Great. The trick with the cabin air recirculation selected but without running the fan was the biggest surprise. I expect it'll work for you too. I also found that I could set the heat level in the middle between hot/cold and get a predictably more modest effect. I like the idea of keeping coolant temps in the low and mid 190s.
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.
