New / retained DATA CONFLICTS

DC-P19-001 — S50B30US power

• BMW North America historical feature: 240 hp.
• BMW Group Archive M3 Lightweight card: 243 hp / 178 kW.
• Decision: keep one regional engine revision with both source-native ratings; do not average or silently convert.

DC-P19-002 — M73B54 source presentation

• BMW Archive narrative: 326 hp.
• same page technical table: 240 kW / 327 bhp.
• Decision: same engine state, unit/presentation discrepancy flag.

DC-P19-003 — M62B44TU camshaft-control wording

• BMW Archive 540i Touring page describes variable control for intake and exhaust / “Double VANOS”.
• Decision: preserve exact primary-source claim as a source-wording flag and require an engine-training-document audit before canonical architecture wording is finalized.

DC-P19-004 — S52B32 US displacement / power

• BMW Group Archive M3 (E36), US model: 3152 cc / 243 hp / 178 kW @ 6000 rpm.
• BMW North America historical feature: 3201 cc / 240 hp.
• Decision: BMW Group Archive technical card is retained as the canonical specification row because it is a dedicated vehicle/archive card; the conflicting BMW NA historical figures remain attached as primary-source conflict metadata.

Quality gates

• No new row may infer a full engine suffix from displacement alone.
• U.S. M3 engines are separated from European S50B30/S50B32.
• Biodiesel is a separate technical revision because BMW changed seals/hoses for RME.
• TU states remain separate even when peak output is unchanged.

Still open for редакционная глава+

• definitive primary code sheet for M43TU and M44 full suffixes;
• primary full suffix for standard M70 5.0;
• dedicated M52 engine documentation for every market block-material and emissions variant; exact M52B20TU and M52B25TU suffixes are now primary-confirmed;
• S38B35 North America/Japan catalyst normalization from BMW primary documentation;
• 2000s M54/M56/M57/M47 and later N/S families.
