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.

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 “MM3Stock.s2g” and for a Smarty Touch tuner it will be called “UDCStock.s2g”.

Place the SD card in your computer, locate this file and email it to robd@mm3tuning.com for your custom tuning.
