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. 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.
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 E50.
Switching Between Maps
Gen 1 F-Series B48 Information
We added stock power levels to which you can immediately switch, 184 bhp or 252 bhp, depending on the car and 252 bhp.
Gen 1 F-Series B58 Information
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 E30. We also added additional power levels to which you can immediately switch, Stock, Stage 1+ and Stage 2.5. Stage 2.5 has been made independent of Stage 2 as of June 2021 map v2.15, more information below.
Upgraded High Pressure Fuel Pump support
From the flashing menu, select the HPFP Installed option for B58TU pump, Spool Performance FX-150 & FX-180 or Dorch Engineering Stage 1 & 2. This will allow the ECU to properly control the pump. To gain any significant performance benefits of these high flow pumps, you’ll also need to select a Stage 2.5 map.
When using Stage 2.5, it is required to have an upgraded HPFP (B58TU, Spool Performance FX-150 and FX-180 or Dorch Engineering Stage 1 and 2) and downpipe.
To prevent unintentional damage, do not switch to this map without installing these upgrades and selecting HPFP Installed in the flashing menu first.
Limitations
Switchable map can only be achieved under the following conditions:
Switchable maps must be available and enabled in your software (selected during flashing process). Currently, only available on F-Series Gen 1 B46/B48/B58 (non hybrids). G series will be available soon.
Engine must be running (more than 30 seconds from start when using Custom Code v5.4 and earlier, Custom Code v6.0 can be used as soon as engine starts)
