I love your interpretation of the Gen 1 Insight map. I totally agree about the heritage thing. The 2000 Insight was launched in the last year of the 6th Gen Civic (96-00), and lots of engine and trnasmission features were similar. You can see it really clearly in the FSMs. But I can't agree about your RPM recommendation. Why so high? In my experience (and PaleMelanesian's) ... it would suggest, as this map does, that 1500 to 2200 RPMs is the best range. And we drove it at 75% load. 3000+ rpms seems like screaming it.

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.
