About this file
Stage 1 on this engine raises the injected fuel, the boost and the rail pressure and lifts the torque limiters, within what the standard turbo, injectors and clutch hold. The smoke limiter follows the new airflow, so a healthy engine pulls harder without black smoke.
The file is listed for the 110.3 kW, 150 hp version of the BMW E46 320D. Check the power on your car's papers: the same model was sold with several engines, each with its own file.
For software 361858 of the BMW E46 320D we sell the original, Stage 1 and Stage 2, each made from the same original read. Every file downloads straight after payment.
Read the Bosch ECU with your usual tool and keep the 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 added to 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).
Hardware 0281010565 is the number on the Bosch ECU's label. Software 361858 (1037361858) is the calibration inside it: a read with hardware 0281010565 and another software number needs a different file.
