Adjust odometer/spedometer?

Is there any way to adjust the odometer or spedometer in an NB Miata?



In my 2003 the odometer reads about 2.8% high, and the speedometer reads about 7% high (with the OEM tires/wheels).



I think I'll put on slightly oversized snow tires this year. That'll get me a little more ground clearance and a slightly more accurate speedometer, but it would be nice if the odometer and the speedometer were a little closer to being right to start with.


Are the speedometer and odometer on a 1999-2005 Miata mechanical or electronic?

Yes.

Sorry, couldn't resist, should have tried harder.

The odo display is digitial (LCD), the speedo display is mechanical. I don't know what the underlying stuff is (spinning cable or opto-electronics).

I'll check mine if I remember (which is pretty unlikely, but I'll try....)

I checked my parent's car a couple weeks ago, and it's speedo was accurate to within 1mph all the way up to freeway speeds. I'm a bit disappointed in Mazda's engineers for doing such sloppy work.

My '96 seems to read about 5mph high thru 50-75 range.

Yea, but because of the current limiting, it's going to require a computer with 30,000 USB ports to get 100HP worth of electrons.

Well, yeah, but there's a turbo kit....

Mine's "titanium", so I don't get much reduction in photon-induced drag when compared to a standard black-body.
