Starting with Custom code v7.1, Switchable Maps are supported on Gen 2 B48 and B58, however OTS maps for Gen 2 cars do not have the Switchable Map slots populated. This includes the following OTS map versions:
v2.15, v2.16 (Gen 2 B48)
v3.15, v3.16 (Gen 2 B48)
v2.22, v2.23, v2.24 (Gen 2 B58)
We will be updating OTS maps in the future to populated the required slots. In the meantime, we recommend users interested in utilizing Switchable Maps to reach out to Custom Tuners who can provide their own OTS maps with switchable map slots populated. See our list of recommend custom tuners here: Custom Tuners list
Switchable Maps brings the ability to change between maps in real-time, without reflashing your car! This means you can change from a 91 OCT / 95 RON calibration to a 95 OCT / 102 RON with the press of a button by using your steering wheel controls or the in-app diagnostic menu!
Infographics are available (one for Stage 1 and another for Stage 2) to help identify where you can find a given fuel type or power level. Columns are the selected file flashed to the car (identified by ACN 91, 95 RON, 98 RON, 100 RON and 102 RON) and rows are the slots you can cycle through On-The-Fly once the car is running. The octane level you select before flashing is the default (slot #0) map that is active after flashing. Slots 1 - 4 will contain either a lower/higher octane level, or ethanol. When the map is flashed, you can view the available slots (for the flashed file) on the MyCar page by tapping the ECU info area (MG Flasher App v277 or higher). You can also find this information in the OTS map release notes.
Calibrations for 102 RON (95 OCT), 100 RON (94 OCT) and ACN 91 (for low quality 91 OCT / 95 RON) have been added to the list of choices when picking a file to flash. The octane level you select before flashing is the default (slot #0) map that is active after flashing. Slots 1 - 4 will contain either a lower/higher octane level, E30 or E50E40.

In case your BMW does not have SPORT+ mode you will be limited to Slot #1, #2, #3 and reverting to Slot #0 is possible from SPORT mode by the same sequence - SPORT and 2 quick MSA presses Within the 5 seconds of holding the Gas Pedal at W.O.T position (while still holding the Brake Pedal) you will notice the RPM on the dash will reflect the choice you have selected (ie. 3000 RPM = Slot #3). Release the Brake and Gas Pedals fully to exit the selection process. RPM on the dash will return to actual engine RPM and the Check Engine Light will stop blinking.
