When might the AccessPORT be available for the N54s with the MSD85 DME (Z4 sDrive35is, 335is and the forthcoming 1 Series M Coupe)?
As I understand it, the tune in these three models -- each of which has a 7-second overboost feature -- are very similar except that the 1M will have an M Drive button sharpening throttle response.
Thanks.

P.S. I promise not to ask this question more than once a day
