VTune is a Windows-based easy-to-use VE table tuning tool tailored specifically for use with 2006 and later Delphi-equipped Harley-Davidson® motorcycles that are equipped with O2 sensors.

VTune requires use of a TTS MT7 calibration and a VTune DM3 data recording and combines the two generating a new MT7 calibration file with an optimized VE Table.
