I recently changed sprockets on my 07 FLHX, I changed from stock 32/66 to 30/68. I need to recalibrate my speedometer. I know I have to raise the value in the speedometer calibration in Winn/PV. Would anyone know how much I raise the value and how I do it in Winn/PV.

 

How much depends on what sprocket you went with and how far off it was before.

 

2265 if the current setting is 2078. If not just add 187 to your current number. If your speedo is already off 2 mph fast as most are then add 58. You can check it with gps and for each mph fast add 29 points. These may not be exact, but speedos vary in accuracy from low speed to high speed also. I choose to get it right around 60 in 6th.

 

Thanks for the info, I think I did it right. I went into Winn/PV brought up my tune my current setting was 2058 so I added 187 to that and made it 2245. I saved changes then uploaded tune onto Power Vision. Now I need to hook up to bike and flash with updated tune. Is that correct or did I make a mistake?

 

that is the correct procedure. When it asked to reset learned just tell it no, since you haven't changed any of the fuel mixtures or timing. Be sure it is calibrated right before pushing the speed limit. My stock 10 limited was off 2.5 mph fast. After resetting and adjusting for the 2.5 it was dead on with 2 different GPS's.

 

Thanks I appreciate the info, I'm slowly learning how to use the Power Vision.

 

2245 is what I set mine at when I changed to the 30T on my '10 Limited. 2245-30T/68=dead on perfect.

2010 Limited with some stuff!!

the Bike speedometer unless you have changed it in the PV is likely off. check it with GPS as the PV is still a calculated number.
