At least in the past, this would not happen: the dealers (if doing an update) overwrote everything that was there.
So if you had a tune, then the manufacturer fixed a recall (as an example), updated your ECU (and they do NOT ask you if you take the car in - if the books say an ECU update is necessary they do it), your tune would be over written.
You then need to send it back and get the tune either reinstalled and thus loosing the recall fix (or whatever reason the manufacturer felt they needed new software in the car). Or you wait for the tuner to come out with a new version that has the fix in it, then send it in.
I don't know GSR, but ECU tuners usually don;t have a problem keeping you up to date. So all great news from GSR and I'm keen to keep an eye on M235i progress.
