Purion speedo needs calibrating?

[tobster]

I've just got my 2019 powerfly LT9.7 back after a motor change and have noticed that the speed read out from the Purion display is slightly optimistic compared with my garmin edge. I tend to believe the Edge. Is it possible to calibrate the Purion say by entering the actual rolling diameter of the drive wheel?

On the Purion it's not possible for you to do, but your dealer can make small adjustments. It's kind of a bottomless pit to chase this though. And your Garmin is also not totally accurate. It's understandable you want them to match of course. But...don't expect to get it perfect.

As I can't tweak it i will sleep well tonight. There are more important things to worry about....
