engine is running above or below stoich a/f ratio. They are
virtually complete POS's for doing any serious tuning more than 0.5 ratio
away from stoich.

WBO2 (Wide Band O2) sensor meters are a totally different kind of beast,
and far more useful for serious tuning work. 'Til now have been ludicrously
expensive (and also overpriced). The Greddy unit MAY be the first such unit
on the market for a fair price.  Such WBO2 (or UEGO) sensors  (as opposed
to EGO or HEGO) only came OEM on things like Porsche 930 turbos and Honda
VTEC's, and now maybe a Toyota of some description.

Try a word search in the srchives under <EGOR> for the full story.
