intentionally reducing the odo reading is fraud man.i think i found the solution to my problem last night. i drained my battery down twice trying to get the right % plugged in
anyway, i should've used the calculation i got from the equation they they sent with the instructions instead of using the online calculator. after plugging the -15.8% i got from the equation i was less than 2 mph off at 70 mph. that's close enough for me. the gps was reading 68.4 mph when my speedo was at 70.
now i need to learn how to set the toggle switch i can create another setting that keeps the mileage very low while i'm riding. i've got the button mounted on my triple tree. this v4 is pretty cool once you get the hang of it
