Motorola/NXP CM871 — after a calibration edit the firmware checksum must be recalculated.
This unit is found on дизельных vehicles International (2008–2009) — a total of 9 models, among them International 5900 Series, International 8600 Series, International 9200 Series, International 9400 Series, International 9900 Series, International LoneStar.
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.
