, 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?
Converting allows automotive calibrators to port engine control unit (ECU) definition files from TunerPro ( .xdf ) over to WinOLS ( .kp ), the industry-standard software for vehicle remapping. This critical process saves hours of manual calibration by transferring exact table addresses, conversion factors, and axis parameters between the two software ecosystems. 💡 The Core Concepts: Understanding the Formats
kv_list <- apply(df, 1, function(row) as.list(row)) json <- toJSON(kv_list, pretty=TRUE, auto_unbox=TRUE) write(json, file="output.json")
Directly converting an XDF to a KP file requires translating XML formatting into a structure that WinOLS can interpret. Because WinOLS does not natively import TunerPro .xdf files directly, tuners use a couple of primary workflows. Method 1: The CSV Intermediate Bridge (Most Reliable) xdf to kp
As the search results show, the most common approach is to ask for help on dedicated forums. Users with the OLS526 plugin will convert the file for others, often in exchange for access to other maps or a simple “thanks”.
Before starting the conversion, it is important to understand what these files actually do:
: Users on forums like NefMoto or Reddit's r/ECU_Tuning often assist with conversions if you provide both the .bin (binary) file and the corresponding XDF. Key Differences to Note XDF (TunerPro) KP (WinOLS) File Structure XML (Readable Text) Binary (Proprietary) Portability High; easy to edit with notepad Low; requires WinOLS to view/edit Capability Standard map definition Supports advanced subfolders and scripts , as TunerPro and WinOLS often handle raw
: Open WinOLS and load the corresponding raw project or binary ( .bin ) file matching your XDF definition.
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
[ TunerPro .XDF ] ──► ( Drag & Drop into WinOLS with OLS526 ) ──► [ Internal WinOLS Map ] ──► Export as .KP This critical process saves hours of manual calibration
For complex ECU definitions where manual entry is too time-consuming, professional tuning services offer conversion as a paid request.
Many users start with TunerPro because it is free or low-cost, accumulating a library of XDF files. As they progress to the more advanced features of WinOLS—such as superior visualization, checksum correction, and extensive database management—they need to bring their existing map definitions with them. How to Perform the Conversion
In 2012, the Hubble Space Telescope stared at a seemingly empty patch of sky for 23 days. The result? The eXtreme Deep Field (XDF) — a mind-shattering window 13.2 billion years back in time, revealing 5,500 galaxies in a speck of space smaller than a grain of sand. Silent. Ancient. Majestic.
If you have a specific map layout or file type you are trying to convert, let me know the (e.g., Bosch ME7, EDC16) or the vehicle platform you are working on, and I can give you more exact offset and scaling instructions! Share public link
