Ah, now I see what you're asking.

Your car already has a feature called Deceleration Fuel Cut Off (DFCO). I'm not exactly sure what your specific RPM threshold is for this state to be active, but it's likely your fuel is already off under those conditions.

Build yourself an MPGuino, and you'll know for sure!
