Removed text is struck through; added text is highlighted.
Documented variant
MS4X associates MS41.1 with M52 OBDII. MS4X reference.
Software and definition coverage
The cited TunerPro catalogue identifies its MS41 definition as MS41.0; it does not establish an MS41.1 match. MS4X reference.
Record the actual software identification and definition provenance with this variant. The engine/emissions label selects the branch; it does not establish the addresses or complete coverage of a map pack.
Using the family guide
The MS41 memory reference and calibration map guide hold the common material. Keep any later worked calibration here tied to its original read, exact software, engine specification and measured result.
For a definition from another author, inspect its supported IDs, file basis, table dimensions and units. Compare several known tables before editing; do not treat a similar-looking table surface as proof of a software match.
Sources and scope
Original reference notes by Tuning Wiki, informed by the linked MS4X Wiki pages. MS4X Wiki contributors and the authors credited by each linked project remain the source authors. Sources checked 10 November 2026. Suggested validation steps and worked arithmetic are editorial guidance; they are not a tested calibration or a claim of hardware verification.
