What are TunerPro XDF definitions?

Bin definition files, commonly referred to as XDF files, templates, or calibration files, contain structured metadata that map addresses within a binary (BIN) file to real-world parameters used by the engine or transmission control units.

These definitions provide TunerPro, a tuning and calibration software, with the necessary information to interpret raw binary data. Each entry within the XDF specifies how to decode a particular memory address: it defines the data type (e.g., 8-bit, 16-bit), address location, byte order, and the transformation formula (e.g., scaling factors, offsets, or conversion equations) required to convert binary values into human-readable engineering units.

The XDF format is native to TunerPro and enables it to render raw binary data as structured, labeled tables, maps, or scalar values. For example, an XDF entry may indicate that the byte at a specific memory location represents ignition timing and must be multiplied by 0.25 to yield a value in degrees.

Through these definitions, TunerPro can accurately visualize and allow modification of ECU or TCU parameters without requiring direct interpretation of hexadecimal data by the user.
