High Performance Parts for American V-Twins Since 1958
The NEW ProTune II 2.5 software offers two levels for tuning your S&S VFI (Variable Fuel Injection) Modules, basic level for general tuning and advanced level for detailed tuning. The basic level ProTune II, is fairly simple, but has more capability then the original "EasyTune" software that was first supplied with VFI systems. The requirements of a specific tuning job and the tuner's level of skill should determine which level is used.

We have combined tune-files with their appropriate ECU code into one file to create what we have termed Box files. When utilizing the new Box files (calibration files with a .box extension), ProTune II version 2.4 or later must be used. Box files allow the user to load one file to their ECU, eliminating the need to manually match a tune-file with an ECU code

This ECU code and Tune Files for current ProStock motors.
Note
: The Tune Files must be used with this ECU code. The *.ec2 file is to be used with the original ProTune software.
This is a link the older TuneFiles and ECU code for customers that need to revert to these versions of software.
Note: These Tune Files must be used with the older versions of software contained in this Archive Section. Archived Tune Files will be periodically updated to work with the new ECU code
