Enter the settings for tire circumference and "signal" divider". For example, 1480 mm circumference, and the signal divider is "one" (P-001). Then double-check your wiring; from speed sensor RED connects to Ace GREEN, and speed sensor WHITE connects to... Ace BLUE on your Acewell? Try connecting speed sensor WHITE directly to GROUND.
On my bike I connected my speed sensor white directly to ground, entered the settings, and it all works!
