When coming down hill and down shifting if I don't feel computer has cut fuel or note that it is still in closed loop I can blip the throttle and it will go open loop and zero fuel consumption immediately. The "blip" is not even enough to feel, just enough for the computer to see a change in throttle position.
I will have to check for this in the escort.

IF DFCO means that the ECO cuts the fuel on decelerate, then I got it. My "The Beast" RV will cut the fuel mostly anything over 50 mph. The MPGuino shows 999 mpg. Lower than that it shows 60-30 mpg as it slows down. 454 Chevy w/ 4 speed automatic tranny.
I LOVE to coast!
16 mpg, best so far.
