I was just wondering, it is possible to change the odometer and trip counter from miles to kilometers, or is that in the cars computer?

i would think it's in the car's computer...i wouldn't think it's possible to change it, but i might be wrong...

that is the computer and gauge cluster too.

It's possible. Dealers do it all the time when they get Canadian cars. I dunno exactly how it works, though.

Cluster is easy, just a swap but the computer is needed for the miles to KM conversion
