On most Hondas the cutoff is at 1100 or 1200 rpm. Above that you get fuel cut.

Watch a scangauge for the Open Loop condition. That means the computer is not watching the exhaust O2 sensor reading. There's no need to, and no need to adjust the fuel flow, if there is no fuel going in to start with.

It's not scientific, but I never use DFCO in my hypermiling. I get good results from that, among other techniques. (and I don't have to guess whether the gauge is handling it correctly)
