Bosch MG1CP007 — a latest-generation petrol ECU on the Infineon AURIX (TC2xx/TC3xx). Its protection is multi-layered: a CRC, a digital signature and container checksums — recalculation is mandatory after any change to the dump.
This unit is found on petrol vehicles Porsche (2019–2025) — a total of 9 models, among them Porsche 911 Carrera, Porsche 911 Carrera 4, Porsche 911 Carrera 4 GTs, Porsche 911 Carrera 4S, Porsche 911 Carrera GTs, Porsche 911 Carrera S.
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.
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.
