    TSDZ2: How to Set Odometer?

    Open-Source Firmware Version 20.1c-22 When I go to Settings/Various/Odometer and change the number, it jumps to 1,400-and-some miles when I exit "Change" mode. IIRC, I succeeded in changing the odometer value once in the past, but do not recall doing anything different. What might I be missing?

    Somewhere along the line, I got the idea that the TSDZ2 I recently ordered was good with 52 volts. But then I read that using a 52v battery constituses "Overvolting" and has the potential to cook the controller. Then sonebody said to flash the OSD firmware and all would be well. But that...
