RaceChip GTS 5 Black for BMW X3 M50 (G45) – The Best Solution for a Locked ECU

The RaceChip GTS 5 Black is the ideal performance upgrade for the BMW X3 M50 (G45). This model is equipped with a factory-locked ECU, which means ECU unlocking and traditional flash tuning are currently not possible. As a result, conventional remapping cannot be performed at this time.

With optional app control, you can manage performance levels directly from your smartphone and switch between RACE, SPORT, and ECO driving modes.
