So I got my Dinan Sport Performance Tuner today. But something isnt right. I'm hoping someone may have an idea of whats going on or can point me in the right direction.

I installed it to the pressure sensor like the instructions say. Turned on the ignition. The red LED light came on. I then used the app to select my engine and calibrate the boost gauge. So then I started the X3, and was immediately greeted by a message saying "Drivetrain Malfunction" with a check engine light.

I disconnected the Dinan Sport and just plugged my pressure sensor back in, and everything was back to normal.

Any ideas?
