In the world of automotive tuning, "XDF" and "KP" (WinOLS Mappack) are the two most common languages used to describe how to read an engine's brain. The Core Difference XDF is the open-source map definition format for TunerPro.

KP (WinOLS Mappack) is the proprietary professional standard for WinOLS. 🛠️ The Conversion Story

Converting an XDF to a KP (or vice versa) is like translating a complex blueprint between two different dialects of engineering. 1. Identifying the Goal

Why convert to KP? Most professional tuners use WinOLS. If you have an community-made XDF for a niche ECU, you’ll need to convert it to a KP to use the advanced diagnostic features of WinOLS.

Why convert to XDF? If you want to use the free, open-source TunerPro tool to edit your engine maps. 2. Finding Map Offsets Every ECU "Bin" (binary) file is unique.

The "Useful Story" of conversion usually involves finding the offset.

Even if you have the right map names, they won't work if they point to the wrong address in the memory. 3. Using Conversion Tools

Manual Entry: Most experienced tuners manually re-create maps in WinOLS by looking at the addresses in the XDF.

Scripts: Specialized scripts like a2l2xdf or custom Python tools help automate the extraction of map names and addresses.

ME7Tuner: For older Bosch ECUs, tools like ME7Tuner can parse KP files to help auto-select the right XDF definitions.

💡 Pro-Tip: Always verify your Checksums. Even a perfect map conversion can brick an ECU if the file's internal security signature isn't updated after editing.

To help you find the right files or tools, could you tell me: What car/engine model are you working on? Which ECU does it use (e.g., Bosch ME7.5, Siemens MS43)?

bri3d/a2l2xdf: Convert ASAP2 A2L files to TunerPro XDF files

To develop proper content for converting .xdf (TunerPro Definition) files to .kp (WinOLS MapPack) files, you are essentially translating map definitions between two different tuning software environments.  1. Understanding the Formats 

XDF (eXtended Definition File): An XML-based or binary definition file used by TunerPro. It maps out the addresses and conversion factors for parameters (fuel, spark, boost) within an ECU's binary (.bin) file.

KP (MapPack): A proprietary file format used by WinOLS. It contains the map definitions, including names, addresses, and scaling, for a specific project.  2. Recommended Conversion Methods 

Direct conversion is difficult because WinOLS uses a closed, proprietary binary format for .kp files. Most professionals use one of the following "bridge" methods: 

WinOLS OLS526 Plug-in (Official): This is the "proper" way. The TunerPro XDF Importer for WinOLS (OLS526) allows you to import .xdf files directly into a WinOLS project, which can then be saved or exported as a .kp file.

Manual Entry (Reliable): Since .xdf files are essentially structured data, you can open the .xdf in TunerPro and manually copy the address, conversion factors (offset/scalar), and axes into a new map in WinOLS.

A2L as an Intermediate: If you have an automated tool that converts .xdf to .a2l (ASAP2), WinOLS can import the .a2l and then export it as a .kp.  3. Critical Content to Include 

When preparing the content for the conversion, ensure the following metadata is synchronized between both formats:  Address: The exact hex location of the map in the binary. Data Type: 8-bit, 16-bit (HiLo/LoHi), or 32-bit.

Factor & Offset: How the raw hex value is converted into human-readable units (e.g., RPM, Degrees, Pressure).

Axes Definitions: Ensure the X and Y axis addresses and lengths (number of columns/rows) are correctly mapped, as WinOLS handles axis identification differently than TunerPro.  4. Technical Resources

Converting (TunerPro) files to (WinOLS Map Pack) files is a common challenge in ECU tuning, as there is no single "one-click" official tool to handle the transition between these two proprietary formats. Conversion Approaches is an XML-based format used by TunerPro and

is a binary format for WinOLS, you typically have to use community-developed scripts or manual methods: Microsoft Support Manual Porting (Reliable)

: If you only have a few maps to transfer, it is often faster to open both programs side-by-side. You can right-click parameters in TunerPro to "Edit Parameter in XDF," copy the hex address, and manually define a new map at that same address in WinOLS. Community Scripts : Some tuners use various versions of a tool called (available in

formats) to extract map data, though it often requires command-line knowledge. : For specific ME7 ECU platforms, tools like ME7Tuner on GitHub can parse KP files and help match them to XDF definitions. Intermediate Formats : A more common path is converting XDF data into a file or an

file first, as these are more widely supported as import/export formats across different tuning suites. Common Pitfalls

In the context of automotive engine tuning, (TunerPro Definition) and

(WinOLS Map Pack) files are the primary formats used to define the location and scaling of maps within an Engine Control Unit (ECU) binary file. 1. Core Differences & Use Cases XDF (TunerPro):

The primary "source of truth" for many DIY tuners. It provides full coverage for map definitions, axes, dimensions, and scaling factors. KP (WinOLS):

Typically used as an address cross-reference aid. In "hint mode," it may only extract name and address pairs without full parsing of axes or scaling. 2. Conversion and Cross-Referencing

While there is no single "one-click" official tool to convert between them, tuners use specific software to bridge the gap: ME7Tuner / MxT:

This tool can parse KP files to extract map names and addresses. When you open a map dialog, it can auto-pre-select

an XDF definition if the binary address matches the KP address, marking it with a "KP badge" for verification. Universal Patcher: Some users import XDF files into Universal Patcher

to create patches, though this can sometimes result in parameter errors if the formatting isn't perfect. Manual Matching:

Many tuners use both simultaneously—using the KP file to locate addresses in WinOLS and then manually creating or updating definitions in a TunerPro XDF for final editing. 3. Accessing Definition Files Tuning Platforms: Providers like MHD Tuning often release maps with both original .bin files and matching XDF/KP files for user editing. Community Groups:

Specialized Facebook groups (e.g., for BMW N54 or Audi 1.8T) frequently share specific XDF files (like the

The conversion of (TunerPro) to (WinOLS MapPack) is a common but complex task in ECU tuning, as it involves moving from an open XML-based format to a proprietary binary format. Direct Conversion Overview

There is no "one-click" native tool to convert an XDF directly into a KP file due to the proprietary nature of EVC WinOLS. However, several workflows allow you to bridge the gap: CSV Intermediate Method : Some users export map data from TunerPro to

, which can then be imported into WinOLS. While not a direct KP generation, it allows you to recreate the maps in the WinOLS environment. Manual Mapping

: The most reliable (though tedious) method is to open the XDF in a text editor to view the hexadecimal addresses and scaling, then manually create the entries in WinOLS. Third-Party Scripts : Community-developed scripts (often found on forums like ECU Connections

) occasionally surface, but they are often specific to certain ECU types or software versions. Key Format Differences XDF (TunerPro) KP (WinOLS MapPack) Human-readable XML Proprietary binary Flexibility Highly extensible and portable Restricted to WinOLS users Complexity Simple map definitions Advanced features (e.g., offsets, sub-folders) Recommendations for Users Use WinOLS Import : Check if your version of WinOLS supports importing

files, as these are more standardized and easier to find or convert than XDFs. Forum Assistance : If you have a specific XDF, community members on ECU Connections

often provide conversion services or "MapPacks" that match common TunerPro definitions. Verify Scaling

: When moving between these formats, always double-check the scaling factors

, as TunerPro and WinOLS often handle raw data math differently. specific MapPack for an ECU model, or are you looking for a python script to parse XDF data?

bri3d/a2l2xdf: Convert ASAP2 A2L files to TunerPro XDF files

In the context of automotive ECU tuning, XDF (TunerPro) and KP (WinOLS MapPack) are definition files used to map out parameters in a binary file. Converting from XDF to KP is often desired because WinOLS offers more advanced 3D visualization and analysis tools than TunerPro.

However, there is no single "one-click" feature or official tool to perform this conversion directly. Instead, the process generally involves manual mapping or the use of community-built tools: Options for Converting XDF to KP

The transition from represents a technical bridge between two of the most prominent environments in the automotive ECU (Engine Control Unit) tuning world:

. While both file types serve the same purpose—mapping the location and scaling of engine parameters within a binary file—they exist as two distinct languages of data definition. The Purpose of Map Definitions

To understand the conversion, one must first understand what these files do. An ECU's "binary" file is a long string of hex code that is unintelligible to the human eye. XDF (External Definition File): Used by the freeware

, these files define where tables for ignition, fueling, and boost are located and how to convert raw hex values into real-world units like degrees or PSI. KP (Map Pack): These are proprietary definition files for

, the industry-standard software used by professional tuners. The Technical Challenge

Converting "XDF to KP" is essentially the process of migrating a community-developed map into a professional workspace. The challenge lies in the formatting: Open vs. Proprietary:

XDF is an open XML-based format, making it relatively easy to read. In contrast, KP is a proprietary binary format created by EVC (the makers of WinOLS), which is not officially documented for external use. Scaling and Math:

A successful conversion requires more than just moving addresses; the mathematical formulas used to "translate" the data must be identical. If the XDF uses a specific offset that the KP doesn't account for, the tuner may end up seeing incorrect data, which can lead to engine failure during a live tune. Methods of Conversion

Because of the proprietary nature of KP files, there is no "official" one-click button to turn an XDF into a KP. Users typically rely on three methods: Manual Transcription:

The most common method involves opening both programs side-by-side. The tuner looks at the address and conversion factors in TunerPro and manually creates a new "map" in WinOLS. Community Tools: Specialized scripts, such as those found on forums like PCMhacking

, attempt to parse XDF data into formats that WinOLS can import, such as CSV or A2L. Intermediate Formats:

Often, users convert XDF to a CSV first, as WinOLS has robust tools for importing map lists from structured spreadsheet data. Conclusion

The demand for XDF to KP conversion highlights the collaborative nature of the tuning community. While TunerPro (XDF) is often the starting point for enthusiasts and hobbyists due to its low cost, many eventually graduate to the advanced features of WinOLS (KP). Bridging these two formats allows for the preservation of collective knowledge, ensuring that hard-won discoveries about engine logic remain accessible as tuners move toward professional-grade tools. software tools that can help automate this conversion? XDF to .kp or a2l ? - NefMoto

XDF is an open-standard, eXtensible Data Format designed to facilitate data exchange and flexibility across different applications and systems. It's used across various industries for its ability to handle complex data structures and facilitate interoperability.

In the field of automotive ECU tuning and calibration, XDF (ECU Definition Format) and KP represent two different approaches to data interpretation. The process of converting XDF to KP typically refers to translating calibration definitions created in TunerPro (a popular generic OBDI/II tuning software) into the native Hyundai/Kia .kp file format used by proprietary dealer tools (such as GDS or KDS) or specific chip-tuning suites.

This write-up details the structural differences between these formats, the necessity for conversion, and the technical methodology for achieving a successful translation.

As of 2025, the Open Formula Data Alliance (OFDA) is working on a unified XDF-KP bridge specification. This will embed a lightweight knockout channel directly inside a telemetry XDF file, eliminating conversion entirely. Until then, the methods described above remain the gold standard.

Furthermore, AI-based conversion tools are emerging. For example, neural networks can now learn the mapping between an XDF parameter (e.g., steering angle) and a complex knockout shape (e.g., a tire skid mark mask) without explicit thresholding. Tools like MaskMagic AI offer a "Data-to-Knockout" module trained on motorsport datasets.

Best for: Large organizations with diverse geospatial data.

FME by Safe Software has a reader for XDF (especially variants used in simulation). FME Workbench allows a visual drag-and-drop transformation from XDF to KML, including complex schema mapping. It is expensive but the most reliable for mission-critical conversions.
