Bosch EDC17C11 — 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 Nissan, Opel, Renault, Vauxhall (2010–2012) — a total of 6 models, among them Nissan Nv400, Opel Movano, Renault Master, Vauxhall Movano, Nissan Primastar, Renault Trafic.
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.
