Bavarian Technic Cable Diagnostic Software, and Drivers, maps

Hello there guys.

Where do I download the required software for the Bavarian Technic Cable Diagnostic
cable? I bought the cable used, and they said, there are 2 vins left. I bought it on ebay, and it came with no software.

Where do I download usb drivers, and which maps, or tweaks are good for my bmw?

I have a STOCK 2007 bmw 335xi . What can I really do with this cable?

The only tuner I have right now is the JB+.

Thanks guys.
