Title: BMW MG1 – Availability of ELF or linker map files for reverse engineering? Post by: GBSSGB on January 01, 2026, 07:19:10 AM Hello everyone,
I am currently doing reverse engineering work on BMW MG1 ECUs using SWFL files in IDA Pro. I understand that public SWFL/SWFK files extracted from vehicles do not contain ELF information, and that MG1 reverse engineering is therefore typically done manually (code → data → calibration). However, I would like to better understand what exists in theory versus what is accessible in practice during development: - Do ELF files or linker map files exist internally for BMW MG1 ECUs? - Are symbolized builds (or partially symbolized builds) used during MG1 development? - Are A2L + ELF combinations used internally for calibration and debugging? - Or is MG1 reverse engineering in practice entirely limited to SWFL files with manual memory mapping? I am not asking for files or downloads, only trying to understand what exists in OEM/internal environments versus what is publicly available. Any clarification or experience-based insight on this topic would be appreciated. Thanks. |
