Executive Summary
What a factory DAMOS actually contains, and what this manual is for.
What a factory DAMOS actually contains, and what this manual is for.
In Bosch ME7.5 ECU reverse engineering, calibration definition files—commonly known as DAMOS files (ASAP2 standard .dam, .a2l, and .sgm data dictionaries)—are the definitive source of truth for memory layouts, axis descriptions, conversion formulas, and diagnostic fault paths. Unlike generic third-party definition files (such as basic community .xdf or .kp files which often only define 50–200 maps and frequently suffer from incorrect scaling or address drift), factory Bosch DAMOS files define 4,500 to over 5,200 unique engineering symbols, covering every control loop, internal RAM calculation variable, and diagnostic codeword.
However, tuning engineers frequently face the challenge of calibrating an ECU binary for which no direct, identically named .dam file is publicly available. Because Bosch developed firmware in modular generational codebases (such as the 21D, 22i, 23G, 24B, and 24D project families), a single engineering DAMOS can serve as an exact or near-exact donor for multiple vehicle part numbers, software revisions, and regional variants.
This document establishes the authoritative master cross-reference matrix mapping all known Bosch ME7.5 DAMOS files to their corresponding VAG ECU part numbers (specifically focusing on 06A906032LP, 06A906032PL, 06A906032SK, 06A906032HS, 06A906032CL, 06A906032DL, and related families across Volkswagen, Audi, and SEAT 1.8T platforms). It details:
- Bosch Engineering Project Taxonomy: Decoding project family codes (
21D,22i,23G,24B,24D), build suffix semantics (g,o,t,a), and software versioning. - Detailed Analysis of Primary Benchmark Calibrations: Direct file-level deconstruction of
06A906032LP,PL,SK,HS,CL,DL, andJJ. - Comprehensive DAMOS-to-ECU Compatibility Catalogue: Complete reference tables including VAG Part Number, Bosch Hardware Number (HW-TTNR), Bosch Software Number (SW-TTNR), Software Version, Vehicle Application, Engine Code, Power Output, Transmission, and Exact Paired DAMOS.
- Cross-Flashing & Calibration Donor Hierarchy: Rules for porting definitions, identifying binary relocations, and addressing inline vs. shared axis geometry without offset errors.
