Interesting!
My ride has a close-ratio, 5-speed tranny (S4C) with 4.4:1 final gearing.
I typically cruise @ 3000-4500 RPM (55-75 MPH).
Engine-on-coasting is 1100ish RPM, regardless of speed, 1-150 MPH...
As soon as the speedo hits '0' MPH, the idle falls to 900ish RPM too. Weird!
I *assume* this is due to some vagary in the ECU programming...
The ECU ultimately controls the idle speed in my car... probably yours too!
