mine also does that when it is cold and not plugged in i dont have a smarty i have a bully dog

 

My truck does the same thing once in a while with the smarty or stock.
Try starting the truck with the parking brake off or with your foot on the brake pedal. Then after it starts put the parking brake back on and take your foot off the brake pedal. The truck will idle for a minute or so then will go into high idle on it's own.

 

Stock it goes right to 1000. I doubt it is that hard on it and I am sure it does less damage then rolling down the street at 1000 after just starting. Mine will ramp up to 1000 idle even with the engine warm (185 to 190) if I put it in park and it is in the teens outside.

 

I always have my foot on the brake when I start the truck.... I have a handshaker and it is just habit to start it with my foot on the brake...








I am defiantly crazy!!! thanks for reassuring that guys



Guess I better remember to plug it in if it bugs me that bad....
thanks for all the comments

 

mines does it to stock or not. ecspecialy right night -27C in the morning even with it plugged in.

 

Cold winter front will help.... Mine used to do it all the time now it will start for a while before it hits the high idle...

 

mine does it, and i dont have the programmable high idle flash either

 

Got this info from another site....when the ECM see's colder than 32*F rpm's auto ramp after 2min of straight ideling. When it see's colder than 15*F instant auto ramp to 1100. You can deactiviate it by depressing the brake pedal, but it will reset and after 2min will auto ramp again. It's to keep the alternator running in it's effective zone so when the grid heaters cycle and the fuel heaters are on and all your other power drains are on it wont strain the batteries. Mine did this even before my SMARTY. I think it is DC autoprogramming.....

 

Smarty will also activate 3 cylinder idle on 3rd gens when really cold. Used to be only a 2nd gen feature. Really should think about 5w40 syn. oil and deep freeze temps!

 

mine doesnt?

 

I am pretty sure the 3rd gens dont have the 3cyl idle....Smarty does enable the PTO switch tho..witch means you can bump the idle up with the cruise buttons.

 

ya it bugs the heck out of me too. I keep hearing my dad in the background yelling at me to "let it build oil pressure before you run it up against the limiter"!! seems as though the brains at cummins or even dodge would at least put a delay in there so it could build pressure before a 1000 rpm dry start.

 

Well, i had mine plugged in last night and it did not do it. I know for a fact yesterday morning was the first time. High idle has always kicked in after 2mins in cold weather. I have been in Illinois hunting on several occassions at 10-20 dregree weather not plugged in and like before high idle after 2 mins.

Who knows, maybe it was part of hte new software released by DC.

 

The '05 never burped out a high idle rpm on start-up until the Smarty was loaded, and then only if it was on an aggressive timing SW.

As far as the oil pressure, sometimes I can count ten alligators before the AutoMeter needle moves...

 

I know engine builders that would disagree with your dad. Getting some rpms right away gets the oil moving around a heck of a lot quicker.
