Didn't realize one should recommission a motor after 600 miles ... will have to check mine
Will likely have to wait till next weekend though as I got other things to do ... by then I will likely have 2.5k miles on the bike :/
The offset is the angle of the sensor. I have a video out there somewhere on how to commission a motor but basically you are adjusting the encoder so it can read the motor RPM properly. If the offset isn't set correctly all sorts of odd things can happen.
Yours wasn't too far off though. When you first get a motor from the factory they typically put the offset right on the side of the motor with a sticker to make it easier for installation but you still want to check it after installing it and simply use that number as a start
I thought the MY17's though had two encoders as I have seen two angles reported in the DVT software :/ (like the throttle having two sensors now instead of one though only one appears to be used at the controller on PIN 22, pin 23 is ignored so far as I can tell.)
