Engine 2.0 diesel, 1.8d version
ECU EDC17C06

The BMW E91 Touring is badged 1.8d and has an EDC17C06 control unit; the video describes its engine as a 2.0-litre diesel. Factory output is 143 hp and 300 Nm. Before tuning, a run with the original file recorded 154 hp and 332 Nm.

A new engine calibration was prepared for the car. The video states that the emissions systems remained installed. The dyno run was performed in fifth gear with the manual transmission.

After tuning, the dyno recorded 187 hp and about 388 Nm. Since the initial dyno result was already above the factory power figure, the most useful comparison is between the two measurements from this vehicle.
