the rabbit diesel does not cut fuel off on decel much to my amazment. it goes to idle fuel. so i put a button on the shift lever to cut power to the injection pump. during decel in a lower gear, i can actually feel it slow down when i hit the button. but for max mileage it is far better in neutral. because i coast three times as far.
My gasoline truck does cut fuel over a certain RPM, but it take too long for it to cut and it comes back on way too early. so neutral is far better there also.

Next i am going to cut the VSS signal during neutral coast on my windstar because ECU tracks the vehicle speed with the engine even in neutral, dumb computer.
