This is a curated definition-file package for calibrators working with heavy-duty and industrial ECU binaries. It combines A2L descriptions and WinOLS KP map packs for several engine-controller families, giving an editor meaningful labels, axes and addresses instead of an unstructured hexadecimal dump.
The files are reference definitions rather than ready-made tuned binaries. A definition must match the exact software number and memory layout of the original read before any map is trusted or changed.

What this resource is for#
Use the package to identify calibration areas, compare known definitions with an original read and accelerate project setup in WinOLS or another editor that supports the supplied formats. It is especially useful when a binary contains hundreds of candidate tables and the ECU software family is already known.Confirmed functions#
- A2L definitions for CCP/XCP-style calibration descriptions where supplied
- WinOLS KP map packs with named maps and axis information
- Coverage folders organized by manufacturer or controller family
- Reference material for comparison and map discovery; no automatic flash or checksum operation
Supported controllers, files and vehicles#
- Cummins CM1881, CM2200 and CM2350 definition material
- Detroit MCM families including multiple MCM calibration generations
- CAT 7CZ, Duramax L5D and Ford truck map packs
- Navistar Bosch EDC17CV42 and related definitions
- PACCAR/DAF, Peterbilt, New Holland, Volvo/Mack and Freightliner-oriented files
- Exact compatibility is controlled by software number and binary structure, not only by truck make or engine name
Package contents#
- Twenty-eight primary definition files organized in manufacturer folders
- A mixture of A2L, KP and one OLS-associated definition
- One embedded Navistar definition archive was opened, tested and extracted during audit; it is not an unchecked link wrapper
System and interface requirements#
- Windows workstation with WinOLS or another compatible calibration editor
- Original ECU read with a verified checksum and known hardware/software identifiers
- Enough free space for working copies and comparison projects; the definition package itself is modest in size
- No vehicle interface is required merely to inspect definitions, but a suitable programmer is required to read or write an ECU
Recommended workshop workflow#
- Record the ECU hardware number, software number and read method before opening the project
- Create a read-only backup of the original binary and import only the definition most closely matching that identity
- Validate several known maps, axes and limit values before accepting the definition as a match
- Make changes in a separate project, correct checksums with an appropriate method and compare the output against the untouched original
Compatibility limits and responsible use#
- A map pack for a similar engine is not proof of compatibility
- Addresses can shift between software revisions even when the ECU hardware family is unchanged
- The package does not provide an automatic tuning strategy, emissions solution or safe torque target
- Never write a file solely because WinOLS accepted the definition without errors
Troubleshooting#
- If values or axes look implausible, stop and re-check byte order, file size and software identity
- If a KP imports with missing maps, verify that the project binary starts at the expected address
- For duplicate-looking definitions, compare their software identifiers and hashes rather than choosing by filename alone
