Bafang M400/DP C07.UART speed setting problem

Hello everyone, i'm new here and i have tried to find a soluton in other topics and google but i can't seem to find the answer.

i recently got a new bicycle with the bafang M400 motor and everything workd fine but i would like to go a little faster, it's my understanding that it's possible to just change the max speed in the settings menu but when i enter the menu there is no way to enter the password the enter the ''special'' menu.

Does anyone know what i could do? (appart from a speedbox)


thx!

somebody?

I assume you have the Bafang Max motor. Here are a few threads you may find useful:
