New MTB E-bike from Biltema tuning

Hello. I am a machine engineer from Sweden needing some advice from electronics specialists in here. I have read a LOT trying to understand E-bikes bout I am still not yet quite sure. For a couple of weeks ago I bought a new 36V, 8,8ah 250w MTB from biltema, see picture 1. Its a copy of a copy of a copy (diavelo bragi atb, protanium etc.) It has a 8FUN rear motor and C965 display. The controller is an LSW70A6G, se Picture 2, 3, 4 and 5.

The motor helps me pretty good up to about 23 km/h and then the assist decreases and turn off at 25 km/h. When I type the controllers password in (1919) the motor doesnt turn of until the set value, up to 45 km/h. But still after abot 23 km/h the assist from the motor is almost to low to sense. So I assume the speed limit is also set in the controller.

Now for the questions if anyone helpful out there could answer me. I want the motor to help me above 25 km/h, around 32 km/h would be nice or by the displays command. As you see in Picture 2 the is a separate White wire for connecting to a computer and programming as I understand (board with Infineon chip I hope). Could I use the software intended for programming Bafang BBS01/BBS02 or the software parameter designer.exe (no speed setting by displays command in this one?)?

If any more information/data regarding the details is needed I will give you that.

Regards
