Re: O2 sensor readout (Air/Fuel ratio indicator)

   lower limit (around 0.1V).  If you are trying to get accurate air/fuel 
   ratio information I don't think the O2 sensor is capable of giving you 
   the actual degree of richness or leaness you have.

But what it can tell you quickly-enough-to-avoid-engine-de$truction is that
(e.g.) at full-throttle full-boost full-rpm your fuel system is maxed-out
and can't deliver enough fuel, resulting in a *LEAN* mixture that in about
129.7ms will either detonate your head into shrapnel and/or melt it into
shot, if you don't back off RIGHT NOW. (Note: this would probably only be
a problem for those miscreants who have slipped in a hot cam, upped the
boost level, diddled the computer/timing, etc.)
