Hi Guys

I'm the new powerstroke guy thats coverting to the Dodge side ...I am most likelly going with a new 06 truck ...once I figure out what I wan't .
I did consider a used 2002 only for the reason of dana rears ...I have allways had them .
My question is about the cummins ...I wan't one , I know that ...LOL ...I know with the 7.3 powerstrokes there is an issue with leaving the truck idle in cold weather , a condition of wet stacking ... unburned fuel deposits building up .
I have in the ford a controler called an aic ..it's basiclly a computer control for a pto to bring up the rpms .
Is this a condition that can is present with the cummins , and if so what are you guys running .
Thanks guys

Greg

 

I have read that this can also be a problem with the cummins, especially in colder weather and for extended idle times. I have a Practical Solutions High Idler on my 2000.

Hello Greg,

Any diesel shouldnt be idled for a long period of time due to temperature not being sufficient to burn the fuel efficiently. This results in carbon buildup, oil leaking turbos etc. 5 min. is usually the max to idle at idle speed. However, a device that bumps it up with a flip of a switch to around 1100 will cure your idling concerns

 

Does anyone make a "high idle" kit? Will they work on a standard shift?

 

Home Depot. They call it a brick.

There is a high idle feture for cold weather. ISB (real Cummins) have high options.

2002 should have the "high idle" function ready to go,
Mother Dodge in her infinite wisdom though, opted to ship the trucks with this feature disabled, you will need to have a Dealership enable the high idle, for which they usually charge $40-$50 bucks.

There is a TSB regarding this, it is helpful to print it out to present to the service guy when requesting the "flash".

Ive got an aftermarket high idle switch and an exhaust brake. Both work great for keeping the combustion temps up.

 

The high idle feature on the 2nd gens only works on start up. After its warm it doesnt work anymore. At least it doesn't on mine. I use a stick between the seat and the throttle, and bring the RPM's up to about 1500. For has a deal where if the pickup sits for about 10 min it automaticly idle's up to something like 1300.

 

If you have a exhaust brake that is enough to keep the pyro at about 400*F (idle 800 RPMs) compared to high idle 1200-1500 RPM's at about 300-350*F
I'm pretty sure 400*F is hot enough to burn the fuel completely... IMHO

All pyro temp here are PRE TURBO...

 

my idle temp is 330ish on my truck... and i leave it idling for long periods of time all the time think it hurting it at all?.....some nights ill leave the truck on and take a knap across the bench seat.....

 

I have a 03 and if temp is below 35f my truck will kick up in high idle on cold start and after its warmed up. I think it takes about 2-3 min @ idle then it kicks up.

 

Hi guys

I have never left a diesel idle more than 5mins ... unless I was letting the exhaust temps cool down , I see so many people that leave diesel engines idle and I ask them how long there going to keep there truck ... most guy are under the asumpthion that the can idle all day ...Not 1100 rpms keeps them temps up ... like I said this controler I have has presets and I have to do is set the e-brake and push a button and I'm at 1200 rpms .
Dose anyone know if the 06's have a built in high idle that sence's low rpms .

Thanks guys .

Don't idle the truck unnecessarily-- period. However, if you HAVE TO (I can't conceive where it would be a necessity), just get it good and hot again before you shut down. If you tow heavy, this isn't a concern.

Idling and loafing are much worse on these engines than pulling 20K up a hill, imo.

 

It should be noted that periodic idling of 5 minutes +/- will not hurt the CTD.....it takes successive periods of several hours in cold conditions to cause any problems.....like idling at a truck stop all night.

 

Geno's "Throttle Pedal Depressor" works slick. Played with one for a week. Spring loaded **** for adjusting RPM, can be used anytime...not just start up and is cheaper than Reflash!
