The all-in-one calibration toolkit from Performance Auto Technologies.

Extract, inspect, convert, fetch, and repack Incal / XCAL / CAL files from one fast,

modern, secure Windows application. Whether you’re pulling a calibration off our incal server,

converting it for WinOLS, or packing an edited file back into a valid incal for INCAL/INSITE,

also has .ECFG/.E2M File downloaded, including many real uncommon ones like BKK and BHQ

Overlays can be purchased through the tool via credits and downloaded locally for use in calterm.

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 details built in

Select any file – packed or extracted – and the tool reads its embedded compatibility header

and shows the calibration version, module, part number, interface level, boot loader versions,

creation date, and more, so you always know exactly what you’re working with.
