P08 Speed limit. Range: 0-50km/h, 50 means without limit No-Communication Status (controlled by the meter): when the real speed is over the ones we set, the meter would shut off PWM output; when less than the speed we set, the meter would turn on PWM output automatically, the driving speed would be ±1km/h; (Speed limit is for PAS, not for Throttle) Communication Status (controlled by the controller): The driving speed keeps same with the ones we set. Random error: ±1km/h.
