OMG, I just noticed that I deprived everyone of 5 or 6K of warranty. As far as I'm concerned, everyone should get three years or 37K miles to compensate for the over-rated speedo/odometer. Until then, remember you're not going as fast as you think, your mileage is not quite as good as you think and your not getting the mileage warranty that you paid purchased.

Good point.

The reason I get a little anal about this whole thing is because I got a 67 in a 55 ticket a number of years ago in a Chevy Caprice. I thought I was going 62. I mentioned it to the cop he said to check the speedo because he had seen slow readings in that car before. Still got the ticket of course. But he was right. I remember holding it at 60 and seeing the mile markers click off at around 54-55 sec. Never thought to go back to Chevy.

Guys, this is perfectly normal in all our cars. It is common for our cars to run about 1% higher on the dial than it actually is going (on stock setup). This has been discussed several times on the board. There have also been products available from the marketplace here on S2ki that fix this. One is the yellow box and another is from Modifry and is called the yellow jacket. Both address the same issues. Check out the marketplace for these.

I mentioned the speedo deal to the svc mgr at Acura dealer. He said they couldn't adjust the speedo. Because of the odo tampering laws I think they just don't want to get involved.
I assume the yellow box approach somehow modifies the signal from the drivetrain sensor?
Someone suggested trying to beat one of these tickets by bringing a statement from the dealer. That's a pretty good idea.
In my situation I got the ticket way out in the country and out of state. The cop said I could go into town and post bond or I could pay on the spot. I asked if he took credit cards. He said yes, pulled out an imprinter and I was soon on my way.

I had a similar finding for my 05 S2K. The speedo reads between one and two MPH faster than my Garman Quest GPS. I have found that every stock car that I've ever tested has a speedo that reads faster than the actual velocity. I think that this protects auto manfacturers from liability. E.G.; "Ladys and gentlemen of the jury, the sign for the curve read MAXIMUM SPEED 65 MPH and my clients speedometer indicated 65 MPH. How was he to know that Honda had under-rated his speedometer at the factory and he was actually exceeding the maximum speed for the turn. Honda was responsible for this accident and should be held liable for the tragedy ... ." 
Sorry to be so cynical, but it is safer for car manufacturers to make speedometers read a little fast so they protect themselves from liability of ever having one read slow.
How about this approach ... When I purchased my new Honda, I purchased a 30K warranty. By over-rating the speedometer, Honda over-rated the odometer and has denied warranty coverage to me and hundreds of thousands of other Honda owners that represent millions of miles. We deserve compensation ... maybe a free hardtop or warranty coverage to 31K on the invalid odometer. Let's get some clever lawyers working that angle right away.

On the second paragraph, just because the "speedometer" is optimistic, doesn't automatically mean that the "odometer" is optimistic. As near as I can tell, my odometer is pretty close. Certainly not as far off as the speedometer is.
FWIW!
Drive Safe,
