Itīs not only an rumor !!!
Until today no one has ever tuned an BMW F..-Model ECU. Also well known tuners with tight relations with BMW as AC Schnitzer only offer Tuning-Boxes (piggybacks), because it is nearly impossible to tune the ECU itself. According to my informations there are not alone electronical/software problems but also simple "mechanical" problems to open the ECU-box without destroying it ... minimum one of two boxes breaks if they try to open it -
the most simple tuning blocker!!!
