I thought about doing that, but was just looking for an easier solution. I would rather not run it for 15 minutes when all it needs is 5.

I will have to look. But can't you set the run time on the screen

Shut down timer I only look for 1-3 minutes. An then sometimes more if I was running into the store for coffee etc.
The timer I had previously was adjustable from 1-60 minutes, 1-10 pushes of a button for minutes, 10 minutes intervals after 10 pushes.
User adjustable 5-10-15 minutes of remote start.

I know when I was ordering my 2011 F350 superduty there was option for the Engine Idle shutdown on the XLT models but not for the Lariat due to the Reverse Vehicle Aid Sensors. I ask if they could remove the Sensors and install the Engine Idle shutdown since I would rather protect my turbo then a bumper but was told that in the Lariat that was not an option.
With that said I had a Turbo Temp Monitor installed in my 2002 7.3 Diesel which would not allow the truck to shutoff until it reached 300 deg F. This would allow me to turn my truck off, lock the doors and would shutoff on its own.
I have provide a link below on what I had which it may still work on 6.7L with remote start but would suggest to call the Manufacture to confirm this.

I am pretty sure the engine idle shutdown most refer to here from the factory is not a benefit feature.
It is a Gov mandated diesel shutdown. It is designed to shut down the truck when you have idled too long, stinking up the air and wasting our precious fossil fuels.

The two factory idle timers I know of are (A) the CA required idle shutdown porthole mentioned and (B) the idle time out of the remote start when the key is in your pocket.
(A) is a selectable option depending on the state you ordered in.
Since I'm in AL, for example, I could idle my truck forever (if wet-stacking wasn't an issue).
I'm fairly certain SEIC overrides (A) and won't shut down (such as for PTO operations).
It would suck for a city crew to have their truck shut down while they're working on a transformer in a bucket!

Unless I'm pulling something heavy and have no time for cooldown when coming down to speed I never let it idle more than it has to. Idling burns fuel that could be better used to propel me down the road.
Running unloaded on rural highways really doesn't get the turbo hot enough for me to be concerned about cooling down. Even when towing heavy the time spent coming down to speed and putting into a parking spot gives the turbo plenty of time to cool.
At $3.99/gallon I don't waste fuel.

It's not just the cooling from the heat around the turbo. The turbo does not stop spinning immediately when you shut the engine off.
Depending on the load before shutting down will dictate the turbo RPM.
The problem stems from excessive turbo spinning without an oil flow. The oil around the bearing starts to heat up and if it is allowed to get hot enough the oil starts to break down, "coking". This inhibits oil flow which leads to bearing failure,.
This is more of an issue with turbos that do not have a water jacket.
But just the same, I'd like the option. It can't hurt and the extra fuel burnt is minimal.
I know it is not the same thing, but when our fire engines pull into the bay and are shut down you can hear the turbo whistle for 15-20 seconds.

Normal estimates show that most diesel engines burn about 1 gallon/hour while idling. Say you have your turbo timer set for 3 minute cooldown, and you use your truck an average of four times a day x seven days a week. That equals 1.4 gallons each week, and at my current fuel price that means $5.60 each week in fuel to the turbo timer.
Multiply this by 52 weeks in a year, and you spend $291.20 each year and 72.8 gallons of fuel. Fuel that could have been used to propel the truck an additional 1,092 miles assuming an average of 15 MPGs.
And assuming that same 15 MPGs you'd be burning 800 gallons of fuel during a regular 12,000 mile year. 72.8 gallons is a full 9.1% of your annual fuel bill.
I don't want to get 9% less fuel economy for something that I don't think will make a meaningful difference in the life of my truck. Yeah, the truck costs many times that amount, but the reason I can afford this truck is because I don't like to waste money.

I understand your point and I would guess that you don't use the remote start either.
I don't necessarily need to use it all the time, but I would like the option.
As I mentioned before, the last 100 feet of my commute is up a steep driveway. That means the turbo is working and I'll let it cool down a minute before shutting down.

When the truck is running, key on, you should be able to press remote start command, remove key, exit, lock and walk away. The remote start will shut off after the prescribed time. An egt below 400 f is fine for shut down, i would say even 500 for water cooled turbo. The cool down is only required after working hard, if you have been towing or high gcw i can see some idle time. Without an egt you are guessing. I have pulled serious hills, puled in for fuel and by the time i have got stopped at pump i am down to 400. I would bet with an egt y ou would find even more so the vase for necessary coll down with a water cooled turbo is far more rare now.

That would be nice, but is not the case. I've tried it to see if it would work and it does not.

I am installing next weekend the Compustar auto start system that has a turbo timer. Unfortunatly it does not regulate the tempurature all it does is start a pre programmed countdown when the key is removed. After the truck shuts down the remote tells you the truck is turned off.

I plan of buying the same unit.
IF I ever get my truck
I know with my older compustar, I could shut off the engine, lock the doors then re-start the engine and walk away. Once I'm inside the house, I can iether wait 10 minutes for it to shut off or shut it off at any time I like just by hitting the autostart button again. Easy.
