ECU Relationship Intelligence

Engineering workspace for BMW software traceability. Map the complete PSdZData dependency graph — 1,715+ ECU relationships, 2.2M logistic references, 21 series — indexed in real time.

SGBM Detail — versions, ECU nodes, I-Stufen

Software Lineage — trace versions, ECU nodes and I-Step presence

Relationship Graph — interactive node visualization

Relationship Graph — force-directed visualization of SGBM dependencies

Software Lineage

Search any SGBM ID → see all versions, ECU nodes, I-Step levels, logistic parts, conditions and related components.

I-Step Changes

Compare what changed between two BMW integration levels — which SWFLs, BTLDs and CAFDs were updated or added.

ECU Relationships

Browse every ECU by name/address, see its SWFL/BTLD/SWFK dependencies and usage conditions (SA, series, market gates).

Relationship Graph

Interactive force-directed graph — click any node to drill into its dependency cluster (SWFL→SWFK→BTLD→HWEL).

ECU Groups & Fault Codes

SGBD families (g_mmi, d_0012…), variants per group, and the full fault-code inventory per ECU variant.

Mapping Impact

249,000+ logistics references — see which TYPE keys, vehicle variants and production contexts receive each software component.

Per-app license or Enthusiast subscription required. View plans →

Engineering workspace: trace software lineage, compare I-Step changes, and validate ECU relationships before coding or programming decisions.

BRV:

Engineering Overview

Select a BRV (vehicle series) from the top-right dropdown to compare relationship data, ECU coverage, I-Step changes, and mapping impact by series.

Start with Software Lineage to trace SGBM/SWE families, then move into I-Step Changes and Relationship Graph for deeper technical validation.

How it Works

Interactive graph visualization of BMW ECU software relationships. See SGBM/SWE lineage chains, I-Step deltas, and cross-ECU dependencies. Understand which ECUs are affected when firmware changes — essential for flash planning, update impact assessment, and diagnostic confidence.

Requirements & How to Use

Select a vehicle series (BRV) to load the ECU relationship graph

Explore nodes — click any ECU to see its software lineage (SGBM → SWE chain) and version history

Compare I-Steps to see exactly what changed between firmware versions across all ECUs

Coverage

Full SGBM/SWE lineage, I-Step delta analysis, cross-ECU dependency mapping, flash impact visualization

Access

Per-app subscription. The only tool that shows software relationships across the entire vehicle.
