vw polo marelli 4tv ecu tuning with tunerpro

New TunerPro bin calibration file (XDF) for VAG group with engine control unit Magneti Marelli IAW 4TV.

Supported cars:

  • Seat Cordoba (6L) 1.4L 16V
  • Seat Ibiza (6L) 1.4L 16V
  • Skoda Fabia (6Y) 1.4L 16V
  • Volkswagen Polo (9N) 1.4L 16V

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.
