New TunerPro XDF for Yamaha SR400 with ECU Denso.

With our XDF you can modify some engine parameters like fuel maps depending on throttle position and intake pressure, main spark advance maps divided by gear, axes (rpm, throttle, intake pressure), rpm limiters, lambda sensor deactivation.

Knowledge, experience, calibration studies and bench tests are the starting point for the development of the above mentioned bin definition files (xdf).

A free tuning software combined with competitive prices (50 euro) are the milestones of our philosophy.

Through the definition files, the remapping software TunerPro identifies the engine working parameters which allow to obtain the maximum power and torque without affecting the degree of reliability.

TunerPro is a binary files editor, not able to read and write the engine control unit. To do this, you need an external tool. We don’t provide information about these tools.


Price for each xdf: 50 euro.

Supported vehicles are available in the main motorcycles bin definition files area.
