This 2005 BMW E60 with a 3.0-litre diesel engine and an EDC16C35 control unit arrived with software calibrated by another workshop. Before remapping, the dyno recorded approximately 260 hp and 531 Nm, compared with the stated standard figures of 231 hp and 500 Nm.

The existing file was analysed and revised, then a new ECU program was prepared for the car. The video title lists 309 hp and 656 Nm for the new calibration.

The work aimed to replace the previous file and check the result on a dyno. The final figures appear in the video title but are not repeated in the spoken section after remapping.
