Dealer said no high idle.
 

So I took my truck to the dealership today to have the high idle turned on and to get my speedo recalibrated. I left with a sore ass and badd news.:moon: Shop guy says my truck doesnt have the high idle option. He said it had the 3 cylinder idle but he didnt turn it on. My speedo now shows 3 mph faster instead of 5 slower.:td: Sorry needed to vent. Is it true that my truck has no high idle.

Thanks

The High idle is part of the software that Cummins put into the ecm, dodge did not use it. If someone near you has a SMARTY, all you have to do is upload any program onto your truck them return it to stock, and you will have the 3 cylinder and the high idle modes.

What he said, although the Smarty wont recal your speedo if you remove it.

Can my local dealer enable the high idle. Or if he enables the 3 cylener idle will this also turn on the high idle. I dont know anyone with a smarty.

Your dealer is a crackpot when it comes to diesels. But then again, most of em are. The high idle and three cylinder shuffle are all a part of the same update. Under a certain temp reading it locks out 3 cylinders and over that temp it only activates the high idle. Some place here on the site is a thread that tells exact temp ranges for each function and the flash number and info for the update.

I think, the dealer should be able to turn on the 3 cylinder/high idle. It only works when certain parameters are met. The high idle will rev the engine to 1200 rpm at a certain temp., while the 3 cylinder idle will turn on when it is colder.

I have to go back to get him to fix the speedo and when I do I will have him enable the 3 cylender idle and see if that works.

could you just go to a cummins dealer? i dont know if they do trucks. just an idea. or buy a smarty. or buy a ford :w2: nobody hit me lol

No cummins dealers nearby, and I dont really have a spare 600.00 for a smarty. No thanks on the ford offer, unless its got a cummins in it. :moon:

x3 you can do it with the smarty I had one in mine but i took it off and sold it. but i still have the high idle feature. Which is so nice
