This work concerns a diesel BMW X1 F48 with an EDC17C50 control unit. The video is presented as a before-and-after comparison around ECU calibration.

Before preparing software, the exact control unit and vehicle software version need to be identified. This helps select a compatible file and compare how the car behaves at each stage.

No specific power or torque figures are provided for this vehicle, so the article does not assume or promise a particular gain.
