BMW E46 6-cylinder petrol ECU. OpenRemap identifies it (Siemens /
MS43 — e.g. program number 430069, Siemens part 5WK90027) and
verifies its checksums.

Identification: the literal MS43 family string + 5WK9 Siemens part
prefix at the exact 512 KB size gate (disambiguated from Simtec56, which
shares the 5WK9 prefix, by size). identify reports HIGH confidence.
Checksums: full coverage — boot / program / calibration CRC-16/ARC over descriptor tables, cracked from boot-code disassembly. The 32-bit monitor sums are runtime checks and are reported as unverified. See Checksums command docs.
