Interested in doing the high idle mod for cold mornings..Any info??

 

Never knew you could do that, I know on the TS and PHP switches, there are a high idle option but never knew there was a mod. So if there is one, I'd like to do it too.

 

yea, i read some where you can wire switches in and make your own high idle switch.

 

Well if anyone knows it's these guys. But it sounds a little to good to be true.

 

Here's some write ups on it..see what ya think!

Huh never heard of such thing, and I personally wouldn't go to all that trouble, I would just get me a chip with a high idle setting, but thats me. But yeah I want to listen in see what I learn.

 

Seems pretty cool to me and cheaper than a chip.

 

I like the writeup at North Texas Power Stroke Association - DIY AIC Mod

Note that you could use a single relay with double contacts like this one from digikey: Digi-Key - PB490-ND (Manufacturer - T92S11D22-12)
If you use the single relay it simplifies the wiring a bit.

If you are ordering from digikey here is a potentiometer: Digi-Key - SP534-2.0K-ND (Manufacturer - 534-11202)
plus the **** Digi-Key - 226-4101-ND (Manufacturer - OEDL-63-4-5)

If you have a hand shaker I'd use the E-brake switch as suggested in the article. If you have an auto, I'd suggest wiring into the line between the start switch and the transmission safety switch. When the truck is in gear, the switch will be open and the relay can't be engaged. When the truck is in neutral or park, the transmission switch is closed and the little relay in the DIY idle control can ground through the starter switch. The small current the idle control relay draws won't budge the starter solenoid.

 

i've been looking into it and ebay has the ford Aux idle controls for 150 wayy easier

 

Is that the panel that mounts under the dash with the ford button? I drove at least 6 wreckers (F450 OBS) that those didn't work since new.

 

the emergency brake must be set for aic to work.

 

We used to have a mod around here known as the HIM or high idle mod. Its real simple and cheap. You start your truck and take your snow scraper and wedge it against the pedal. I personally have a snow scraper/ brush and I put one end against the pedal and the other under thedge of the enter seat/ console and adjst the pressure of pushing down on the seat back to increase the idle to where I want it. Works great, dirt cheap. usually set the idle around 1200 rpm and then if you modify your EBPV you can close it manually and it will work al little faster. Others did the mod by wedging a screwdriver behind the pedal to the same effect.

 

Uh ya I know. still didn't work most of the time.
