Still, good testing, thanks for doing it!

It would be interesting to see what load the engine is at at those rpm ranges.
So this means that with a CVT if you throttle it higher, the engine will first increase load at a relatively steady slowly increasing RPM and then depending on power demand indicated by throttle position, increase RPM by shifting gears if necessary? If that's true we really do need a guaged "engine load" reading rather than the butt dyno, no? Maybe a throttle position reading too?

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.
