Radar confirms what ScanGaugeII says, and I've analyzed many miles on the turnpike. It really is the Honda speedometer that's off (in my case, anyway).

Perhaps your 14" wheels (instead of the expected 13" wheels) have made up for the error in the speedometer at the expense of the odometer's accuracy? Of course, if your gauges were accurate before the transmission swap, something else is happening.

I read and tested further (and better) and created a new thread on this: http://ecomodder.com/forum/showthrea...ion-25435.html

Take a look. A question would be what tires you are using.

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.
