etb speedo setup

[baz-r]

it would purley depend on how you have your pickup set and tyre size.
if you had a pickup fitted say to a drive shaft that had 1 magnet then it would be the amount of revs a tyre will do in one mile.
if you had a magnet fitted to your prop and a diff ratio of 3.6 you would multiply the above revs by 3.6 and if we use a gear box cable drive adaptor we could have even more maths to work out as we need to check drive ratios of the cable drive and so on
all we are realy intersted in the amount of triggers we have in a mile
it will be diffrent for everyone as it will be affected on placment of pickup tyre size diff ratios gearbox cable drive ratios etc
