Hello, Please help! Stuck, need help hacking controller and or 750c blu display. Have 1,000w Bafang geared rear hub kits, installed everything, everything works except for PAS. I noticed the manufacture sent me only left small pas and did not include the larger right chainring side pas which I normally always use. PAS is not working, I switched out controller three difference small PAS and then seller says small pas won't work, only large pas, I only have one I installed it, still not working, Brake level shut off works, throttle works, front light works, battery works, everything is working except for the PAS. When I go to into the 750c blu display go to advanced setting using 1919 password, I can change pas number, but not magnets or really anything else. Erorr section is all dot dot for - - - - whatever that means. I am told that I need to change the magnets setting, Is there a way to hack these controllers and display? HELP Customer waiting!!! STUCK!!!
