4. Ajuster les paramètres : Navigate through the software interface to access various adjustable parameters. These typically include:
   • Limitation de vitesse: Adjust the maximum speed at which the motor provides assistance.
   • Niveaux d'assistance au pédalage (PAS) : Customize the power output for each pedal assist level. This can make the throttle smoother or allow full throttle acceleration in PAS staget.
   • Réponse de l'accélérateur : Modify how the throttle responds, for example, to make it less like an on/off switch and more gradual.
   • Limite actuelle: Adjust the maximum current draw (e.g., from 25 amps à 18 amps) to potentially extend battery and motor lifespan without significant performance loss.
5. Write Parameters: After making desired adjustments, use the 'Write' or 'Program' function within the software to apply the new settings to the motor controller.
6. Vérifier les modifications : Disconnect the cable and test your e-bike to ensure the changes have been applied correctly and the motor operates as expected.

  • Essayez un autre port USB sur votre ordinateur.
  • Verify that the motor controller is powered on (e.g., e-bike battery connected and turned on).
  • Check your computer's Device Manager for any unrecognized USB devices or driver issues. You may need to manually install a USB driver if not automatically detected.
• Problèmes de compatibilité logicielle :
  • If using Windows 10 and experiencing problems, try running the software in compatibility mode for Windows 7 or 8.
  • Ensure the software is always run as an administrator.
  • Download the latest version of the programming software from a reliable source.
• Parameters Not Applying:
  • Confirm that you clicked the 'Write' or 'Program' button in the software after making changes.
  • Ensure there are no error messages displayed in the software during the writing process.
  • Double-check that the motor controller is properly connected and powered throughout the process.
• Motor Not Responding After Programming:
  • If you saved a backup of your original settings, try loading and writing those parameters back to the controller.
  • Review the changes you made for any extreme or illogical values.
