Bosch DCU17PC42 — a heavy-duty Common Rail diesel ECU (Iveco/MAN/DAF/Volvo) on the TriCore core; the checksums are recalculated after editing.
This unit is found on дизельных vehicles Caterpillar, Iveco, MAN (2010–2020) — a total of 5 models, among them Iveco Daily 2.3 HPI, MAN TGL, Caterpillar Industrial C-engine, Iveco Daily 3.0 HPI, Iveco Stralis, with power output of 136–460 hp
Recalculation is needed after any calibration edit — Stage 1 truck (10-15% мощности, 15-20% крутящий момент), AdBlue/SCR off (для truck-применений требует проверки региональной законности), DPF off (физическое + калибровочное удаление), EGR off, Speed limiter off (vmax — для off-road использования), RPM limiter raise, Cold-start fix (industrial), DTC removal (P204F/P2002 — типичные AdBlue/DPF ошибки), Torque monitor off: the checksum no longer matches, and the ECU throws an error or refuses the firmware.
Upload the modified file (MOD) and the original (ORI) — the tool compares them, finds the affected regions and recalculates only the required checksums, leaving the rest of the calibration untouched. The result is ready in a second and free; downloading the fixed .bin requires registration in the portal.
Other checksum plugins from the same manufacturer — open any of them to recalculate the checksum.
