What is the best way to extend idle time? I have 2017 lariat w factory settings. For example if I am in a restaurant and want to leave the heat or air on for a pet.

 

all i can seem to get is a half an hour idle time by remote starting and doing it twice. anyone else able to get an extended idle time somehow?

 

Interested in this also. I get like ten minutes.

 

Remote start is limited to 15 minutes times two and you can adjust in the dash if you have a lariat, it's in the remote start settings. but if you leave it running and lock it, it is limited as well. So you would have to restart it. I haven't checked the Forscan thread but perhaps there is a way to extend to an hour in Forscan? You may also see if your dealer can extend with the IDS system by programming it.

 

On my Platinum, I can go into settings/advanced vehicle settings and uncheck auto engine off and the truck will idle indefinitely if it has been started with the start button (not remote start). However, this has to be unchecked after each restart, as it always defaults to the auto engine off setting upon restart.

 

berndV, is that a sync3 system? i would take that over nothing at all.

 

Unfortunately there is not long term setting to have it say idling.
You just need to go to in Advance settings EVERY time you want it to stay running per ignition cycle

 

My 6.2 gasser has no limiter at all. I just idled it in a parking lot two days ago for over three hours. It was -10° and I was waiting with my daughter for AAA to pick up her car with a flatbed. It was actually worrying me, so I used Forscan lite to monitor oil pressure, temps, etc. All totally cool, no deviation or oil starvation, overheating, or anything else.

 

I am very glad I found this thread before I killed my dog. I would leave her in my idling 6.0 powerstroke all the time with the AC blasting in the summer. If the AC turns off when it's 110f out, the dog is dead. Interior temps can push 180F.

This truley upsets me, because I had no idea. Frigging enviormentalists.

 

Are you using the remote start to let it idle or just leaving the truck run locking the door with the key fob inside the truck? My XLT will and has run all day with the key in the ignition. I can lock the door with the keypad if I want to and unlock it the the keypad when I get back. Some days my truck will sit and idle for 8 hours or more because it is my work truck and is also my office. The remote start will only allow it to idle for 15 minutes before it shuts off.

 

I damn near killed my cow dog, left her in Penske truck with A/C on full blast while eating lunch, was a 100* day, went outside and truck was shut off with fan blowing hot air, still pisses me off to this day, truck auto shut offs after 12min.

Are you guys saying the truck shuts off even with keys in it running? That cannot possibly be the case, you have to be talking about remote starting.

 

My work truck 6.2 idles 10+hrs a day in 110* heat with a/c on high, all day everyday, you have NOTHING to worry about.

 

With the truck running, started without remote, or started by remote start and now running as you have pushed the start button, then you turn off Auto Stop in advanced settings in the dash. You will get the double honk when you leave and lock the truck. This is why when you open the door you get the warning the truck is running. That's when I do the auto stop off if I am leaving it running. For the sake of occupants, I would check this out and test. But this will work on a one time basis.

The double honks is meant to warn you your leaving the vehicle running so it's not in a garage and fuming out the house. The limited idle times, is to protect the environment primarily but also the trucks emission systems and diesels in general don't like idling for long periods of time. A waste of fuel and hard on the engine. Diesels will wet stack, or wash the cylinder walls from long periods of idling with excess unburnt the diesel fuel. The way to avoid that is the hi idle mod from an upfitter switch.

This increase in idle will charge batteries, run everything better electrically and avoid the wet stacking. This is why I got Forscan for Christmas and an OBDLink is so I can remove the double honk, set up high idle and be able to to this for the sake of my family and dog. Summer for AC, but more especially for winter cold.

We just had a 3 week spell of -20 to -25 C, and we are about to go back to it for a few weeks again. We had a few days of -35 for nights, all this idle time and warm up time and cold temps is killing fuel mileage for sure.

 

I am working where temps have been less than 15d F all day. Working nights and having to idle the truck for long periods, it will idle long as needed with the auto off unchecked, or it will tell me every 15 mins it is going to shut off in 30 seconds without hitting the 'off' button--with the key in it. If I happen to be in the truck long enough, it will regen at least once a night during long idle periods, sometimes twice.
Don't like to do it, but the idling is necessary for work.

 

J Standard, it's the clean air idle mandate by the Fed. I have Pete 389's and the 2018 has a 5 minute shutoff if the parking brake is set. There's no work around in the factory settings. The only way to keep it on is to release the brakes within the 5 minute window and it resets the timer. The smaller trucks will have a longer time programmed but will still time and but at the least they're able to give you a cancel switch, not on the big boys.
