Volvo V70 D5 — correcting the existing ECU file and testing power

Diagnosis of uneven running, ECU file correction and power testing for a Volvo V70 D5 with EDC15C11.

ECU file correction diagnostics dyno testing
Date 24.11.2020
Vehicle Volvo V70 D5
Year 2003
Engine 2.4 diesel
ECU EDC15C11

This 2003 Volvo V70 D5 with a 2.4-litre diesel engine and an EDC15C11 control unit arrived after being tuned at another workshop. Following the previous remap, the car accelerated unevenly and hesitated, particularly under load.

The existing file was read, analysed and revised. After the new program was written and a road test completed, the owner confirmed that the hesitation had gone and the engine gained speed more smoothly. The spoken section gives the previous file's dyno result as approximately 184 hp and 470 Nm.

The video title lists gains of 43 hp and 153 Nm, corresponding to about 206 hp and 493 Nm when compared with the original figures stated in the title. These figures come from the title; the spoken section does not clearly state a final post-correction dyno reading.
