This is all very foreign to me. I have a motorcycle with a carb on it. So I'm not understanding how engine braking can give you better fe than coasting in neutral. Maybe it's just me, but I've coasted a lot using engine braking (before I knew what ecodriving was) and a lot just in neutral, and just by listening to the sound of the engine you can notice a huge difference in RPMs when engine braking. Is this something on newer cars? I had a '07 Dodge Caliber and it seemed about the same results. If fuel is usually cut off from the engine during engine braking, how does it continue to run?
