Hgh Idle
I bought a new 2019 F450 KR two days ago and am still learning about it.
Is there a way to have a high idle on this truck? On my Ram 3500 that I traded in, you just put it in park, turned on the cruise control and then hit the "set" button and you had an uptick in the idle speed.
Can I do that on the 450?

You have to wire it up. You can wire it up with a resistor and some wiring to an up fitter and have a set high idle point or get a kit from bd deisel which is plug and play and has an adjustable dial.

There is an automatic high idle but it only revs up to about 1100rpm just like the rams automatic high idle. I hated the Ram in winter because I would have to run outside to do the cruise control high idle option for a chance to have it warm up in -25C weather. The ford warms up great at those temps and temps down to -35C. Of course the operating temperature will be low if left at idle for a longer period of time.
Are you thinking of adding a high idle switch for cold temps? If no, why do you want a higher idle?

If that was your plan, you really don’t need one. These trucks are built to be anti idlers. Idling and especially high idling isn’t good for the emissions systems. Even ford recommends only a few minutes of idle time even in sub zero conditions. I could see a high idle in the winter if you let it idle a lot because the truck would struggle to keep steady at a normal operating temp. Idling these trucks below operating temps causes combustion issues. A high idle is needed in that situation.

The SEIC wires are behind the passenger kick panel. I cant remember if the info is in the manual but videos can be found on youtube that detail where the wires are, what resistor to use and how to wire it to an up-fitter.
Heres one haha....
There are others that may be a little clearer and that use a resistor rather than a potentiometer.

I read in several threads in the past that the emission system can be short lived if you don't use High Idle for extending idling.

Cold start idle strategy will do this automatically for cold starts. No need for hi idle mod. If you want increased cooling, battery charging with hi idle, the Upfitter mod is useful. But yes, it does have some consequence to fuel consumption, and to DPF longevity. Significant idling requires stationary regeneration of the DPF.
Really hi idling is for the older engines without the EGR, DPF, DEF systems. It was used to prevent wet stacking, which Is in burnt diesel fuel on the cyclinder walls washing down and increasing ring wear amongst other things. Something to think about is that with these new engines, endless idling is a no no. However, when you do find situations where idling is necessary, then the hi idle is the way to go, and fuel consumption is a definite consequence.

There’s a pretty noticeable difference in AC performance between idle speed and a higher idle. During extended idling my AC can stay on high the whole time and it works OK but it’s not super cold. Switching on high idle gets the air nice and cold and I actually have to turn it down.

I know the high idle for AC in the Rams really effects the operation of the AC while idling. It would not blow cold in 30C weather until the high idle kicked in. This ford seems to be great without the high idle. That being said, It doesn’t get hotter than 33ish degrees Celsius where I am from in Canada.
