JB4 app issue
 

Need help I installed my new JB4 to my N20 bmw 328i I have the wireless BT connection. In the app I’m able to read the cars codes which are all fixed now so now I don’t have any codes. But gauges do not read and I feel if there’s no change in performance. I’ve tried unplugging harness and running the car stock then putting JB4 back in and same thing happens any suggestions?
