the fuel doesnt shutoff when you downshift, but it will save your brake pads in the long run. with the current gas prices i just coast in neutral, saving my gas, but using more brakes

actually, the cars computer is watching the fuel use most of the time the vehicle is running, aside from wide open throttle.
in essence the computer is only supplying sufficient fuel to maintain engine speed. even on deceleration, the cpu, sees the signal from the throttle, and adjusts fuel output accordingly based on TPS, O2 and a few other sensors.
some manufacturers do in fact shut off fuel injectors in some situations, but i have not heard of honda doing so.
Cadillac does shut off injector activity to oscillating banks in an overheat situation, and i believe Dodge is doing something similar in cruise mode ,roughly turning a v8 into a 6 or a 4 cylinder. Once you are up to speed, why fire on all eight if you can get enough power from four to maintain speed.

Any vehicle, ANY vehicle, uses fuel while the engine is ON. There is no way around this. As for using LESS fuel during deceleration; I suppose so. The injectors will stop pumping as much fuel to the cylinders during deceleration, providing just enough to keep the engine running at idle RPM.

You just coast. Like the guy said above learn to coast and save gas and wear and tear on the brakes. Coast in neutral
