    gear and tire calculation 2.25 beta

    Since I downloaded 2.25 beta I see there is no longer a parameter for entering gear and tire size. Is there something I'm missing or do the math manually.

    i have always had to do it manually. the calculator was always off, mostly due to differences in tire manufacturers. just remember that the numbers are opposite, meaning when you increase the number your speedo will slow down. the real trick is getting the scanner mph and speedo mph to match gps mph. there is a decent writeup on here somewhere that explains which numbers to adjust and how to calculate the starting points.

    It doesn't have to be perfect, it just needs to be done in two weeks...
