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

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. xdf to kp
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
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

bri3d/a2l2xdf: Convert ASAP2 A2L files to TunerPro XDF files
I assume you want to convert data from an XDF file (Microsoft/Revo ScaleR or similar eXternal Data Format) into KP (I’ll assume "KP" means a key-value pair format, “.kp” file, or a specific knowledge-product format). Because "KP" is ambiguous, I'll provide two concise, actionable paths: (A) convert XDF to plain key–value pairs (JSON) and (B) convert XDF to a generic "KP" CSV-style key|value format. If you meant a different KP format, say which one and I’ll adapt. | Metric | XDF (Source) | KP (Target)
Prerequisites (common):
A) Convert XDF → JSON (key–value pairs) using R (RevoScaleR)
library(RevoScaleR)
library(jsonlite)
xdf <- RxXdfData("input.xdf")
df <- rxImport(xdf) # imports whole dataset; for very large files use rxDataStep with rowSelection or chunking
kv_list <- apply(df, 1, function(row) as.list(row))
json <- toJSON(kv_list, pretty=TRUE, auto_unbox=TRUE)
write(json, file="output.json")
Notes:
rxDataStep(inData=xdf, outFile="temp.csv", overwrite=TRUE)
# then stream temp.csv to JSON in chunks
B) Convert XDF → simple KP (pipe-separated key|value per row) using R
library(RevoScaleR)
xdf <- RxXdfData("input.xdf")
df <- rxImport(xdf)
cols <- names(df)
kp_lines <- apply(df, 1, function(r) paste(paste0(cols,"=",r), collapse="|"))
writeLines(kp_lines, "output.kp")
Example output line: col1=42|col2=foo|col3=2026-04-10
Alternative: Python approach (if using xdfread)
from xdfread import XdfReader
import json
xr = XdfReader("input.xdf")
rows = [dict(r) for r in xr]
with open("output.json","w") as f:
json.dump(rows, f, indent=2)
If "KP" refers to a specific product or format (e.g., KeyPass, Knowledge Pro, KoboPocket, etc.), tell me which one and I’ll give exact conversion steps and sample code.
Converting XDF to KP: A Guide to ECU Mapping Formats In the world of automotive engine tuning, moving between different software environments often requires converting definition files. One of the most common technical requests is converting XDF (TunerPro) files to KP (WinOLS MapPack) files—or vice versa. Understanding the Formats
XDF (Extensible Data Format): The native definition format for TunerPro, a popular free tuning software. These files act as a "decoder ring," telling the software how to interpret raw binary data from an ECU into real-world values like spark advance or injection timing.
KP (MapPack): A proprietary template format used by WinOLS, a professional-grade ECU editing suite. KP files store map definitions, including their addresses and scaling factors within a binary file. Why Convert XDF to KP?
While TunerPro is highly accessible, many professional tuners prefer WinOLS for its advanced automated map-finding capabilities. Converting an XDF to a KP allows a tuner to bring existing community-sourced definitions from TunerPro into the more powerful WinOLS environment for deeper calibration work. How to Perform the Conversion
Direct conversion can be challenging because KP is a proprietary, often non-binary "blob" format that changes between WinOLS versions. Here are the primary methods used by the community:
Official WinOLS Plugins: The most reliable method is using the OLS526 (TunerPro XDF Importer) or OLS524 plugins for WinOLS. These allow users to directly import and export XDF files within the WinOLS interface.
Community Tools: Some developers have created standalone utilities like mapdump (bundled with ecuxplot), which can handle specific versions of KP to XDF conversion, though compatibility varies by version.
Manual Mapping: If automated tools fail, tuners often open both programs side-by-side. They manually copy the map addresses, rows, columns, and conversion formulas from the XDF Item Editor into a new WinOLS MapPack. Key Considerations KP Template File Format
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: Always validate your output KP file by loading
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
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
Converting (TunerPro ECU definition files) to (WinOLS Map Pack files) is a common task in automotive engine tuning to move map definitions between software platforms. Guide: Converting XDF to KP 1. Preparation & Tools
Before starting, ensure you have the following software installed: TunerPro RT : To view and verify your original : The target software for the A Map Conversion Tool
: While there is no "Save As" button for this, specialized converters like
(often used for the reverse) or scripts from communities like are standard. 2. Identify the Base Files
You cannot convert an XDF in isolation; it must be matched to a specific binary ( Binary File : The raw data from the ECU.
: The "index" that tells TunerPro where the maps (like ignition or fuel) are located in that specific binary. 3. Conversion Methods There are two primary ways to move your data: Method A: Manual Import (Most Reliable) Open your binary file in
or a text editor to see the addresses and dimensions of the maps. In WinOLS, use the "Insert New Map" Manually enter the Hex address Factor/Offset found in the XDF. Once all maps are entered, go to Project > Exporter > Map Pack (.kp) to save your work. Method B: Automated Scripting/Converters Locate a script or tool that reads the XML structure of an and outputs a text format. Verify the output
: Automated tools often struggle with "Factor" and "Offset" calculations (e.g., converting raw hex to Celsius or RPM). You must double-check these in WinOLS against the original TunerPro values. 4. Verification After importing the KP into WinOLS, verify the following: Map Alignment
: Ensure the map curves look "smooth" and not like random noise, which indicates a wrong starting address. Unit Scaling
: Ensure the values (boost, timing, etc.) make sense in real-world units.
