RaceChip GTS Black (2019-2020 M5, 2020-2020 M8) - 918515
Even nominally identitical engines often perform slightly differently. This can be down to manufacturing tolerances, the number of kilometres covered or the quality of the fuel. So that your RaceChip works perfectly with the engine in your car, we have developed fine tuning mappings. They mean that you can fine tune your GTS or GTS Black to match your engine’s performance and characteristics perfectly. The app control feature lets you download the pre-programmed settings right from our servers.
