About ULP files
The .ULP extension represents a collision between two distinct technical worlds: automotive tuning and PCB design.
1. ECU Firmware (71% of files): Most frequently, a .ULP file is a Universal Language Package used in automotive ECU tuning. Internally, these are often formatted as Motorola S-Records - an ASCII text representation of binary data (Hex code). Tuners and mechanics typically encounter friction here because many modern flashing tools require raw binary (.BIN) or .HEX files, not the verbose S-Record text found in the .ulp container. You cannot simply rename these to .bin; they must be cryptographically converted to strip the ASCII headers and checksums to restore the raw machine code.
2. Eagle User Language Program: In the electronics industry, .ULP files are C-like scripts used by Autodesk Eagle (now part of Fusion 360) to automate board layout tasks. While these are plain text files, they are useless to non-engineers unless converted to .TXT for viewing in standard editors or .PDF for documentation and archiving.
3. Game Data: A minority of files may be data mods for Multi Theft Auto, a GTA modification framework.
Convert.Guru analyzes your ULP file, detects the exact format, and lets you read the text inside.
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 Calibration & PCB Scripting" 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 Calibration & PCB Scripting" category.
The ULP Converter Story
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.
