hi all, second posting as no one has replied to other one. i have been attepting to setup my koso speedo. has anyone got any idea how to set it up. my sensor and 4 magnets are on the prop, im running 195/50/15s and i think it may be running a 4.3:1 diff ratio.
any help is greatly appreciated as sva is on tuesday and am bricking myself.
thanks

rob

I could be wrong but when I read my Koso manual ( along time ago !). you have to tell it how far yo travel between each magnet pulse .

So I would

1/ mark the ground and tyer with a piece of chalk

2/roll the car round one rev of the wheel and mak the ground again

3/ measure between the two marks on the ground

4/ divide the measurement by the number of magnets ( divide by four in your case ) and this will give you the number to input into the koso unit .

You dont have to worrie about diff ratios and tyers sizes as the the drive shaft turns a fixed amount of times per rev of the wheel .


Hope this helps

Please let me know if it works for you .

Cheers

Vorn

Just to add to this - you don't divide by the number of magnets - the koso has a seperate setting for how many magnets you are using I believe....

not the prop
koso has to go on something with circumference of 300mm or over......
if not forget accuracy.

i had this confirmed direct with them.....
