Mark, I understood to whom you were responding to.  I merely
corrected your previous statement.  I'm confident with a lot of 
WB software, your statement will hold true however.

:confused:  Well, sure.  Why else would I post it?  :)  On numerous
vehicles/OEM PCMs, both foreign and domestic.  To avoid CEL on 
some (domestic) vehicles it is necessary to simulate O2 heater
circuit with resisters however.

 Yes!  That is what precisely has been done, richer or leaner.  Details 
can be found (with search feature) on forum section of link provided.

  I was responding to Darrell <ndarrell at telusplanet.net> when he said...

  "Cowen: (and all)

  Well, you are right, second times the charm.  Thank you for 
  responding anyway, and getting a little action going on the thread.  
  A lot of this information will be useful, thanks to all who posted on 
  the topic.  Some of it went way over my head, but I'm here to learn.

  Interesting idea about using a WBO2 sensor, has anyone actually tried 
  this?  I mean replacing a stock NB with a WB on a stock computer?  
  That in combination with changing the voltage threshold may allow you 
  to set the AFR to a slightly leaner mixture overall."
