That Dfuser unit seems like a decent package. It's probably just a work around for the IVS and TPS sensors but it probably does a good job. One benefit is that you can locate the rotary **** someplace convenient. My one complaint about the Ford AIC modules are that they are quite huge and take up a lot of real estate inside the cab...

 

I agree. It is the best AIC model out there but has way more features then you really need.

In your profession I bet you know a lot of EMT type folks who drive ambulances. See if you can find out who services those vehicles and ask if they have any of the ambulance models available. They would be the units without the displays but they still would work fine. Any salvage yard that specializes in ambulance or emergency vehicles would probably have lots of these items on hand and it's likely they won't really know what they are for.

Just an idea...

 

I really want the AIC for it customability, I am thinking if a go with this I will hold off on a chip for a while. The one from defuser is okay but I like the plug and play that the ford unit offers. Just trying to be economical, wife's been in the hospital twice this month so a little tight on the funds.

 

Hey John,
The guy just posted it on www.plowsite.com. $175 and the video.

 

(bringing back an old thread...)

I'm going to give it a try...
I have a friend at Ford who's willing to hook up and see if he can access an "enable PTO" function.

 

I hope you have some good luck.

If you still have stock programming on your PCM, then you might ask your friend to reflash the PCM to match a truck that would have had a PTO transmission. I think the dealer can look up the calibration code by options and choose the one that fits. After the reflash, you will probably have to drive the truck for a mile or two and then immediately pull over and apply power to that wire. Ford says there is a 'window of opportunity' to activate the high idle feature but they never give any more specific details that I've ever found. It would be a good idea to temporarily wire up a switch so you can have it ready after your friend does his part.

Good luck.

 

OK, I'll get something wired up and ready.
Just to be clear, there are two 'light blue/yellow' wires. Which one worked?

The one that runs to the OBD connector, or the one that runs to the AIC connector?

 

Use the one that runs to the OBDII connector. As near as I can tell, the other wire (in the AIC) harness is a disable circuit. A couple of our trucks have that circuit grounded when the landing gear is retracted. This means our guys can't operate the boom unless the landing gear is lowered (since the engine won't fast idle...). I am not sure if that is the correct use of that other wire but that is the way it is on our trucks.

In the attached photo...the blue w/yellow wire that has a crimp connector is the one that you want. It just so happens that this particular truck was outfitted with an ETI aerial boom and Muncie PTO pump and it came with a dash pod control panel. That panel had a wire harness that was color coded to connect up with the factory wires under the dash and has it's own power feed that connects to the enable circuit. So that is why we didn't need to use the blue w/pink wire for 12v power. (hope that makes sense...)

My wife's truck is a regular pickup without any aftermarket stuff attached but it did come with a PTO trans. On her truck, I mounted a simple toggle switch on the dash and routed the two wires down to the area seen in the photo. I then connected one wire to the Blue w/yellow in the OBDII bundle and the other to the Blue w/pink that was next to the Customer Access circuits. That worked great for her truck and seems to be pretty handy.

 

man i would like to try this

 

Got it.

This is my plan;
Wire up a switch that will apply 'key-on 12v' to the PTO enable wire.
Return my truck to stock (I have some IDP tunes I run via SCT XCal).
Have my buddy look to see if there's a 'user adjustable parameter' in the existing PCM calibration - if not, have him re-flash with code for a truck with PTO. Now, hopefully I won't need to do this, but If I do, I wonder how easily it can be done? Replacing stock (non-PTO) code with foreign code?

With my wife due any day with our first (baby boy), I have to tread lightly on "garage time". So this may take more time than I'd like. But I'm committed - gotta try it and report back to the brotherhood. Stay tuned.

 

Shouldn't be a problem as long as the PCM family is the same. I'll try and get my wife's PCM code tonight so you can have that as a reference. Her truck is a 2000 F250 Lariat.

I know that one of our work trucks had the PCM replaced by the dealer and when we got it back the PTO didn't work. We took it back and they said the new PCM had the wrong calibration. After some phone calls with the main office at Ford, they were able to reflash the PCM and then the PTO worked after that.

At least that's the story we got from them.....

 

I wonder if replacing the PCM code will have an affect on my Innovative Tunes? If so, im sure Eric can reload 'em to work for the new / different code.

 

That would be great. It'll give us (my friend and I) some point of reference if we need it.
Thanks!!

 

I hope you get this to work. I could figure it out and finally with help from FTE got a good deal on a ford AIC controller and couldnt be happier. Good luck though.

 

I wonder how many different PCM codes there are?
