MINI One 1.4 D — ECU calibration and power test

A MINI One 1.4 D was dyno-tested, its ECU calibration was revised, and smoke-opacity readings were compared.

This 2003 MINI One 1.4 D came in for improved engine response and a check of how the changes would affect smoke opacity. Before the work, the car was measured on a dyno with its existing software: 72 hp and about 178 Nm. That was below the factory figures quoted for this engine, 75 hp and 180 Nm.

After ECU calibration, the engine produced 86 hp and approximately 203–204 Nm. The software settings for the EGR system were also changed. The smoke-opacity coefficient was 1.0 before calibration; repeat checks afterward recorded values of around 0.97–1.0. The measured power increase was therefore not accompanied by a higher opacity coefficient.

Given the vehicle’s age and the data collected during testing, no further power increase was made. The result was checked on a dyno; the video does not identify the ECU model.
