logo tondo ita oldskulltuning

We are a team of specialists in the tuning world, having many years of expertise in the automotive field about the development of ECU (engine control unit) and TCU (transmission control unit) calibrations for all vehicle types: cars, bikes, trucks, tractors, boats and special vehicles.

Aim of this project is to offer TunerPro definitions files (XDF), applying an affordable cost and using a FREE mapping software, to both professional and beginner tuners.

Please note: TunerPro is a binary files editor. It is not able to read and write ecu, it can only be used to modify the file read out from the engine control unit.

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.

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.
