Are you sure the CRV doesn't have DFCO? My 1996 civic does.
I also say that unless it's in Neutral, it's not a glide. I doubt you'll see much gain from pulse-and-DFCO. Neutral is where the gains are. If you can get the transmission to unlock, you're most of the way there without shifting to N. You might try a tiny blip of the throttle right before letting off, to encourage it to unlock. The rpm should drop to near idle level.
