03 powerstroke 6.0 whistle

anyone here know how to make a new duramax get that sick 747 JET whistle from the turbo?????

 

Trade it in on a Ford????

You might get more hits in the Chevy forum....

 

That PDF is pretty involved. Can someone translate it into more simple instructions? For the Stupids like me? For an '08 F350 PSD Thanks.

 

Is the seic wiring directions for the 08, the same for 09 trucks?

 

I made the connection to activate the SEIC using one of the Auxiliary Switches. It is a very simple connection (two wires), if the default RPMs (1200) will be used. Thanks SmokeyWren for the useful information.

 

Ford has included logic for elevated idle control in the powertrain control module (PCM) since the 2005 model year. It's called the stationary elevated engine idle speed control system (SEIC). But you have to hook it up to make it work.

The SEIC is not just for power take off control. It's also used to elevate the idle RPM for battery charge protection, or for extended idling in hot or cold weather so the heater/ventilation/air conditioner (HVAC) systems will do a better job.

Here is a link to Ford's procedures for how to install the bits and pieces to make the SEIC work in a 2008 SuperDuty truck:

I did the high idle mod but i want to add a potentiometer, after looking at that diagram it show the green pto_rpm wire being grounded which I understand but what I dont understand is it says pwr grd 4.75k, what does the 4.75k mean, do i need to add something to the ground or something

 

That would likely be a 4.75K OHM resistor? (To get the right RPM idle?) These trucks are TBW so the odds are they just tap into the throttle at the PCM? That would be the resistance through the pedal at 1200 rpm I guess.

 

Usefull information to connect an Upfitter Switch to activate the SEIC

:read:Attached are the two documents that I used to do the connection to activate the SEIC using an Upfitter Switch.:thumbsup:

 

Do I have this right (for 2008 PSD)? Hook the yellow and green (from my SEIC cable bundle) wire up to one of my uplifter switch and I am good to go?

 

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.

 

Just did mine, 3" of 16 gauge wire 2 butt connectors and I have fast idle.

 

so you use this only when your parked? not while your driving?

 

The name is stationary elevated engine idle speed control system (SEIC). When driving, you're engine is not idling.

 

Where exactly do you find the SEIC wire?

 

high pressure pump failure

Sorry,,don't mean to change topic but new to this,,,have 2008 F350, 6.4L Diesel,,89K miles,,bought extended warranty ,,recently went down,,told by service tech that there was water in fuel,,so Ford warranty will not be honored...tried to turn in to insurance,,adjuster sent 2 samples from fuel system,,reported that insurance will not cover because lab report (which I have) found "no water in fuel",,,,,leaves me holding the bag,any ideas ?

Yea change the fuel filters and try to get your hands on some of that Diesel 911 stuff. Then after a month change your filters again and pray you got it all.

 

Alright guys, i found the wires and all, I'm puttin new shoes on the old girl here in a couple hours, when i do i'll wire her up. I'll let ya know what happens haha

 

Subscribed to thread.

 

Finally did it. Easy 5 minutes. Thanks, guys!

 

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

 

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.

Nah, not daid yet. Now 75 years old and decrepid and taking 13 pills per day for diabetes, heart disease and eye drops for glaucoma, but still feel good. 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.

I am really needing some help ? 2008 f350 6.4 , The POT hook up didnt work , so I cut them 3 wires , and just went with the aux.4 brn wire to the yellow and grn STRIP wire ,still no idle up.."AWWWWW" !
