Hey there,
i just got a an BBS02 and the setup is working good so far, even with a 7,5ah bottle battery, i have enough energy to make my way to work twice, which is quiet steep. I flashed the BBS-FW by danielnilsson9, so i can switch between normal and sports mode. Everything is working out fine, but i have the issue that i need to pedal too fast to make the PAS starting the motor. On the orignal FW, the motor started so fast, it even happened that i accidentally triggered it. Now i need 2-3 fast crank rotations. I set the starting angle to 45° but it didn't change anything. -Can someone explain to me, what i have to do? Also is there a way to set a smooth decay for PAS. When i stop pedaling, the motor really slaps and its loud. If i do the same with the throttle, it just buttery smooth stops giving power.

Best Regards and thank you!
 
To help future readers with similar issues, what specific settings were wrong, and what were they set to, and what *should* they have been set to? :)
 
I used a to short timing for the motor cut off. This not only defines the cut off from when you let go the pas paddling but also how short the intervals between the pas are before starting to assist
