Australia 1st Nov 11 Hi Andrew Wanted to drop you a note to advise that the unit is operating very well, the X5 characteristics have changed and the acceleration is much more responsive. The torque improvement is very noticeable, the change has made the car feel much lighter due to this change. As I mentioned it is on Map 3 and -10% and have no indication of any fault or code error by ECU/body ECU since changing to this setting. Fuel consumption has begun to drop from 10.1 to 9.3/100k when driven normally to and from work with mix of Hwy and suburban roads. In summary this has been a very good exercise so far, thank you for your assistance and product supply. Best wishes Percy
