type 9 speedo rotations
good evening,
i tried to measure the turns of my speedo cable today ready to replace it with an electronic sender.
I jacked the back of the car up and put it into neutral. Turning the wheels one rotation resulted in prop turning 3.62 times (which is my diff ratio)
and the cable turning exactly once.
this seems highly unlikely to me, the speedo cable rotates once for every one wheel rotation and I just happen to have the right diff to make this
happen?
am i missing something obvious?

sounds a happy coincidence to me. isn't the 3.62 diff like the middle one out the sierra range?
maybe its like that to make calibrating sierra speedos easier?

I'm want to know the answer to this one (you a fair bit ahead of me)
all I know is that there are at least 3 different drive gears with 24 , 23 or 22 teeth (I assume thats how for calibrate for the range of diffs)

yes i believe so.
My smiths speedo requires two pieces of information, pulses from the sender per rotation of the wheel and the distance covered by the wheel in one
rotation.
Check your manual as this is probably the same with the KOSO.

got no expericnce in the koso speedo, but basically, the sensor puts out a signal, and you set up the speedo to give the correct speed reading for a
the output.
