No tune on mine and never has been.My take on this as OneExtra suggests is getting the engine up to normal oil temp sensibly and is imperative to long engine life.High outside ambient temperatures and constant full boost operation can test your oil to the maximum and certainly the higher the tune means more common sense should be taken when 'gunning it'. Full throttle in manual mode when moving in low gear is a definite no and should never be used. There are also the types, makes and grades of oils used and it's suitability in different climates which has been discussed here exhaustively, just use the one recommended by BMW in your country with the correct specifications.
