all i know is that: we need':
-A TTL converter (cheap off ebay)
-A special cable
-A computer and a software
any more? hope this is a start..
Don't forget to cross rx and tx such that tx (transmit) of your USB to serial go to rx (receive) on the controller.
programming software from BAFANG http://ulozto.cz/x1zej9PD/software8fun-zipp rename to *.zip
multi language programming software (english , español, french, german, italian, portuguese, swedish, turkish)

I had to install a driver for the converter to work properly. You just have to know the chipset ref and it is easy to find online.
Rather than trying to find the same 5pin connector as on bafang wiring harness, I installed another plug (common jst-xh 5pin) in serial between the connector and the display.
I opened the display case (which is welded so the result isn't very clean ...). You can see on the pic the wire's color and function.
You need to connect GND, RX and TX of the controller to the converter (TX display = RX controller = TX converter) AND to connect the red and white wires (named D+ and Ds in the display) together.
D+ is the battery positive, Ds is the wire that awaken the controller when connected to +batt.
This way, the programming software is working fine.
All the controller parameters are not so easy to understand, so the more people will be able to have this software working, the sooner we'll be able to master it for fine tuning of this great litttle product.
