high idle

I know the truck seems to sometimes go into a sort of high idle on its own but I was wondering if the dealer can enable a high idle function that we can turn on and off ourselves?

nxtdiesel, the short answer is yes! There are many discussions here on FTE that talk to that. I'm really not the expert here even though I have high idle enabled on my truck. Do you have up fitter switches? It would be easier if you did. When I purchased my truck I asked the dealer to enable the high idle. The dealer did mine at no charge. I think the reason was I asked for it before I took possession though. It's not just a computer change, wires have to be installed, and run into your passenger side kick panel. I hope the attachment works here as well as it will give you more information. I would also search this forum for additional information. I hope this helps.

okay, thanks! I have to take my truck in next week for the service engine soon light being on and I thought I would see if they could enable the high idle if it was a simple computer change. Since it's more involved I probably won't worry about it. Thanks again for the help.

It's a super simple job that isnt all that difficult. Especially if you buy an aftermarket plug and play kit online. A quick google search for "Ford High Idle Kit" should do it. Costs about $100. Having a dealer do it will cost $2-300. If you have general mechanical and electrical knowledge, do a search in this forum. Plenty of threads discussing how to DIY...cost of about $5 and up to a couple hours of time max. Most of that time is spent trying to find the pass thru wires. If I had to do another one, I'll bet I could do it in under 30 minutes.

With my old 6.0 I had to lay on the floorboard and reach up behind the dash to do the splicing. They wised up and put the circuit on a removable pigtail so you can solder in your resistor on the bench and then plug it back into the truck. That makes it easy. If I had to lay on the floorboard and try soldering under there I don’t think I’d have even bothered doing it.

I like this one as you can change RPM'S for your liking.

I’m liking the BD Diesel high idle kit. The others seem to require the ignition to be cycled to re-engage high idle. The BD Diesel kit doesn’t and the RPM is adjustable.

This is installed in all of our fleet trucks, excellent quality and very easy install. I also have it in all my personal trucks.

Looks good. If/when I go with that kit, I'm thinking about tucking the **** in the upper glove box area so it's concealed. I don't run a PTO so it'd be a set and forget type of thing for me, I may play around with it from time to time but it's not something that would be adjusted regularly.

I also installed one of these yesterday. Super easy plug and play solution. You can make your own for much cheaper but I just wanted a plug and play solution that works and this kit delivers. The build quality is excellent and the harness uses OEM style connectors and good sleeving. The lazer cut stainless mounting bracket for the switch/pot is a bonus if you decide to use it Very high quality.

Having the ability to select the RPM is very nice as well.

Bottom line is that it just works and works great!

If you do that remember you will have to cycle the ignition. Making the switch easy to access is key to being able to go on/off without having to cycle the ignition.

I'm not following you there. I thought the whole point of the BD kit was you didn't have to cycle the ignition, you just had to meet the parameters (not moving, park or neutral, parking brake on and engine above a certain temp). I'd mount the **** where I could still reach and access it, it just wouldn't be visible, it'd be inside the upper glove box.

Yes you need to meet the parameters, however if you disengage the high idle you can use the BD switch to cycle on and off which will then allow the high idle to resume. Without cycling the switch you would be forced to cycle the ignition to be able to resume the high idle. The same way the 12v solutions kit is setup. I use the high idle all day so every time I move the truck up 20' at the job site I just set the parking brake again and cycle the BD switch. Without the switch you would have to turn the engine on and off which gets annoying.

Gotcha, thanks for the clarification. I thought I had misread how the kit works. My switch will be accessible, just not overly convenient but my use will be much different than yours. Mostly cold starts and warm ups. The other times I'd use it, it wouldn't be bad to just reach across the cab and cycle the switch.

Thanks
