Extract text from Firmware and script files (ULP)
To convert ULP Scripts to another format, you need Autodesk EAGLE or other Developer software.
To convert other file formats to the "Calibration Data & Script" file type, you need software like Autodesk EAGLE or a similar tool.
The .ULP file extension primarily serves two distinct technical functions: as an ECU firmware/calibration data file (often encoded in the Motorola S-record format) for automotive tuning, or as an Autodesk EAGLE User Language Program script for PCB design automation. A smaller percentage of these files are used by the Multi Theft Auto game modification to store multiplayer server data.
Opening these files depends entirely on their origin. Automotive tuners use specialized software like WinOLS or ECM Titanium to interpret ECU data, while CAD engineers execute scripts directly within the EAGLE environment. Because scripts and S-records are often ASCII-based, text editors like Notepad++ can read the raw code.
Users often need to convert these files because they are tightly locked to their specific ecosystems. ECU files are highly specialized and often completely unreadable without an expensive subscription to proprietary tuning software. Similarly, EAGLE scripts are useless without the parent CAD engine, and MTA game files are strictly locked to the game server.
If you are modifying automotive firmware, you may need to convert the .ULP file to a standard BIN or HEX file to flash the control unit. EAGLE scripts are already plain text but can be safely renamed or converted to TXT or C for code review. Note that converting a binary game data file will almost always corrupt the player profile.
Because the .ULP format covers multiple proprietary, niche uses - from automotive data blocks to CAD automation tools - standard online converters consistently fail to process them. They lack the tools to parse S-records or C-like scripts. Just drag and drop your file to convert.guru to identify the format, view the internal hex or text content, and convert it when possible.
Convert.Guru analyzes your ULP file, detects the exact format, and lets you read the text inside.
Users also converted S19, CAL, TXT and MMF files.
If you want to convert ULP file to DWG, DXF, DGN, RVT, RFA, SKP, 3DM, STEP, IGES, SAT, X_T or X_B, you can use Autodesk EAGLE or similar software from the "ECU Firmware & CAD Script" category. In the File menu, look for Save As… or Export….
To convert SLDASM, DGN, PRT, IAM, X_B, CATPRODUCT, SLDPRT, RVT, ASM, DWG, CATPART or DXF files to ULP, try Autodesk EAGLE or another comparable tool in the "ECU Firmware & CAD Script" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ULP converter.
