New TunerPro bin definition files (xdf) series for Aprilia 125 euro5 with ecu Magneti Marelli MIU G4 (also called 32M4G1 or MIU4).

Some of the supported motorcycles:

  • Aprilia SR125 GT (euro 5)
  • Aprilia SX125 (euro 5)
  • Aprilia Tuono 125 (euro 5)

You can tune the most important engine maps with our bin calibration files (called XDF): spark advance, fuel (lambda), torque, idle engine speed, rpm limiters, etc.

Knowledge, experience, calibration studies and bench tests are the starting point for the development of the above mentioned maps.

A free chiptuning 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.
