These are really interesting results. And thanks very much for them. I really appreciate the commentary on the way the GPS works. And I'd also love to have more d-series Civics test this stuff. Your last comments also raise some things I'm still curious about. (1) Do we know what the stock tire was and what its rated revs/mile was? I at least don't, and if I read the tirerack.com listings I see significantly varying revs/mile ratings for different tires in the same size category. And (2) in my experience the speedometer error tends to be higher than actual while the ODO is lower than actual. You cannot get the ODO and the speedometer to both read accurately at the same time. At least I can't. That suggests Honda designed the system to report "erroneously" for some reason, no?
Vexing.
