You fixed something.  This is what it's supposed to do - or at least,
it's what the ur-quattro ISV controller is supposed to do, and I think
it's the same part.

Idle is 800 rpm at rest - optimised for low vibration.  It's raised if
the battery voltage is low or the a/c is on.  The ISV will _not_ allow
idle to drop below 2000 rpm if the vehicle is moving - it assumes you
might need the power steering or the brake accumulator refreshing.

If you knock an ur-quattro MB (equivalent to the MC engine) out of gear
and coast gently to a stop, the idle drops in specific stages and
finally drops to 800 rpm some seconds after the car comes to a halt.

Not yet, but it will be fairly soon.  It's called a "tick".
