I've seen this on three LCD installs, Normally I ignore it, but I'd like to fix it. At slow speeds. up to about 12-14 mph, the speedometer is steady. ABove 16 mph, it starts flashing between 15 and 30 mph, and is unreadable under acceleration. When back in coasting mode, the speedometer settles down and reads the wheel sensor. The accumulated distance on the odometer appears accurate.
Thing is, I had a bafang fat bike motor with an internal speed sensor with no issues. When salt corroded the internal sensor, I had to install an external and the same behavior started.
One thing I need to try is set P2 = 0, which tells the controller to determine speed from the motor positioning, Then I get no speed when coasting,
