Tuning strategy


  • The tuning system focuses on Harley-Davidson engines equipped with DELPHI EFI (diagnostic communication J1850 or CAN)
  • The tuning system is based on diagnostic system DIAG4BIKE.
  • DIAG4BIKE is the professional diagnostic tool for Harley-Davidson Motorcycles. The tuning software DIAG4TUNE is included in the diagnostic software from Version 12. To tune an individual motorcycle a TUNING DONGLE (or EASY TUNING DONGLE) must be purchased that can be used for that specific motorcycle. It is recommended to use last version of DIAG4BIKE software for diagnostic or tuning.
  • The tuning process does not require the installation of additional component(s) or any motorcycle harness modification. Tuning is based on the modification of EFI Calibrations (software modification) exclusively via the diagnostic connector.
  • The first step in Tuning is storage of the original EFI Calibration. The tuning operator can restore the original EFI Calibration at any time during tuning process (stock calibration).
  • The tuning process is used to optimize Fuel Maps in case of any changes to the configuration of engine components or accessories (exhaust or/and intake system etc.) .


AT531 4094 Advanced tuning (hardware key)

1. Advanced tuning


  • Map flashing from database.
  • By this method of the tuning is possible to use full range of DIAG4TUNE functions.
  • The method provides ability to use an embedded database of calibrations.
  • These calibrations (maps) are pre-set for several configurations of exhaust and intake components (openexhaust, intake and combinations).
  • Advanced tuning method provides important improvement of engine functions.
  • The best engine efficiency is possible to rich only by using PROFESSIONAL TUNING method.

2. Professional tuning


  • Engine fuel maps optimization
  • By this method of the tuning is possible to use full range of DIAG4TUNE functions.
  • The key function is here Volumetric efficiency map measurement under load. It means real VE maps measurement of each engine configuration.
  • VE map measurement can be done onan appropriate Roller Station, good example is SMART POWER BENCH, or during Road Test on the street.
  • Professional tuning method provides the best bike tuning for each special engine
    • maximal efficiency
    • torque
    • power
