Hmmmm.... the electronics guy in me is jumping up and down at the idea 
of a device designed to calibrate itself to the likely inaccurate tach 
on the dashboard, when it probably has a more accurate clock inside to 
count against! 
Heck, you could then use it to check your tach's accuracy,  rather than 
the other way around..  but that's me..

Uh,  Alfa's rule!!!  (Alfa content)
