High idle on a Cascadia Smartshift

Hmm, you know too turn on the cruise and hit resume, then toggle up or down to adjust the revs.
Unless it's been locked out.

 

ECM probably set so you can't do that. Probably need to hook up the computer to it and check the settings.

 

Have you tried setting the idle up with the trailer brake locked and tractor brake released? Cant really think of anything else.

 

Company truck with opti idle or anti idle it would be off. They use the ambient air sensor to determine wether it can idle or not. Most companies are setting about 40 degrees to 68 degrees as a window the truck won't extended idle. If it can idle at the lower setting for long periods, it won't hurt anything more than it would at 1000 rpm.

 

Yeah the work around for that one is drive nights during the summer, and days during the winter. I drove for an outfit that had it set at 40f and 80f.

 

Thats a good idea! Don't know about carbon build up but we always bumped the idle up on the pre-emisions engines because it was smoother and supposed to be better for the engine and turbo got ample oil supply.
