Re: High idle switch on 2011

LOL, see this is what I get for going from memory. I suppose the ones I'm trying to remember must have had a cable end on them 'cause youre totally right.

Let us know what you end up with. I've been thinking about this too.

Re: High idle switch on 2011

Wonder if you can fool the computer into thinking the engine is cold. I read somewhere where someone with a gas F-250 added resistance to one of the temp sensors to fool the EEC into thinking the engine was cold, causing high idle.

Re: High idle switch on 2011

Yeah but that'd only get you a couple hundred RPM. Cold start is only like 1200RPM. What if you really want to run it up say while winching or jump starting; it would be nice to run it up to 2k or so.

Re: High idle switch on 2011

Now you have me thinking about building a potentiometer controlled RC servo using an Arduino. I wonder if the servo could be linked into the TB.

Wouldnt a block heater aid in heating the truck up faster??

Re: High idle switch on 2011

First version is done! I decided to go with more of a hand throttle for now because that's what I had the parts for lying around. I have friction shifters coming to make it more of a high idle device.

I used a few blocks (pulleys) that I had from my sailboat and an old mountain bike brake lever and cable assembly. I welded up a bracket that screws into the firewall that holds the bike cable and the bottom block. On the pedal I bolted an angle bracket on with a pulley attached. I used small no stretch line for the intricate part and steel cable for the rest.

It works perfectly. I can loosen the adjusting barrel on the bike brake just like you would do to adjust your brakes to increase the idle. I can also use it as a hand throttle for hill starts and such. It is a bit of a learning curve to drive with but easy once you practice.





When the pedal is used normally the pulleys just pass right by each other and have no effect on the operation of anything.

Let me know what you think!

Re: High idle switch on 2011

Only part that seems strange is the brake lever on a manual shifter... That doesnt get in the way at all?! I know there is more room than pics tend to show I guess!

Re: High idle switch on 2011

I think it's rad! As soon as I get some free time I'll be copying you on this. Could you hide the cable in the shift boot and then run it through the console to the peddle? I think it would make it look a little cleaner. Other than that this is an awesome idea and great execution IMHO.

Re: High idle switch on 2011

Random thought....

Is it bad to have the gas depressed when the vehicle is off? I take it as no since its drive-by-wire.

You could hook it to the ebrake. I know this may negate the "emergency' part, but it would give you a completely hidden higher idle when parked and ebrake on....
