Yes, Drag and drop the tunes into your "Custom" folder on the SD Card on your computer and then Put the SD Card into your mini max (make sure you eject the SD card before you remove it from your computer).
From the main menu on your mini maxx select install download, complete the key on/off cycle, this time from the install menu you’ll find that it has an option to install MCC, select the MCC option. Make sure your mini maxx is on the batt power setting on the power box and not on the ignition selection.
The next menu you’ll be prompted to export an MCC file, or download custom file, select download custom file.
Input your 16 digit MCC unlock code
You’ll now be prompted to select which files to install, if you have multiple options, select the ENG/ECM file first, followed by the TCM/Trans file second.
I should note you should update the firm ware in your Mini maxx before you upload the MCC files.
Hope this helps :thumbsup:
