High idle

Does the 2001 PSD have the option to add a high Idle switch option?

Yes, there are several ways of accomplishing it. You can wire up a toggle switch, install an AIC, or buy a tuner with a high idle mode.
There is also a factory high idle that kicks in on the cold mornings.

I did mine with a potentiometer and resistor wired into the wires on the fuel pedal. I have seen alot of the AIC on ebay lately for about $100 bucks...If you can deal with ebay.

Why the resistor if you have the pot?

To keep a idiot from over reving it.

From what i read the pot is to sensitive by its lonesome. The resister makes the pot less sensitive.

Without the resistor you just touch the **** and it could change 500 rpm lets say.

That is how i understood it. Correct me if i am wrong in my thinking because it is my next mod to tackle.

Makes sense, I just wasn't sure why the resistor was needed since a pot is basically a variable resistor itself.
I vote for AIC install myself, but I didn't pay any $100 for mine
AIC install
AIC e-brake bypass switch

When I did the mod a couple years ago it didn't work very well. It seemed the idle would vary drastically with differences in ambient air temperature. I have a feeling the temp differences were effecting the resistance of the resistor. I ended up taking it out after about a month...

Thanks for all the info everyone. Im going to have to see if its really that important to me. I know one of the guys at my firehouse has a new powerstroke and his has a wire that already stubbed out and just hooked it up to an uplifter switch. Thanks again, Jason
