The Ultimate Companion Tool for NCS Expert. Parse, Translate, and Edit BMW Coding Files with Ease.
NCS Dummy is a legendary and essential utility for anyone performing coding on BMW E-Series vehicles with NCS Expert. It serves as a powerful "translator" and safety net, taking the cryptic, text-based trace files from NCS Expert and presenting them in a clear, human-readable graphical interface.
What Problem Does This Tool Solve?
Coding with NCS Expert requires editing `.TRC` and `.MAN` files, which contain hundreds of German abbreviations and hexadecimal values. Manually editing these files is slow, confusing, and carries a high risk of making a syntax error that could cause issues with an ECU.
NCS Dummy completely eliminates this risk. It parses the trace files and displays every function alongside all its possible options, often with English translations. This allows you to simply check boxes or select from a list to enable or disable features, instead of editing text by hand.
Key Features
- Trace File Parsing: Intelligently reads and interprets `FSW_PSW.TRC`, `.MAN`, and `Nettodata` trace files.
- Module Function Browser: Provides a complete list of all functions and parameters available in any given ECU module.
- Translation Database: Includes a massive database of translations for German coding parameters into English, making it easy to understand what each function does.
- Safe Editing: Allows you to modify coding data without the risk of creating a syntax error. The tool builds the `.MAN` file correctly for you.
- Checksum Correction: Includes functionality to update checksums in DATEN and NFS files, which is crucial for advanced modifications.
- DATEN File Disassembly: Advanced functions for disassembling and analyzing the raw `.DAT` files from the SP-Daten.
- Trace Comparison: Easily compare two different trace files to see the differences in coding between vehicles or modules.
Initial Setup
- For full functionality, you must point NCS Dummy to your NCS Expert DATEN folder.
- Go to the "Options" tab in NCS Dummy.
- In the field "Path to NCS Expert DATEN folder," browse and select your `C:\NCSEXPER\DATEN\` folder.
System Requirements & Testing
- Operating System: This is a lightweight tool that works on all versions of Windows. It has been fully tested and confirmed to be stable on Windows 10 LTSC 2019.
- Required Software: A working installation of BMW Standard Tools (specifically NCS-Expert) and the corresponding SP-Daten files.
