The Busa is made with either mph or kmph gauges, depending upon which country it's being sold in.
I do not know the internal differences.
There is also no way to program one to the other with just the dash buttons.
You need to talk to Scott at Blue gauges. His company changes led colors, guage faces, does repairs, as well as resetting, changing, and correcting odometers. If your gauges can be converted, he can do it.
Of course you have to mail your gauges to him.
