Haibike Urban Plus OEM accessories

Hey guys, I bought my bike used and I was wondering what I'm missing? I basically just got a complete bike. I saw in Court's Electric Bike review there's a usb dongle for this bike and I think he mentions you can change the amperage settings for the motor. I am thinking mine is set lower than usual but I have no way of confirming that. Does it also come with some software on a CD? can you adjust the assist levels? Also, what are your top speeds on this bike? I still have to figure out fixing the cobi system but as soon as that is fixed I want to focus on making sure everything is right!

heres it detailed somewhat in the video review:
