This 2012 Audi A6 with a 2.0 TDI engine and an EDC17C46 control unit came in for a power increase. All emissions systems remained fitted and in place.

Before ECU calibration, the dyno recorded 182 hp and 408 Nm, compared with the stated factory figures of 177 hp and 380 Nm. After the software was revised, the final measurement was approximately 235–236 hp and 486 Nm.

The calibration was therefore carried out without changing the emissions-system configuration. The video shows both the initial dyno run and the result after the ECU software was adjusted.
