About this file
An original holds every map as the factory wrote them: injection quantity and timing, boost and rail pressure, the torque and smoke limiters, the speed limiter and the emissions controls. Tuners start a file from it; workshops use it to put a car back to standard.
The file is listed for the 110.3 kW, 150 hp version of the Ford Focus 1.6TDCI. Check the power on your car's papers: the same model was sold with several engines, each with its own file.
This file of software 522019 of the Ford Focus 1.6TDCI is checksum corrected and downloads straight after payment. Another stage of it can be built from your own read by our engineers.
The Bosch MED17 ECU in this car is read and written over OBD and on the bench, with tools such as Autotuner, CMD Flash, MagicMotorsport FLEX, Alientech Kess V2, Dimsport New Genius and Dimsport New Trasdata. Keep your own read: compare its hardware and software numbers with the ones on this page before you write the file.
DPF off, EGR off, AdBlue (SCR) off, DTC off and speed limiter (Vmax) off can be built on this file on request, for off-road and competition use: send us your read through our file service and our engineers add them (any file £50, from £30 in packs).
Software 522019 (1037522019) is the calibration inside the Bosch ECU.
