An injector shutoff does sound like an interesting idea. Maybe even tie it in with an alternator kill switch; injectors turn off and alternators turn on while coasting downhill, injectors back on and alternator off when the engine needs to go again.

I know DFCO was used on the 1981 Nissan 280Z, possibly even the 1975 model, the first year they were injected. If your car is fuel injected just place a screwdriver tip on one of the injectors with the plastic handle in your ear, making it a crude stethoscope. Rev the engine and listen to the injector. If it stops clicking completely when you let off the throttle, it has DFCO.
