Bosch MEDC17.5 — a Mercedes Common Rail diesel ECU on the TriCore core; the calibration checksums and signature are recalculated after editing.
This unit is found on дизельных vehicles Mercedes-Benz (2008–2018) — a total of 11 models, among them Mercedes-Benz C200 CDI, Mercedes-Benz C220 CDI, Mercedes-Benz C250 CDI, Mercedes-Benz E220 CDI, Mercedes-Benz E350 CDI, Mercedes-Benz ML 250 BlueTEC, with power output of 136–265 hp
Recalculation is needed after any calibration edit — Stage 1 OM651 (170 → 215 hp / 400 → 480 Nm), Stage 1 OM642 (258 → 320 hp / 620 → 720 Nm), AdBlue/SCR off (BlueTEC — обязательно), DPF off (физический + калибровочный), EGR off (по обоим bank-ам для V6), NOx sensor delete, DTC removal (P204F/P11AA/P229F), Throttle valve disable, Speed limiter 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.
