PAT Incal/Xcal Tool — Cummins Incal Unpacker/Repacker, XCAL/CAL to BIN Converter & Incal Downloader

Description

PAT Incal/Xcal Tool

The all-in-one Cummins calibration toolkit from Performance Auto Technologies.
Extract, inspect, convert, fetch, and repack Cummins Incal / XCAL / CAL files from one fast,
modern, secure Windows application. Whether you’re pulling a calibration off the ESDN drive,
converting it for WinOLS, or packing an edited file back into a valid incal for INCAL/INSITE,
the PAT Incal/Xcal Tool does it in a few clicks.

—This tool is fully updateable to stay current with new fixes, features, and functions. Updates are free with genuine license from us or one of our resellers!—

Five tools in one

• Incal Extractor – Unpack the password-protected, AES-encrypted incal
  archives straight from your ESDN data folders. Browse by 3-character engine code or pick a
  file directly, view full calibration details, and extract single files or an entire engine
  family in one click (keep the original extension or save as .xcal / .cal).
• File Converter – Convert an extracted .xcal / .cal
  (Intel-HEX) calibration into a flat .bin image ready for tuning tools such as
  WinOLS. Choose the bin base and gap-fill byte; every record is checksum-verified and the
  address range, size, and record count are reported.
• File Fetcher – Search the PAT calibration server by engine code
  or ECM code, preview calibration details, and download with optional automatic
  extraction – even on machines without a mapped network drive.
• Repack Incal – Pack a modified .xcal back into a genuine
  incal that INCAL/INSITE accepts. Faithfully reproduces the original WinZip-AES (AE-1, AES-256)
  format and recomputes the archive integrity hash automatically. Includes an Intel-HEX checksum
  checker and one-click auto-correct for records broken during editing.
• ESDN Date – View and edit the INCAL dataset date shown in INSITE
  (e.g. “April 2026”), with an automatic backup before any change.

Calibration insight built in
