Re: running rich under boost

  The mixture control system goes open loop at WFO and mixture is
  controlled by the map in the EPROM based on inputs from various sensors
  but not the O2 sensor. An LED mixture display will no longer "bounce" and
  should display a "richer than normal" mixture at WFO, though not a full
  1VDC from my experience. I always wondered if open-loop mode was
  triggered by the WFO switch or by the boost level, guess it must be boost
  level triggered if you are seeing open-loop operation with the WFO switch
