Revision 1: Siemens MS
Series index
Choose an ECU family below. Each family reference records its own memory and calibration context. Shared article listings identify the specific families they cover.
Reading definitions
Siemens terminology explains common words; Choosing ECU definition files describes the identification record to keep with a definition.
Sources
Curated reference notes. Applicability follows the cited sources; hardware testing by this wiki is not implied.
Revision 2: Siemens MS
MS family index
This branch sits within Siemens / Continental. Keep common methods here and hardware, memory layouts, software coverage and variant differences with their ECU pages.
| ECU family | Starting point |
|---|
| MS41 | M52 / M52 OBDII / US S52 subvariant references. |
| MS42 | M52TU; family memory layout and configuration. |
| MS43 | M54; driver demand, hardware changes and software packages. |
| MS45 | MS45.0 and MS45.1; fuel-mass strategy and separate sensor contexts. |
Shared guides
The shared guides state their covered families. Placement under MS does not imply applicability to every Siemens / Continental controller. MSS and Simos retain their own branches.
Reference vocabulary
Siemens terminology remains a generic reference. Choosing ECU definition files provides the cross-family provenance checklist. The words in a parameter name help locate a function; its software-specific definition establishes the meaning and units.
