MM3 TUNER: How to get the Stock File

NOTICE: These articles are provided for 5-9diesel.com customers but are available to the public as a courtesy. 5-9 Diesel LLC is an authorized seller of the MM3 Tuning Platform and is a separate company from MM3 PowerMM3Power.com is the tech support and warranty service provider for the MM3 Tuning platform.

The steps below will show you how to get the Stock File for your MM3 Tuner, Smarty Touch or RaceMe Ultra Tuner. This allows your custom tuner to write tunes that can be flashed to your truck.

This process WILL NOT alter your truck in any way, it will operate normally afterward.  Also take note that the files mm3.mmu and mm3.sgn are not the stock files!  Please follow the directions carefully.

From any gauge screen, tap anywhere on the screen…

Press “Main Menu”…

Then press the “ECM” button…

Press the next “ECM” button…

Press “Get Stock File For Truck”…

This will place a file on the SD card in the custom/stock folder. The file for an MM3 Tuner will be called “STOCK.MM3” and for a Smarty Touch tuner it will be called “UDCStock.s2g”.  You will notice an incorrect date associated with the file; this is normal.

NOTE: There are multiple files located on the SD card, any files other than the ones named above ARE NOT the “stock” file.  Sending anything other than “stock.mm3” or “UDCStock.s2g” will DELAY delivery of your tunes.

Place the SD card in your computer, locate this file and email it to robd@5-9diesel.com for your custom tuning.
