BMW E60/E61 535i/xi SAT (Sport Automatic Transmission) Flash

This client wanted an SAT (Sport Automatic Transmission) flash for his E61 535xi. After wading through some conflicting instructions we figured out that the VO needs to be changed and the EGS (transmission control) module needs to be flashed with WinKFP adding the SAT calibrations, we did not change the gear selector.

After taking it for a test drive the client was very happy with the improved shifts.
