JB4 Problems. Help please?

Just hooked up my JB4 G5 to my 2012 135i vert. I dont think it is interfacing or working properly. I have checked the harness plugs at least 727272 times. Ha. But the car starts and indles/runs fine. It just doesnt seem different power wise. . I also noticed, when using the steering wheel controls, the rpms only vary by 650 per map. Instead of 1000 intervals. Seems wrong to me? Any ideas would be appreciated!

Also nice, as you learn how to change settings and different functions on the sterling wheel controls.

Glad you got it figured out The JB4 comes calibrated for a 335 out of the box (in terms of cluster settings)
