Description
If your N63TU DMEs are running older software (anything other than the 012214 ROM, as shown in BM3), you’ll want to upgrade them to newer software (012214 ROM) to make all tables available for custom tuning (note that some ROMs don’t support BM3 OTS maps properly). This service usually takes 1-2 hours. An ENET cable, Windows laptop, and a good battery charger that can supply at least 20A to the car are required. This service is included in the advanced tuning package (if needed).
