Exact package scope

MS4X’s cited package targets MS430069, E46, M54B30, EU4, left-hand drive. It documents a change from 1389 to 2778 mg/stroke load range and includes the 2048 kg/h MAF modification. It requires matching binary, XDF, ADX and patchlist files; a stock-load partial must not be mixed with the extended-load program. MS4X reference.

Treat the files as a set

Record the exact release and hash of each component. When a numerical representation changes, both editing and logging must interpret that representation consistently. A familiar table name or a 64 kB file size does not establish that consistency.

ComponentEvidence to preserve
Full program and calibrationPackage identity and original intended application.
Editor definitionSupported program, partial/full basis and version.
Logger definitionExtended-load interpretation and required logging feature/version.
PatchlistExact compatibility statement and modifications already included.

Evaluate the represented range

A useful validation record checks sensor range, internal load, table axes and resulting fuel/ignition behaviour together. Document whether the logger can show the relevant internal quantities without clipping. An increased numeric range does not by itself establish injector capacity, mechanical suitability or a correct intake model.

Use the shared MS42/MS43 load explanation for terminology. Keep results from this software package on this page with its exact scope rather than generalising them to another engine or ECU family. Obtain the files from the original source and retain its contributor credits and release notes.
