There is no question that an 09 Fit has DFCO. My 1998 Civic has it. And so did much older Hondas, I am told. Honda was somewhat early in applying this technology widely in its car, it seems. Suspect the torque app and the scangauge... they might have settings that need adjustment. My ultragauge had to be set to recognize dfco. If your engine is warm, in gear, and rpms are over 1100 you'll go into dfco within one to 3 seconds as soon as you take your foot off the throttle. Sometimes you can feel it, since the car will often shudder slightly when fuel gets cut.

My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
