MasterTune2-HD is a Windows-based ECM calibration development tool developed and designed specifically for use on all Delphi-equipped Harley-Davidson® motorcycles from 2001 through 2017.

MasterTune2-HD works with all TTS communications interfaces. Some features may not be supported on all communications interfaces.

Note that MasterTune2-HD licensing is associated with the programming interface. A communications interface can be licensed to program either one or two vehicles, and the communications interface will 'lock' to the vehicle the first time it is used for programming.

MasterTune2-HD includes the following key features:

  • Saves the original factory calibration automatically.
  • Easily restore the original factory calibration back into the ECM.
  • Preset limits to prevent adjusting values beyond reasonable settings.
  • Stores original and the last table saved edits so tuner can return to previous configuration.
  • Comparison functions quickly identify changed regions in tables.
  • 2-D and 3-D graphing of tables to help visualize tuning maps.
  • Ability to print table graphs and table values.
  • Supports tuning using wideband O2 sensors. Requires an analog (green) communications interface.

Some of the calibration adjustments include:

  • Spark Advance, front and rear
  • Knock Control
  • Volumetric Efficiency, front and rear
  • Rev Limit
  • AE/DE fueling
  • EITMS settings
  • Idle Speed
  • Start/Warmup fueling
  • Primary Gearing changes
  • Fuel Injector size
  • Engine Displacement
  • AFR/Lambda Target
  • NOTE: Not all features are available in all calibrations.
