Hey folks,

I have some software issues with my bafang M420. I do have the cables to connect to the canbus and adjust things like speed and such with some software i found around here. Since a while the bike is giving me errors and the shop wants to replace the engine for a new one... I am wondering if i can just''hard'' reset the engine by installing the default original firmware. I am asking this because when the shop updates the bike or whatsoever they dont remove the speed limit and other things i set. So they are not completely overwriting the existing software. Any ideas on this?

Thanks
