sym maxsim 508 ecu tuning m4c

New TunerPro bin calibration file (XDF) for Kymco and Sym with engine control unit Continental M4C.

Some of the supported bikes:

  • Kymco AK550
  • Sym Maxsim TL508
  • Kymco Downtown 350
  • Kymco Agility 350
  • Kymco DTX 360 350

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 (70 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.
