Default Jb4 not working - 05-29-2021, 03:30 AM

I picked up my jb4 yesterday for my 2015 BMW 750i (N63TU2) and I installed it. For some reason, it's not running right. I started to run map 1 and it will run super rough and the same as map 2. It will automatically boot me to map 4. Maybe I'm not too familiar with the whole process since I'm super new to this. Please let me know what I'm doing wrong. Does it have anything to do with the firmware? Do I need to download another one? I have no idea what I'm doing wrong.
