I did not get a file from gearhead I am still waiting to be able to access anything on that site. I will look that up and see if that will work. Thanks

Use an OBD Link LX Bluetooth adapter and use an android device with ls droid installed and it will read the ecm and store it as a bin file.

Wanted to see if anyone had the xdf files for an 03 p59 os 12579405 application? Tried getting it and no luck yet. Also having trouble getting someone to program it. any help would be appreciated. Tried joining the gearhead site and no luck yet
