High idle switch on 2011

Does anyone know how to install a high idle switch on a 2011 fj 6mt? I live in Vermont and would really like one to aid in faster warm up times and the extra alternator output such as winching. I would realistically like to be able to set the idle about 1800 rpm or so. If their was a way to wire a potentiometer into the gas pedal to mimic the output that would be ideal.

Any ideas?

thanks-
Matt

I don't think so. It is all drive by wire. A few of us have wanted to put in a thumb throttle but can't figure out how to do it with all of the computers.

Re: High idle switch on 2011

Any electrical engineers on here ? maybe someone has an oscilloscope and can read the output that the petal is making. or maybe there is a better solution such as something that screws in to hold the pedal down or pull it?

"High Idle" on a Humvee is a pull cable that mounts to the backside of the accelerator linkage. Not going to get much simpler than that

Re: High idle switch on 2011

^^So I could do a thumb throttle like that as well?

Re: High idle switch on 2011

I have seen ambulance auxiliary idle control modules on Ford Powerstrokes before. In fact my friend had one on his old 7.3L. He used it to warm up his truck faster in the mornings. I did some searching but was not able to find anything for a Toyota. But you'd think somebody would make one.

I don't see why not. You just need a solid cable that you can push/pull and attach to the accelerator linkage, then (depending on install, like from the back of the accelerator) when you pull the cable you pull the pedal to the floor and accelerate and when you push it back in the pedal rises and you decelerate.

Humvee's use something like this positive lock cable.

Teleflex

Re: High idle switch on 2011

I am now thinking of using something similar to what jeeps use. A friction shifter from a mountain bike to hold the throttle down. also using a pulley to be able to get the pull in the correct direction. I will be using bike shifter cable.

something similar to this: http://i776.photobucket.com/albums/y...ottleCable.jpg

thoughts?

I am the only one driving my fj ever (gf cant drive stick) so I'm not worried about someone else messing with it.

Re: High idle switch on 2011

If you use a solid center cable (not a flimsy stranded center cable like a bike brake cable) then you can simply loop it and you won't have to monkey with a pulley. Solid will also allow you to push the cable in to turn it off if the spring return is not strong enough to over come the friction of the cable. Solid is safer IMO

Re: High idle switch on 2011

But how will the solid cable disengage so i can use the throttle regularly? the benefit to the bike cable is that it will just coil when i drive and not get tangled.
The friction issue is not a concern, many people have done this on trucks and jeeps for years the same way. they just connect to the carb or throttle body instead of the pedal
