What is an AIC??

[Blue01F250]

Aux Idle Control... I saw this on one of the other diesel forums -- what does it do???

[Stroked95]

maintains a specific rpm. Auxilary Idle Controller(AIC), I think it was for trucks with PTO.

[ABOBB]

It is a add on for 7.3 powered trucks that allows the user to control the idle.

It's used mostly to raise the idle for when the truck will spend long periods idling, or when a pto is used.

[Blue01F250]

and PTO (power transfer ?? ) would be some type of equipment that is going to use the truck power?

[ABOBB]

Yes... PTO stands for Power Take Off... it is usually used to drive a hydraulic pump for a wet kit, or some similar application.

[Blue01F250]

Well, I do'nt think i'd be needing either of those... lol just coudln't find what it was so wanted to ask!

When I drove trucks we used the PTO for our dump beds it would raise the idle of the truck to power the hydraulic pump better.

thats what we use on all our wreckers and flatbeds ... speeds up theengine rpm so the hydraulic pump(driven off the tranny)pumps the fluid quicker making the hydraulics work faster


its available for the 7.3 and the 6.0 we have both one in our 1999 F550 7.3 and one in our 2003 F550 6.0L..life would suck with out them for what I do

[Blue01F250]

ah - gotcha... I guess I knew what they were but never knew what they were called Thanks for all the quick answers! And now it will show up in a search if someone else has any questions!

(I did a search and it didn't show up so I decided to ask )

I have this set-up in my truck, I have never noticed a PTO and I don't have anything that would be powered by one. So my question is could you get this without having a PTO?
