ADX Editor equation for mph

[Eds]

Can someone tell how to calculate the correct equation in my ADX editor for mph? When monitoring or logging, my mph displayed is about 2/3 of that of my actual speed.

I will prolly get laughed at here but, a hack way to do it is to add whats missing. If the reading is off in a linear slope it's easy. Say at 65mph is shown in data and actual mph is 60, same at 55,45,35,25, etc, just add 5 to the existing equation. I don't have that mask to look at but just as an example.. (vsspulse / 255) + 5 = X. In either case you can play around with the current equation to see if you can manipulate it to show the correct mph.
