Bosch EDC17C46 — a Common Rail diesel ECU built on the Infineon TriCore core. Firmware protection combines a software calibration CRC and a cryptographic signature (RSA/CVN) over the CFG and CAL areas; after editing, these sums must be recalculated or the unit will reject the file.

This unit is found on diesel vehicles Audi, Seat, Skoda, Volkswagen (2009–2018) — a total of 12 models, among them Audi A3, Volkswagen Golf, Skoda Octavia, Seat Ibiza, Audi A1, Volkswagen Polo, with power output of 90–170 hp

Recalculation is needed after any calibration edit — Stage 1 (200-220 hp / 380-420 Nm для 2.0 TDI), DPF off (физическое удаление + калибровка), EGR off (закрытие клапана + удаление DTC), AdBlue/SCR off (для 2.0 TDI с AdBlue), Flap off (вихревые заслонки), Lambda off (NOx сенсор off), Hot start fix (Common-Rail инжекторы), DTC removal (P0299/P2002/P00C8), Speed limiter off (vmax), Torque monitor off: 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.
