3) Navigate to the location where you saved your tune file click your tune file then click Open. 

4) The writing process will take about 10 minutes.

5) Once it's done flashing, you will see "Flash complete".  Click Cable > Disconnect then remove the Commander, reconnect any factory cables you may have disconnected and take the truck for a drive!

4) If it doesn’t hold power at any throttle position repeat the process on the previous throttle position again

5) Once complete, plug the throttle valve back in if you are running a single-tune file on a 2022 ECM.  If you are running SOTF on a 2020-2021 ECM you can proceed to section G

Section G

1) Find a suitable location to mount the switch inside the cabin

2) Route the wires through the rubber grommet on the driver's side firewall into the engine bay

4) Insert the SOTF wires into the provided CAC connector (the orientation of the wires does not matter)

5) Unplug the CAC sensor and connect the SOTF connector to the factory CAC harness

6) Unplug the Throttle Valve sensor and tape the connector out of the way of any moving parts. 

The most common error is getting an error stating you don't have enough credits, this can happen with the ECM tune, TCM tune, or both and the reason is almost never a credit issue it's an issue with your internet connection or software.  You must have a solid internet connection and be on the latest software.  If you get a credit error, close the software, reopen it and look for an update prompt.  If you can, use a wired internet connection.
