Kinda interesting that you mention calibrating to a voltage.  On the display
it indicates a AFR.  How do you calibrate the unit refence to a AFR?.
  Point is conventional O2 sensors are effected by EGT.  So they must have a
correction to that or the read out is subject to huge errors, ie .83v can be
anything from 11.3 to 12.8...
  To read about EGOR means reading the related materials
