If you get a Scangauage (which will display your instant mpg), you will observe a big difference in coasting techniques. Sometimes when the car is coasting under the right conditions, the instant mpg reading will jump from 100-200mpg to 9999mpg. I think under the right conditions, the computer can almost shut off the injectors completely when the car is coasting.
