That is true. But my truck has problems with idling up on cold days currently. I've got a switch on order. I think it would be a cool thing to do but instead of making it mechanical by rotation the dial. Wouldn't it almost be easier to put a electronic switch board that could have set times that can be setup to turn the high idle on every time the truck starts and is left in idle state for more that 2 minutes. Then it high idles. I know it's a little.outside of the box which is why I asked if anybody has done it. It would also be cool if the electronic board could recieve Bluetooth and change to whatever setting you choose from your phone when doing remote start.
