Delphi DCM3.7 — a Delphi Common Rail diesel ECU (Renault/Nissan/Dacia/PSA). It has its own checksum logic, which the solver recalculates correctly after a calibration edit.
This unit is found on дизельных vehicles Hyundai, Kia (2007–2014) — a total of 10 models, among them Hyundai Grand Starex, Kia Bongo III, Hyundai H-1, Hyundai I20, Hyundai I30, Hyundai Iload.
Recalculation is needed after any calibration edit — Stage 1, Stage 2, DPF off, EGR off, AdBlue/SCR off, DTC removal, Flap off, Lambda off, Speed limiter off, Torque monitor off, Hot 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.
Other checksum plugins from the same manufacturer — open any of them to recalculate the checksum.
