Nice work with the skirts, hey!

Yes, shift down to keep RPMs above 1600. You may even be able to feel when the car turns off the fuel injectors a second or two after you begin to coast in gear with a warmed-up engine you might feel a slight shudder or hesitation for an instant. That's it happening. But you don't always feel it.

As for battery, it depends on a few variables, such as day or night, music or now music, lots of stops where I have to key on. But in ideal conditions I can go the 25 miles round trip to work without using the alternator at all. Usually, I start using the alternator on DFCO as soon as the engine is warmed up.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. 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.
