Bosch EDC16C31 — a previous-generation Common Rail diesel ECU (ST10/MPC core). Its checksums are simpler than the EDC17, but when maps are edited they must be recalculated across several areas at once.
This unit is found on дизельных vehicles BMW, Mitsubishi, Toyota, Volvo (2002–2010) — a total of 17 models, among them BMW 3-Series, Mitsubishi Colt, Toyota Auris, Volvo C30, BMW 5-Series, BMW 7-Series.
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.
