Changing The Navigation Coefficient
I've seen some other threads on how to change the wheel coefficient in the navigation system so that the vehicle's travel is tracked more accurately, but is there a way to change this coefficient on vehicles that do not have a nav. system? It sure would be nice to be able to change wheel/tire sizes to something smaller/larger than factory and still have accurate speedo readings, no?

Depending on the final wheel & tire diameter/circumference after upgrading, the difference may be significant. Sure, the speedo isn't going to read 80 when you're driving 60, or something else as absurd as that. I guess it's just the principle of the thing: You've got this expensive luxury car and you've spent even more $ customizing it. Yet the simplest thing, like the speedometer, doesn't work correcty.
It's disheartening to think that after upgrading my wheels & tires that a $15 Timex watch would be more accurate than my speedo...
Anyway, back to the original question: Does anyone know if there is a wheel coefficient setting for non-Nav vehicles?
=========
Manaray: Perhaps your new wheel/tire combination has a coefficient that is very close to the original wheels/tires. Tell me the factory wheel/tire size and what you have now, and I can determine what the new coefficient is.

Just a question....
wouldn't it just be easier to get the wheel/tire combo that is exactly the same OVERALL diameter as stock? That way, unless you are going to 21, you won't change a thing.
Let us know what your plans are

I remember a friend with a 240SX kept getting speeding tickets all of a sudden....found out why. He had just gotten a "deal" on a set of tires...but they were way oversized compared to stock. So when we did the calculations, he was 17% off of stock!!!! So when he thought he was going 65mph, he was actually going 76mph.
