thanks cbaber.
I don't have a factory service manual or scangage to show me the lovely 9999mpg.
I already understand what you are saying about dcfo vs eoc. I love eoc to the point of replacing gearbox oil in my last car with 0-20 synthetic and running 55 psi in the tires for really long coasts.
But, what I like about dcfo is the lack of effort/simpleness of it. Ease off the petal and fuel injectors are off! No key off needed, no kill switch to add, no bump start, etc. My non-eco passengers don't even know I'm doing it.

Just trying to find the rules my cars ecm uses to be in fuel cut off to understand it better, to be sure of when I'm coasting with injectors off.
