[Diy_efi] wide band O2's

Yes, the 'free air' reference from another post. 

Brian, with sensor 'drift' a normal characteristic of WB sensors,
(especially in performance environments), I question the solution 
to the problem, when free air test shows sensor drift, and analog 
circuitry unable to provide for manual (re)calibration.

  You have a point. There's always an easy way to check though just take 

  it out and let it sit then check what AFR it's reading.

  BTW, I was referring to digital processing, not necessarily the 

  display.  Another thing regarding the PLX; there is no 'in use' 

  manual calibrating.  It is my understanding, it relies strictly on 

  the sensor's calibration resistor.  Again, I question the accuracy, 

  especially after it has been in use for some (hours) time.
