MG flasher with custom map

[igorko82]

Hello, i have a custom map flashed in my g20 330e by an local tuner, and now i want to use the MG flasher to have possibility to switch maps, go to stock and back etc. the question is, will mgflasher read this custom map from ecu and it will be available to flash to it, or it will be overriden by mg flasher an i will not be able go back to this map?

i think this may answer your question from mg flasher manual

Flashing stock – original software​

There will always be an original/stock flash available, it is automatically created with your license activation. You will be able to restore the ECU back to stock at any time using “Stock” button available from the Flashing screen – it is Stage 0, original factory software. ECU/Car remains activated/unlocked. Choose this option when you planning to visit service - flashing counter and CVN is kept the same (short flashing time of 15 – 20 seconds).

Talk to your tuner. He should be able to send you the tunefile which you can upload via MG falsher App. But Mapswitch is part of the custom tune.
