Reviving a somewhat old thread: my speedometer is now almost exactly accurate, according to roadside radar readouts, but my odo is about 5% pessimistic, according to comparisons along specific routes plotted using GPS. The reason? Not totally sure, since the fifth generation CX transmission I just installed should have the same speedo gear as my sixth generation DX and since the VSS sensors are supposedly the same for both trannys. I am running 14" wheels with a no-name generic tires. Perhaps the speedo gear and VSS were designed with the fifth gen tranny in mind, with 13" wheels. And therefore, perhaps, all sixth gen, non-Si Civics actually under count distance quite significantly. Or perhaps Honda made a tire selection that closed the gap somewhat between the 175/70-R13s and the 185/65-R14s.

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.
