- Make sure you have a charger on the truck with good batteries (clean all terminals etc.) or go buy a new battery if not. Make sure there are no aftermarket accessories on the truck or have their fuses pulled.
- Plug tuner into the truck. Next hook the tuner up to wireless internet (Wi-Fi) or turn on the hotspot on your cell phone and connect to that. The tuner will then update to the truck, this can take roughly 10 to 30 minutes. (If this update doesn't work, you will need to download the SCT update agent and update the tuner with it plugged into a computer) (LINKS BELOW)
Delete Custom Tunes are pre-loaded onto the tuner and will be labelled HEAVY TOW, LIGHT TOW, MPG/STREET, RACE & SOTF.
- Go to custom tuning, select one of the following off-road delete tunes to install: HEAVY TOW, LIGHT TOW, MPG/STREET, RACE & SOTF (Switch on the fly) ONLY install SOTF if you have installed the SOTF switch beforehand. Tuner will download onto the truck, once it is 100% complete you are good to go.
You can then do the tranny relearn if needed - For Tranny Relearn click HERE
