Idle adjustment quandry



The Bentley so-called manual makes me crazy. I would simply
like to adjust the idle speed screw properly.  Should be a simple
matter.  The IS system is a closed loop affair and one would
expect to be able to set the ISV duty cycle or current or
something with the speed screw.  Probst's Bosch FI book
says as much.  But Spentley?  If this info is in there, I'll be
damned if I can find it.

Phil mentioned an ISV current of about 430 mA.  This is
right at the actuation threshold of the valve - per 2 samples
measured - on the bench.  Is this the ticket and is it in the
5000 manual somewhere?
