I just ordered that kit. Too slick to not have, even if I don't use it much. 
I like having a truck like this, with many ways to customize it! Tailgate assist goes in tonight, and Pop and Lock tailgate power lock soon.

Cool kit.
I couldn't justify the expense nor the need for an adjustable idle control. A $3 resistor and 3 butt connectors is all it cost me. I read here that a Ford Tech recommended a minimum of 1200rpm for high idle but don't remember why.
I just wish it worked with remote start so I didn't have to go outside and freeze first thing in the morning. The upfitter switches are inactive until the key is turned on.

To get an idea on the increased rpm's that the engine will do all by itself take a look at the rapid heat link in my signature. At 5 degrees F ambient temp it was idling at 1200 rpm. At 12 degrees F ambient temp it was idling at 950 rpm. In my experience with extended idling the truck will automatically raise the rpm to keep the engine oil temp around 150 degrees F. I noticed this after leaving the truck running while I was in a store. Came back and it was idling faster and the oil temp reading was around 150. It was around 190 degrees and idling at normal rpm when I went into the store.

(my truck is deleted tho)
Good luck, I am sure the kit will work great.

Not sure what exactly it is based on but yes it for sure is. Mine works just like doc says.

I am continuing with the kit. I talked to the company BD Diesel, and he showed me right in the directions where it talks about how to wire for remote start, given that the ignition wire won't have power when on RS. It does mean I can't wire to the upfitter switch, but that's ok. I like the idea of using this at other times, than just when cold. For $65, no big deal. Install it and it's there if I want it.

Pretty cool data there!

If I remote start and it high idles up and gets the temp up, it will idle down, if the temp drops again, it will high idle back up. I've seen around 1500 rpm high idle, but that was when it was around -20F out. and it when up and down in rpm as the motor temp raised and fell. Motor cools off pretty quick in sub zero temps....
If you start it with a key, let it idle and walk away it will still high idle on it's own if the temp drops. (as long as the vehicle is in park). Here is where a high idle mod would help, with the key in, it does not seem to be as aggressive as a remote start in high idling.
It's why I say the high idle mod/kit isn't needed for your use.
High idle is use to prevent wet stacking... Higher rpms help to prevent that.

Got it. Thanks for the explanation. I have watched my truck on remote start in cold temps, after reading about this computer controlled temp senstiive high idle, and have never really seen my truck adjust...who know.
Like I said, the kit certainly doesn't hurt to have. Can always turn it off and then the truck is like it was before the kit. There are times, even with key in, that I would like to raise the idle after everything I've read. Especially when trailering my snowmobile trailer, and letting truck run with kids in truck (older kids, not young ones) in very cold temps, and for times of slightly extended idling with key in.

No the kit is fine to have, it isn't a huge investment, especially if you base it on the cost the truck.
Darren - Wet stacking has been an issue with diesel way before DPFs and SCRs were invented, however, I do believe that a non-deleted truck can be hurt more by extended idling than a deleted one.

Yeah, saturating the EGR cooler or DPF would be bad.

Does anyone know how the high idle will affect engine temps in a hot climate? I would like to add the kit just for high electrical usage at idle, but don't want to overheat the engine. The summer temps average in the mid to upper 90's here.
