Motorola/NXP EMS6 — online firmware checksum recalculation. Upload MOD and ORI — result in a second, preview is free.
The plugin is already selected. Upload your MOD and ORI firmware — you'll get the result in a second.
Motorola/NXP EMS6 — a Siemens/Continental petrol ECU (Jaguar/Land Rover/Volvo); the calibration checksum is 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.
Other checksum plugins from the same manufacturer — open any of them to recalculate the checksum.
