<all> home dyno kit??

[Mike Pitts]

Seems like if you had a fast (8192 baud) home brew scan tool, 
you could measure RPM and MPH and make the same calculations, 
probably a bit more precisely since you would have MPH as an 
input rather than a calculation.

Anyone know the math for this off-hand?  Might as well add it 
to my cutom scan software (for 16198625 PCM's only, sorry).

Cool idea though.  Very creative with the inductive coil into 
the microphone jack.
