Bosch MD1CE100 — a latest-generation diesel ECU on the Infineon AURIX (TC2xx/TC3xx). Its protection is multi-layered: a calibration CRC, a digital signature and container checksums — recalculation is mandatory after any change to the dump.
This unit is found on дизельных vehicles Doosan, Howo, MAN Truck & Bus (2019–2022) — a total of 4 models, among them Doosan Crawler Excavator, Howo N 6X4 Tractor 12L 6L, MAN Truck & Bus Tgx.
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.
