You have it backwards. When the car first starts it is in open loop ignoring
the O2 sensor. Once in closed loop the O2 sensor is used to control mixture
and prevent pollution. Bad O2 sensor will burn out the Catalytic converter
because of too much fuel in exhaust.

My reading of his post suggests it's a "monitor only" O2 sensor. With the
data from the O2 sensor, the pilot then controls the mixture manually.

I understood that to be the case also.

My point is that in auto systems, the oxy sensor information must not be
very valuable, since the computer ignores it at high power, which is where
this system is attempting to function.

Would the sensor/monitor have very much positive benefit, is my question.
