Problem: A frequently reported issue with the Speedway III & IV, is that the speed is off from true, or the battery runs out a long way before it reaches 0%.
Solution: this occurs if the system defined P values have been changed/altered from correct settings, please check & adjust if necessary to:
- P0 = 10, the tire diameter size
- P1 = 52, scooter’s voltage
- P2 = 10, number of magnetic poles in the motor
