I see. thanks for the clarification.

I thought that I saw somewhere in Bentley, but not in the section you expected to
find it, that the idle stabilizer control that connects to the Hall sensor
actually sends trigger pulses to suppliment/replace the ones generated by the Hall
sensor/ But I can't find it now, so perhaps I was having a hallucination.

Sorry for mixing up the years.
