XDF Definition File for TunerPro
What do we do?
We create customized bin definition files (XDF) for free tuning software TunerPro which include the maps to manage engine and gearbox.
What are XDF definitions?

The bin definitions files, called XDF or templates or calibration files or bin definitions contain engine or gearbox maps that deciphers what each byte in the bin file stands for in the real world.
It tells the editing software TunerPro how to interpret each byte in the bin file (original or tuned file). XDF format is the native definition format used by TunerPro tuning software.
The definition basically says, in plain English, “the byte at location X in the bin file should be multiplied, divided or offset by W, Y, Z to come up with a real world number. TunerPro uses this entry to take the binary information and present it to you, the user, in a useful, understandable representation.
Please note: TunerPro is not able to read and write ecu, with it you can only modify the file read out from the engine control unit.
