Power Vision Speedo Re-calibration
hd brain
I know this an old thread but still relevant.
Trying to calibrate my speedo/odo
PV and speedo/odo are off, and I dont think they should be, they use the same data.
Speed is off by 0.61%
But odo is off by 0.78%
On a recent ride my PV trip center mileage did not match the odo mileage.
Am I missing something? I am using the quick tune to change the vss parameters
Thanks

It will require a second license. The Power Vision is married to the first vehicle it is used on.

You can also do it just from the PV. Goto Quick Tune, once there goto the config tab. You will see a box marked VSS. Make note of that number and make and save your changes. Remember if you reflash from the stores tunes and you did not modify it in the tune it will over right that number

There was a thread a few months ago with the guys who have FP3's and theirs will auto adjust based on the GPS in their phones. From what they were saying somewhere between 2235 - 2245 pulses is correct for a stock bagger with a 180 rear tire. Mines set at 2233 and I think that came from a map I got from Fuel Moto.

You don't have to use the pc to do it. You can change the vss directly from the power vision. It's I the quick tune section. Very easy to do.
Sorry didn't read the whole thread.

On a Rushmore model with the GPS, is the speed displayed on the screen linked to the vehicle speed sensor, or is it actual GPS speed? My screen and speedometer are slightly off. I use the number on the screen more often, and it is accurate, but I will adjust the speedometer with the Power Vision if they aren't linked...

If you have PV you can change the PV speedometer calibration about 100 points more and the speedometer should read about 3 mph faster. Then compare and see if different.
