Important Information

XDF files are digital definition files intended for users who understand ECU calibration, binary editing, and the risks associated with modifying vehicle software. An XDF does not include a tuned calibration file or guarantee that every parameter within the binary has been defined.

Files are provided for the verified software version and selected package. They may not be compatible with files from another vehicle, software version, operating system, or controller revision.

All files are provided at the purchaser’s own risk. 4J Tuning assumes no responsibility or liability for improper use, incorrect file selection, vehicle damage, controller failure, data loss, emissions-system changes, or any other consequences resulting from the use or modification of these files.
