PAT Cummins XCAL / HEX to BIN Converter software interface, used for converting custom diesel tuning files.
Overview
Software: PAT Cummins XCAL/HEX -> BIN Converter v1.0 by Performance Auto Technologies.
Purpose: Converts Cummins XCAL and Intel HEX (.hex, .ihex) tune files into standard or software-compatible binary formats.
Output Options Visible: EFI Live BIN (CM24xx/CM2350B), HP Tuners BIN (CM24xx/CM2350B), Bench BIN, Raw Flat BIN, and Separate Segment Files. [1, 2]
1. File Format Conversion
Input Files: It reads original equipment manufacturer (OEM) Cummins calibration files, which are usually distributed in .XCAL or standard Intel HEX (.hex / .ihex) formats.
Output Files: It un-pads, structures, and compiles that text-based or XML data into raw, unencrypted binary (** .BIN**) files. [1, 2]
2. Tuning Software Compatibility
Factory .xcal files cannot be read directly by third-party editing tools. This software processes the raw bytes so the file can be opened, modified, and saved inside popular tuning platforms. The "OUTPUT MODE" options visible in the dropdown show dedicated configurations for: [1, 2]
EFILive BIN (specifically targeting heavy-duty modules like CM24xx and CM2350B)
HP Tuners BIN
Bench BIN (for direct-to-board flash tools like Flex, Kess, or Trasdata)
Raw Flat BIN [1]
3. File Padding & Data Structuring
Fill Byte Options: When converting structured code to a flat binary image, empty spaces must be padded out. The software allows you to choose a filler value (like 0xFF) to ensure the file maps perfectly to the flash memory size of the Engine Control Module (ECM). [1, 2]
Metadata Parsing: It displays crucial engine file fields, sizes, segment types, and start/end memory addresses so tuners know exactly what version of the software they are working with
