cable to electronic speedo sender
the instructions for my electronic speedo ask me to calculate a few things to allow calibration.
My new sender gives 8 pulse per cable rotation. To find the number of cable rotations it tells me to roll the car on flat ground for 6 full rotations
of the rear wheels while watching the cable spin round.
I dont have the space to do this, is it possible to just hike the back end up and manually turn both wheels?

yep, but you have to be sure they both turn the exact same amount (so you don't lose any rotation in the diff) otherwise your calculations will
be out
although there was a similar question last week i think, about working out the diff ratio. if you lift 1 wheel off the ground, and turn it 12 times, i
*think* that should give the same answer, but don't quote me on that lol

its an lsd if that makes any difference?
i was planning on getting my brother involved to turn the other wheel at the same time... possibly mark both of the wheels to ensure they're
going around at the same rate?

lol no, i know, just got me thinking, if anyone had a type 9 laying about and could check if its 1:1 (prop vs cable) then you could work the rest out
with maths
