I’ve got my Bafang bbs02 750w on my beach cruiser. But there is an issue with throttle thumb, it responds with delay and push transmission very hard. I think this may cause problems to nexus 8 hub and for chain too.
I want to fix gap between time when I starting throttle and when motor begin to reform as well as fix very high motor power on start.
I’ve got a programming cable, but it seems broken from beginning. I have tried several Windows PCs without success. Then I decided to break down cable to see what exactly inside.
Now I have a cable and broken serial programmer. I can buy new one, but now I need to figure out how to connect wires to new usb serial programmer (which I'm going to buy).
Also I found weird connection in my actual cable implementation (plz see photo).
Here is a cable:
Here is old not-working programmer:
And you can see strange connection here: white and black cables are connected to RXD, and blue connected to TXD.
Should I connect new usb serial device in the same way to the cable or should I use another scheme?
Some advices about throttle gap and power fix also appreciated.
Also, I'm going to drive on throttle only.
Thanks in advance!
