I am wondering if anyone out there has ever analyzed the signal that
drives the electronic speedometer/odometer (the late coupe and various
type 44's are probably similar).
I have two busted odometers, and want to try to fix one "on the bench",
which would mean needing to synthesize the data stream from the sender
in order to see if I've succeeded.
So, anyone know... frequency to speed ratio; nature of signal - square
wave, sine wave, duty cycle if assymetrical, etc.?
