I have visited their site and it seems that they have a solution for 740i N54 motor (model 2008-2012)
I'll be in touch with them to ask if they really support F01 740i N54.
The point is that this car has Continental MSD87.2 DME which can not be tuned via OBD...

Unfortunately their answer about support was "cloudy".They don't really know f.e. how much torque limiters are upper the stock values.I said that my car is tuned to aprox 380 ps and 530 NM and TCU doesn't allow the full power because of those limiters...and their answer was that they can't guarantee that my tune will work properly.This means that they have no idea about their tune values...F.e. They should say to me that "TMCmotorsport tune torque limiter values for your car is XXX Nm"...
I decided to stay away...
