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.
