FunctionChecksum recalculation

Delphi DCM3.3 — a Delphi Common Rail diesel ECU (Renault/Nissan/Dacia/PSA). It has its own checksum logic, which the solver recalculates correctly after a calibration edit.

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.

Загрузи оригинал (ORI) и изменённый файл (MOD) — инструмент сравнит их, найдёт затронутые регионы и пересчитает только нужные суммы, не трогая остальную калибровку. Результат — за секунду и бесплатно; скачивание исправленного .bin — после регистрации в портале.
