So I spent most of last night reading the owner manual for the Ecodiesel. I wasn't able to find anything in there about an elevated/high idle setting for these engines. I was just wondering if there is such a feature? I know on all of my Duramaxes, there was a setting for elevated idle in the DIC, or a high idle setting with the parking brake set.
Thanks in advance for any responses!

There is no manual way of doing it. It is fully temperature related I think its 1100rpm @ 0C and 1400rpm @ -10C

GDE has a high idle option. It's based on ambient temps, no user control.

That's not GDE that's ram factory. It idles higher when the fluid is cold.

There is a high idle switch available after market. It's compatible for the ecodiesel but designed for the Cummins. Regardless it's just plug and play on the rams fly by wire. But it runs almost 200$ but has many high idle speeds. I'd be using mine for stand still forced regens whenever necessary. Will be put in over the summer for next winter.

GDE does have a high idle option in their new tune.

Gde tune ramps it up to 1500 rpm after it is started for about a minute to let the oil get thinner and it sounds more like a diesel

No such feature from the factory on the eco
That's not true, if you put the heater on FRONT WINDSHEILD DEFROST with the car temp set to high heat, when you start the truck, stock will run a higher idle in the cold (usually around 1300 rpm). It's not comparable to the GDE high idle, but it does exist.
