moto guzzi v7 marelli miu 38m3g

New TunerPro bin definition files (xdf) series for Moto Guzzi with ecu Magneti Marelli MIU M3G (also called 38M3G or 38M3G3).

Some of the supported motorcycles:

  • Moto Guzzi V7 750
  • Moto Guzzi V9 850

Available the most relevant engine maps like main spark advance, spark advance corrections, main fuel (lambda), fuel corrections, 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 (60 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.
