Pulse and Glide question

[palemelanesian]

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.

I'm thinking P&DFCO might be more efficient as the engine ends up working closer to its peak effficiency, and then shuts off the fuel for a moment. Just a theory.

Well, as I mentioned above, I had the same theory but reality worked differently...but maybe the unlocked-TC hybrid DFCO-glide will work better.

Maybe to differentiate from manual transmission P&DFCO we could call it GFCO (Glide Fuel Cut Off) or TFCO (Torque converter Fuel Cut Off) or UTCGDFCOCARU (Unlocked Torque Converter Glide Deceleration Fuel Cut Off Crazy Acronym Recursive UTCGDFCOCARU).

Other possibilities:
DIGUT (DIGUT Isn't Glide, Unlocked Torque converter)
DIGNUT (DIGNUT Isn't Glide, Neutral Unlocked Torque converter)
TONGUE (Torque converter Open, Not Gliding--Undue Effort)

I like DIGNUT. Shall we add it to the glossary thread?

LOL, that was a joke...it would be an inaccurate term since "Neutral" isn't really involved.

I suppose DIGUT could be taken seriously, though.
