Bosch MG1 — frequently asked questions
Which Bosch MG1 ECUs does Map Decoder support?
16 models are covered: MG1CP002, MG1CS001, MG1CS002, MG1CS003, MG1CS008, MG1CS011, MG1CS015, MG1CS016, MG1CS017, MG1CS019, MG1CS031, MG1CS036, MG1CS042, MG1CS111 and 2 more.
What can Map Decoder do on an MG1 file?
Across the family the validated operations are Catalyst Off, Lambda / O2, MAF Off, NOx Off, OPF / GPF Off and Throttle Valve (TVA). Availability differs per model — the ECU page lists exactly what is supported for that model.
Does Map Decoder correct MG1 checksums?
Yes. Checksums for the regions a patch changes are recalculated automatically during patch generation.
How many DTC codes are mapped for MG1?
8,690 distinct diagnostic trouble codes are stored across the family, each with an address and byte values measured on real files.
Tune Bosch MG1 files
Map Decoder analyses Bosch MG1 files, detects the maps and generates a verified patch with the checksum corrected.
