Siemens (Continental) SIM266 — a Siemens/Continental petrol ECU; the calibration checksums are recalculated after the firmware is edited.

This unit is found on petrol and petrol/cng vehicles Mercedes-Benz (2004–2009) — a total of 3 models, among them Mercedes-Benz A-Class, Mercedes-Benz B-Class.

Recalculation is needed after any calibration edit — Stage 1, Stage 2, Stage 3, Pop & Bang / decat, Launch control, Speed limiter off, OPF/GPF off, Lambda off, DTC removal, Cold 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.
