"High Idle" basic info?

[Wolfy]

Trying to get a concise thread about this "feature" , to help newbies(such as myself) get a grip



1. What is "high idle"?



2. Why do I/you want/not-want it?



3. Why is it not "standard',... but must be dealer/mechanic activated?



4. Anything else important to know/consider about HI?



Thanks!

Not 100% sure. But based on my limited time with a 6. 7 on a test drive, and cold weather (17 degree morning), I do not think that high idle is an option any more on a 6. 7 with a 68RE (non PTO capable transmission). As for the 6 speed manual, not sure.



My logical reasoning (could be 100% off). The exhaust break is part of the turbo and standard on all 6. 7's. While the truck was idling after our test drive you could hear the exhaust break kick in. Just like the 5. 9's do when they idle to long, they go into high-idle at 1000rpm to keep warm.



I did attempt to set the cruise and get the high idle to run manually. This was a no go.



Since there is no PTO on the 68RE, there is no need for manual high idle.



Tho, on a G56 manual trans it may be logical to assume you can enable a high idle feature.



Does this sound right?

Intrested as well

Wolfy,



I'm real intrested in this topic also, and specifically issues in answering question 4?



4. Anything else important to know/consider about HI?



If indeed our new DPF's only regenerate at highway speeds (computer controlled) what impact will enabling a high idle feature mean to the DPF?

How long @ HI before it can clog the DPF? etc.

Guys,



I am a newbie here myself and all, but I can tell you that I have a new 6. 7L and with the auto 68RFE transmission and I had the service guys at the dealership turn mine own and we did this in the parking lot and in less than two minutes...



No wires to ground or anything more than the ECM switched on for this option. Works flawlessly also as I use mine every night of the week. I idle mine up to run the lights in my gooseneck trailer while I load up as it may take from 30 minutes to an hour to load up and at a dead slow idle would certainly really be bad on the motor...



I have had the high idle on a six position flip switch on my last diesel, which worked but it was set for only 1100rpm. This one once set will start with the turning the cruise on and push and hold for a second the set button. That will have it at about 1000 R's and then you can use the accelerate button of the cruise to speed that up more from that point. Works really slick guys I promise you...

Hey I want this option on my truck. Anyone else had this programmed? Maybe I can get Adam and Dishman Dodge to program mine when it comes in.

From what I understand hi-idle is a warm up feature for the engine. My truck came with it. After start while the engine is still below normal, if I let it sit for a little while it idles up to about 1K. As soon as I start to put it in gear it comes down to normal.

There are two different high idles. An automatic one that comes on when the ambient and engine temps are low, and a manual one that uses the cruise control buttons

Jeb-H and Bob V's posts make sense

I've asked Adam to beat the drum with his techies on this issue... Both Jeb-H and Bob V's posts make sense... Obviously this is a feature I'll wan't enabled also when I pick up my new 3500 this week, just want to make doubly sure that it won't harm DPF function/longevity and that the reason there's so little product knowledge out there on this feature is due to the newness of the 6. 7L.

I stand corrected. Doesn't make sense to have an high idle and no PTO. Have you noticed the exhaust brake come one as well when you place the truck in high idle?

 

[Bob V]

Yes, the exhaust braks will stay on unless you bump up the RPM over 1100 (or engine temp get over the setpoint)

ahh interesting, taking the best of both worlds there.

Happy Days

Just got off the phone with Adam he states on page 286 of the owners manual you can find a description of the operation of the driver actuated Hi Idle feature, and also that it must be enabled by your dealers serice personal. So I gave him a big upcheck to accomplish on my truck... I'm at T minus 36:00 hrs and slowly counting down!

PL,



The DPF would be way better off if you idle for longer periods at all at a higher idle speed as this will help keep the heat or at least a higher heat in the exhaust system dude.



That will in turn help keep the solids the DPF traps burned down somewhat, at least more so than a normal idle speed... I don't understand why this doesn't come already on and ready to use on all of these Gotes'.

Jeb,

I'm way cool now, learning that it is in the owners manual and that it instructs you to request dealer enabling if desired has alayed all my fears!!!

Adam has promised to scan page 286 of the Owners Manual and send it along I'll post here soon as he does so.

Excellent Oo... . thanks Pete. I will have Adam get the tech's to turn the feature on for me as well when my truck gets there.
