Motronic question

In the CIS systems, there is a basic CO adjustment that
insures the mixture control system is operating about
the center of its control range in closed loop. For example
some, maybe all, of us CISers can set this by monitoring
the duty cycle of a mixture control signal without resorting
to actual CO measurement.

The big question is do the Motronic systems of the
same late eighties era have an analogous situation
and means of monitoring the control loop without
CO measurement? Major Bosch guru points potential
