My kid just bought a 2011 3500 4X4 Crew cab standard trans and the dealer told him because it's a standard there is only an 1100rpm high idle for cold WX warm up. After he left town for up North they contacted him and told him they can now increase the idle to 1400rpm. Anyone have any thoughts on the high idle?

 

i like it and use it all the time. slept in my new truck on the way back from the dealer in Idaho. idled @ 1200 rpm for 2 hours

 

Is yours a standard transmission? I understand the auto's are no problem but the std is.

 

mine is auto but it is doable on the std tranny

 

According to H&S the 2010+ trucks do not have the software option for manual transmission trucks.

The only way to currently do it is with a minimax or blackmax.

 

Thanks, I guess they didn't plan on selling them anywhere cold. They must have just come up with something though as they contacted him and told him they can now do 1400RPM on the standard trans. I'll investigate further when he gets back in town maybe it is just an updated flash to the ECU/PCM.

 

If the 11 is the same as the 08 there is a green wire(with heat shrink on the end of it) stubbed out through the firewall, It needs to be grounded then the dealer can enable it. They will try to sell you a clutch cut out switch as well..it is not needed as the truck will return to normal idle when it detects F or R motion. Automatics have this wire grounded already:

 

Just for my education, what is the high idle used for ?

In the olden days we had a manual twist **** to turn up the idle for when we were using the PTO to power something such as a winch or pump.

 

Not an option on the 2010+ manual trucks.

It's design was for PTO service, which is weird that they discontinued it, but the G56 still has a PTO port.

It's also nice for faster warm up, cool-down, or to increase the load when idling for extended periods.

 

I don't know about the 2011 but my 2001 from new even when warm and left to idle for long in really cold temps will eventually start blowing clouds of blue smoke as the engine coolant temp gets colder and colder. The engine just doesn't generate enough heat at idle even with a winter front on it. I just use the snow brush trick but that doesn't work if you are sat in traffic.

 

Thanks for the update AH,

I would really love to take a Dodge engineer for a drive when it is -40 or in the mud associated with our spring thaw..

No one builds what I call a work truck any more!

 

What is the snow brush trick?

 

Ummm. Wedge a snow brush between the accelerator pedal and the seat.

 

50k+ For a truck that you have to resort to a cave-man-club to make hi-idle... I'm really impressed Dodge!

 

My kid's last truck was a Ford so he actually looked at Ford and GM but he said they don't make a standard transmission with a diesel anymore? I can't see it but that's what he said, maybe he just wanted a Cummins.
