An observation/question or "am I missing something", not a complaint:
I added a VSS sensor to vehicle "B" in order to be MPGuino capable. Known is that in "direct" 1:1 transmission gear that ~2450 RPM = 60 MPH. Thus 1 minute = 1 mile = 2450 driveshaft rotations with a 4 toothed sensor wheel = 9800 teeth or pulses/mile.
However, it seems as though both a rising and falling edge are registering as a pulse since displayed MPH was double actual. PPM needed to be set to 19600 to display a realistic value (not yet calibrated -- just ballpark).
