Vishnu Tuning's Procede is already available for the Z4is and 335is, which share the same Siemens DME as the 1M and almost identical tuning. The Cobb Accessport should be ready shortly.

AFAIK, the single difference between the "is" models and the 1M is that the 1M has the M button which creates more aggressive throttle response.
