Ive done quite a few OTA updates in my life while my cars had actual DME, non piggy tunes, zero issues. Now an OBDII update could wipe it.
Of course nothing is certain in life but two things ....

DME? Found dmetuning.com and they list a M850i but only a 2020. Same for a M8/M8C as in June of 2020 BMW deployed the locked ECU. Mine's a October 2019 build but it's been widely reported on the forum that subsequent OTA's locked the ECU regardless. Fact or fiction?
Description on the DME site is "Expertly calibrated and meticulously refined, DME Tuning’s ECU software is guaranteed to give you MORE of a good thing." If the ECU is locked then I guess that's a no go.
