Stage 6 mkii display question: How many magnets did you use? I cant seem to make it read accurately,it always read low vs gps. Followed proper units,measurements, placement and minimum distance from magnet(3pcs) to sensor. Am i missing something?

Almost all speedometers are able to be calibrated. I tinkered with mine as far as mm of rolling distance per magnet input to make it match GPS. What distance are you inputting? I think I’m up around 1400mm on a 120/60-12 tire

But now that I’m thinking about it more that seems high. I’ll go back through my build thread (‘08 Keeway F-act) and see what I used.

Mine had the right amount of magnets and spacing but one of them had reversed one (north south) Made them all face the right way and that fixed mine.

I have not used a Stage 6 display, but have much time with Koyo and Trail Tech units. (The Stage 6 might actually be a Trail Tech, not sure) Your question regarding how many magnets is confusing to me. My answer would be only one! Both Trail Tech and Koyo use only one, but I recall a spare in some kits. The other installation tip is that the magnet should not be centered on the pick up. I usually get good results by having it near the bottom, away from the lead wire. As stated above the magnet orientation needs to be correct. They are/should be marked. +/- or newer Koyos are P/N on each end of the magnet. Here is Trail Tech's install guide: (ignore the Polaris/KTM/whatever references) cdn1.polaris.com/globalassets/trail-tech/2020/home/pdf/010-elv-199.pdf?v=834b67d1Having three magnets, IMO, could cause many issues. If that is what the install guide says, I wonder what do they (Stg 6) think would happen if one goes bad? Or even new...one or more could be weaker than the others. Kind of strange to me. Do let us know what you find! |

Did you actually measure round the centre of the tyre? If you have, and put in number of sensor points. It shouldn't be far out.
How far out is it? Perhaps just keep reducing the tyre circumstance till it matches the GPS.

I think there are many clues in the Trail Tech/Koyo/Stage 6 tech install PDF's. The biggest issue I have experienced, was an install on a road bike with a worn front tire...old and worn. At 100+ mph (indicated) is was both scary and reading way too low. I was on a parallel path, next to my brother...reading 115+. Mine reading low, I think.
That was an old bias ply tire/tyre that grew/expanded a huge amount at high speeds. More circumference makes the digital world go nutz. If you program in a 940mm/37 in. circumference, (rough guess for a 12" tire) and it either deflates or expands then it will be different. Digital is not always kind with analogue conditions. All speedo's go off the original calibration, due to that expansion, tire wear and even ambient temperatures.
I am sure you will find a good answer. Murphy's law says so.
