Revision 1: MSS52 definition coverage

Supported source context

The repository lists D409 and D444 software and describes its XDF as incomplete. The Siemens MSS52 hub records the complete identifiers.

Matching workflow

  1. Read the ECU's complete identification.
  2. Match it against the repository's software, program and tune identifiers.
  3. Retain the XDF revision with the original image.
  4. Read item descriptions and verify units and data layout before using a parameter.

Download the definition from its original repository, retaining its author credit and MIT licence.

Sources

Curated reference notes. Applicability follows the cited sources; hardware testing by this wiki is not implied.

Revision 2: MSS52 definition coverage

Exact software match

The MSS52 hub records all README software, ZB, type, program and tune IDs. Retain those identifiers with the read and the XDF commit a04c0d24fe63. The author describes the file as incomplete and evolving. MSS52 project and software coverage.

What is present at this commit

A structural inventory finds 206 constants, 59 functions, 87 tables, 26 flags and 23 patches. These are definition-entry counts; alternative displays, axis entries and bit views share underlying data. They are not a count of independent engine functions or a measure of complete coverage. MSS52 XDF.

Preserve the author’s qualifiers, including [TESTING], [??] and [INCORRECT]. A descriptive English title is a starting point for investigation. Keep the original BMW symbol and the source comment beside any improved interpretation.

File-relative labels and orientation

The header’s editing region is 32 KiB. The XDF labels checksum fields at 0x3FFC as master and 0x7FFC as slave. These are the labels in this definition, not a verified physical memory or restore specification. MSS52 XDF.

Check the actual read format before applying offsets. MSS54’s extraction script documents a different controller-specific arrangement; matching partial-file sizes do not establish a common segment order or checksum method.

Practical matching record

  1. Read and preserve the complete ECU identification.
  2. Match the software record and establish the binary’s address basis.
  3. Retain the original XDF and its licence with its author credit.
  4. Verify several known items, axes and conversions before evaluating an edit.
  5. Record confidence, changes and measured results using the shared validation guide.
