Howto: 05-06 High Idle (AIC/SEIC/BCP)

One of the posters on an earlier thread said one hour = 33 miles.

I may be asking a question already answered -- I have an Automatic Idle Controller mounted in my 2000 Excursion. Is that option not available any longer?

I am looking to buy a new truck -- any difference in the '06 or '07?

Hello all, I just traded my 01 7.3 for an 06 6.0.

I'm getting ready to do the idle up mod and have a few questions, some could be construed as stupid questions, but I'll run that risk.

1. Are there any warranty issues with performing this modification, of course taking into consideration you don't connect the wrong wires and blow something up.

2. Which one? SEIC or BCP? All I want to do is to idle up to prevent wet stacking, keep cool in the summer and warm in the winter.

3. What does it mean on the BCP to "lock the torque converter". I noticed the BCP does not do this. Are there any adverse affects to the torque converter being locked?

4. If I perform this mod, is it going to affect the automatic idling up during cold weather that I hope this truck does as all my others have (7.3's that is).

Thanks in advance for anyone responding to these questions.

Just did this on the '07. Works perfect. I used a short piece of wire. Makes the connection much easier and gives you room to work the next time you have the fuse panel down for other mods.

I was wondering if 6SpdStrkr's questions were answered? Could you share with the class? ;^) I would like to do this mod also and would like to know "Which one? SEIC or BCP? All I want to do is to idle up to prevent wet stacking, keep cool in the summer and warm in the winter." before I start. Big Thanks JAck

Here is my take.... please correct me if I am wrong:

1. Warrantee Issues: I don't see how since this feature is already included in the programing of the vehicle.
2. SEIC only idles up to 1200rpm, the BCP (Battery Charge Protect) will idle up to 1200rpm initially and is supposed to idle up a little higher if the battery is not maintaining its charge at 1200rpms, in order to maintain it.
3. If you do not have the PTO option to run accessories off...I do not see the benefit of hooking up to the SEIC. At least with the BCP you get the high idle AND the additional feature of ensuring your battery maintains charge as required.
4. No it will not affect the cold weather strategy....unless you turn on your high idle. Your high idle will overide the cold weather stragegy if you turn it on. (at least thats how it was on my 04)

Did it yesterday in my '06 on Aux 1. Took a little longer than expected due to my Clifford alarm install which was crammed behind the fuse box, I would definitely use a 6 inch piece of wire to make things easier. I chose BCP.

Click on The Truck in my sig, I have some pics of what I did. I used a small switch (push on push off) from Radio Shack and a 12v LED as a indicator and wired all that together.

[MX727]

BCP. Don't waste a 30AMP Aux switch on this mod. Use #3 or #4.

Checked in with the upfitter who is installing a Knapaheide body and Liftmoore 6000# all hydraulic crane on my new F550 4X4 service truck. They will have the SEIC wired into the crane control for the 1200 rpm boost. I think I will do the BCP setup myself when I FINALLY get the truck. There is a lot of info available at the www.fleet.ford.com/truckbbas site. Download SVE bulletin Q-108. This works only on F and E series trucks over 8500GVW and with "Transmission Power Take Off Provision" option code 62R.

I am currently running a 95' GM HD3500 6.5 TD service truck and it has a SEIC feature that is a 12V signal to a terminal in the PCM. This also came with a switch on the crane control and I put in an additional switch on the IP to use when jump starting or other times as needed.

Ok, this may sound like a stupid question, but here goes.....
So if after simply connecting the #4 upfitter switch to the BCP wire, and theafter the #4 switch is turned on, the system essentially monitors battery state and will automatically and variably adjust the idle to keep the battery voltage level up during peripheral equipment draw, why would any one need to purchase products like the "throttlecommander" or InPower's "Electronic Throttle Module"??

[RJ550]

It's not that you need to purchase it so much as the aftermarket people NEED to sell more gadgets. The Aftermarket throttle commanders and such were necessary on the 7.3's and now with full electronic throttle it's a DIY project. I believe any vehicle or heavy truck or equipment with an electronic throtle can do this. The accelerator pedal on electronicly controlled engines is nothing more than a potentiometer telling the PCM to increase RPM when depressed. By knowing the voltages and right pin on the PCM you can make the engine do most anything you want.

To answer everyones question about not having upfitter switches and doing this mod. What you would have to do is install a toggle switch somewhere on the dash. Then apply battery positive which can be found at a blunt cut wire behind the diagnostic connector. This wire is hot in the run position and the color is white/Lt. blue. This will tie to one side of your switch. To the other side of the switch you would apply to the PTO otput to raise the engine speed to 1200 rpm stable. Or tie it to the Battery charge wire to have the engine speed vary between 1200 and 2400 dependent on battery voltage. The wire colors are: orange for the PTO enable and Purple/Lt.green for the Batt. Charge enable. To change the idle speed while using the PTO mode you would connect a 10 turn 1/4 watt 45K ohm pot to: PTO V ref which is a orange/red wire and the other side of the pot to PTO rpm which is orange/yellow wire. Jump the third connector to one of the other terminals on the pot so that the resistance falls as the pot is turned clockwise. I have not tried this to see if it is true but this is how the chart list the resistance on the link below. When the pot is at 43k you will be at 1200 rpm and as you decrease the resistance the speed will raise to 2400 rpm. If there is anything that does not seem right about this please post. I am going to try it tonight. Please refer to the link below for further clarification. Thanks for the good stuff guys.

To throw some things out there about wet stacking. I have a 2004 f-350 service truck for work. When i am on a job site in the winter it will not be uncommon for me to let my truck idle at base speed for 4 or 5 hours. The extent of the wet stacking would be a sizable cloud of white smoke when you leave the site and put the truck under load. It will smoke for about a 1/2 mile or so. The white smoke is the unburnt fuel in the exhaust system. We have a truck that had a PTO on it and idles to 1200 rpm for the compressor and the crane. This truck idling high for a few hours will still blow some white smoke when you leave. I think that really there isn't much of a difference with the idle elevated. It deff. keeps the truck warmer. I have inspected the exhaust manifold for any signs of fuel or goop dripping at the end of the day and it seems fine. I have seen people set up exhaust brakes to close at idle to force the engine to build higher exhaust gas temps to prevent wet stacking. We have a few cat C-9's in the bigger trucks that they do this to and it seems to work alot better. I think the brake is only closed part of the way. Well end of the story i have 165,000 miles on my truck and it has idled for extended times. The engine still runs great and has not needed any major service. I hope that may clear up any issues. please post to add or coment on this. Thanks guys

Thank you for this. Took about 30 minutes to do.
