Does anyone know if this will cancel out the automatic shutdown after 5 mins. on the 08's with high GVW's? I'm sick and tired of having to restart my truck after 5 mins or so trying to defrost the windshield.

My question would be, do you HAVE to use the 1200 RPM setting, or can you add something to drop it down to say...800 - 900 RPM?

Need to add the upfitter switches (about the only option the truck didn't come with) first, and may very well do this mod.

Thanks Smokey!

Maximum engine speed is 2400 rpm.​

Minimum engine speed – Diesel engine: 1200 rpm

So using the Ford procedures, you can set the high idle RPM for anywhere between1,200 and 2,400 RPM. But not lower.​

With the factory option of the auxiliary idle control (AIC) on my '99.5, I had to use the factory mininum of 1,300 RPM as the lowest setting for high idle RPM. But after the AIC took over, I could mash buttons on the AIC that would manually lower the RPM to 1,100 or so. But you don't have those buttons on the SEIC.​

Here's my AIC, available on '95 thru '04 PSDs. For 2005 model year, the SEIC replaced the AIC.​

​

The buttons are hard to read in that photo, but they are for​

RPM control..........Charge Protect..........Power.........Ford
PTO Control​

The power button is simply the on/off switch. The Ford button is sorta like the enter ley on a PC - used for "programming" the AIC.​

And no, the AIC will not work on '05-up PSDs. ​

Quick question, after i wired mine up, it worked great. But now and then after i kick the parking brake on, and flip my switch, the engine tries to idle up, but then stops and i have a wrench flashing on and off on the dash. Any clue what the heck this means?

Any clue what the heck this means?

Ford calls that light is the malfunction indicator light (MIL), or some folks call it the check engine or "service engine soon" light. It means you or someone with the proper diagnostic tool needs to read the codes stored in the main computer (PCM) and see what your malfunction is.

Thank ya sir, it's odd, only comes on maybe 50% of the time, and only when i flip the switch for the seic. Seic doesn't work when it does this. If i turn the truck off and back on, the wrench goes away, and most of the time "fixes" the issue.

2008 f350 high idle mod problems

i did the high idle mod on my 2008 f350 6.4 and is only idiling up to 950 rpms instead of the 1200 that it says on the link any help? nvm on that when my truck warms up it dops the idil down to 950 but idils at 1200 when its colder or needing a battery charge but it still doesnt seem normal to me

Just to help some of those who don't like looking at wiring diagrams...Hook one of the switches (in my case #4 closest to the passenger side - brown wire) and the yellow/green wire together. You'll have to set your parking brake for it to elevate the idle speed. Without the parking brake engaged, it will disable the SEIC.

But wait ... hand up for a question

Doesn't the wiring directions state that you need to choose and add a resistor from the SEIC chart? In your directions, you simply route +12 from your switch/relay to the yellow/green PCM wire.

To my eye, it looks like you also should have had to place a resistor between white/brown and gray/violet to tell the PCM to tell it what RPM to idle at.

How would you use the SEIC for power take off? My roommate has an BMW M3 with Launch control and I want do power take off utilizing this once i connect it in my F250 and race his German-mobile butt...lol

First, your truck must have the optional PTO provision in your automagic tranny. If your automagic tranny doesn't have the PTO provision, then you must replace the tranny with one that includes the PTO provision. But the PTO provision is standard in manual trannies, So if you have a stick shifter, read on.

Next you have to install an aftermarket PTO in the tranny. The instructions for how to use the PTO will come with the PTO.

The most popular aftermarket PTOs are manufactured by Muncie and Chelsea. Do a Bing search on them to find their website, then go to their website to see exactly which PTO will fit your tranny.

We just returned form a "Dick Cutting" type of trip - made lots of miles without much time wasting to see the sights. 2,893 miles in 5 days, from 5:30 p.m last Wednesday to 10:30 a.m. Monday. Dragging a cargo trailer from Midland thru El Paso, Phoenix, Blythe and SoCal to Fort Irwin CA, then back to Austin to unload granddaughter's stuff, then home. I guess it wasn't really a Dick Cutting trip because our longest day was 700 miles from Blythe CA to Van Horn TX, and Dick does twice that many miles in one leg. Since my tow vehicle is an F-150 EcoBoost, no need to say much about it here except 9 MPG on premium gas is a slam to the ole pocketbook.
