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”…
Now Place the SD card in your computer using the included Micro-SD to USB adapter and open your email application (gmail, yahoo mail etc.) Using the “attach” button in your email (typically a paperclip icon):
- Navigate to the SD card
- Open the custom folder
- Open the stock folder
Now you will see the following file:
- For an MM3 Tuner will be called “STOCK.MM3”
- For a Smarty Touch tuner it will be called “UDCStock.s2g”.
(You will notice an incorrect date associated with the file; this is normal.)
Select “stock.mm3” or “UDCStock.s2g” to attach to your email and send the file to:
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.
