i have a programable speedometer in the car im working on it has a range of 500-900,000 ppm using the default 2002ppm it upadates a bit slow. the question i have is how high can the gpio go without loosing accuracy or saturating the output

ashford,

It depends entirely on the VSS input. This is covered here: http://www.msgpio.com/manuals/mshift/V41tune.html#sf

Lance.

vss input is roughtly 93000 ppm divide by 5 and get 18600, so the code should handle this well?

Yes, it should be fine.
