so the tune i need to run my car is in one of my x3's. whenever i hook it up to the car to try to flash it in, a download error comes up and it wont do it. i have a new x3 that works, but it doesent have the right tune in it. is there any way i can pull a tune off the bad x3, save it to my computer, then put it back on the new x3 so i can flash the car?
