So for the Auto Off above that the wife is concerned about...
3 Things.
1) Remote Start - If it was remote started, 15 per remote start is the default factory setting, with a max of 30 minutes regardless of how many times you do it. So if your remote start is set at 5 minutes, you can extend it 6 times, to get to 30. This can be done via remote, or app. After the 30 is exceeded, you have to start it with key within range via button or ignition.
2) Idle Limit - Mine set at 60 minutes, but can't remember if it was stock set to that, or changed via FORSCAN. Vehicle shuts off after that amount of time idling. To reset that timer, place in drive or reverse for a sec and that clock starts again. You can also turn it off in settings per start up. Not sure if FORSCAN can turn it completely off, but pretty sure that is a yes.
3) Auto Start/Stop - Driving, come to a stop, engine turns off. Button can turn it off per start cycle. Sport Mode also turns it off. The AutoStopEliminator above makes the button setting hold across startups. It is the correct way to do it. Doing it in FORSCAN isn't really turning it off. It is turning off Battery Charge Management, which causes the battery to be charged at full voltage all the time(Not good). With that off the vehicle does not Auto Stop because it does not know the status of the battery there fore it won't turn it off for fear of not being able to start back up.
