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