Bosch DCU17CV51 — a heavy-duty Common Rail diesel ECU (Iveco/MAN/DAF/Volvo) on the TriCore core; the checksums are recalculated after editing.

Recalculation is needed after any calibration edit — Stage 1 truck, AdBlue off, DPF off, EGR off, Limiter speed/RPM, DTC removal, Cold-start fix: 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.
