Hey All.
Just a quick update. I have not had a lot of time to play with wife's car - was in a conferance all last week in Upstate NY.

But i have managed to do a little with it. No SC info - only car's Tach.
@ startup (cold) the RPM hover above 1000 for a while then settle under 1K
@ startup (hot) the RPM touch above 1000 then quickly drop under 1k

driving at speed - Shift to N - the RPM do drop very slowly but will fall back to under 1K if long enough coast ( still at speed)
Neutral coast to a light - the RPM seems to drop faster then just a long N coast.

Conclusions - the engine does seem to be watching the transmissions RPM and keeping things close. As i noted before the engine does not have a Fuel Cut off - so for me it seems that coasting in N is the best way to go ( about the same MPG from SC - but longer coasts)

Thanks for the input - If / when i get the SG in her car - i can update with GPH info as well.

Steve
