Bosch EDC17CV41 — a Common Rail diesel ECU built on the Infineon TriCore core. Firmware protection combines a software calibration CRC and a cryptographic signature (RSA/CVN) over the CFG and CAL areas; after editing, these sums must be recalculated or the unit will reject the file.
This unit is found on дизельных vehicles Agrifac, BMC, Bravo, Challenger, Claas, Doosan, Fendt, Ford Trucks, Grim, Guaresi, Isuzu Trucks, JCB, Komatsu, Kuhn, Landini Tractors, Lannen, Laverda Agri, Liebherr, Ljungby Maskin, Logset, Massey Ferguson, Merlo, Miller, Minelli, Profi, Ravo, Sampo, Sor, Storti, Supertino, Tatoma, Temsa, Tigercat Tractors, Valtra, Vermeer (2008–2023) — a total of 55 models, among them Agrifac Condor, BMC Tugra, Bravo Rotomix, Challenger MT800, Claas Arion, Doosan Crawler Excavator.
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.
