I just got my X3 yesterday and i cant get the tuner to let me make any adjustments. I followed all the instructions on updating before i plugged it into the car and everytime i go to strategy tune or custome tune it gives me an error. I tried to return it back to stock and it tells me it already is stock. Does this mean that i cant do any adjustments until I get a tune for the car. All I want to do is turn off the shift point, T/C, and speed limiter.
