Bosch ME7.5 · VAG 1.8T 20V

The whole calibration manual, as a searchable reference.

Sixty chapters, fourteen parts and eleven appendices covering the DAMOS-to-ECU cross-reference, firmware compatibility, and every calibration, diagnostic and hardware subsystem on the Infineon C167CR platform — with every address, offset and formula carried across from the source document verbatim.

PART I
Bosch Engineering Foundations

How Bosch names, stamps and packages a calibration. Project taxonomy, the EPK string, VAG and Bosch part-number grammars, hardware revisions, the SGML container, ASAP2 tags, and the deconstruction of four real master DAMOS files.

4 ch9,301 words11 tables
PART II
Compatibility, Memory Geometry & Fault Management

Which ECU will accept which donor file. Sibling clusters, hardware/firmware interoperability, KWP2000 timings, seed-key, flash mirroring, inline vs shared axes, and the DFPM fault-path tables.

3 ch4,261 words8 tables
PART III
Platform Conversion, EEPROM & Flash Integrity

Porting a longitudinal or A4 donor onto the 06A transverse. The ST 95040 / 95080 serial EEPROM page by page, immo defeat, the three-tier main-flash checksum hierarchy, and the complete 1024 KB flash topography with the real-time task call tree.
