Hey guys. How does OTA Remote Software Upgrade and flash tunes work. Does it affect the tune? Or are are the updates more to do with idrive and other options rather than DME updates

If you do OTA your tune will be removed

OTA updates remove flash tunes AND locks the DME. Reflash requires the DME to be removed and bench unlocked. I gave up flash tuning and put a piggyback on. Not worth the hassle.

TurboTransformer. By far the best bang for the buck and a great Bluetooth interface.

Do we know whether MHD/BM3 will be able to update their flashes so we don’t need a bench unlock for those DME’s that were a pre June 2020 DME (and have been locked over the air or through BMW).

Anyone?
