high idle

[larrygranny1]

new to this forum, my F250 has always idled at 1200 rpm. Just wondering if everyone has that high of a idle? 08 F250, stock, 6000plus miles, locale i'm getting 15.8, light right foot, mixed driving conditions, highway 20.4 @70, locked in. have not noticed any regen...could the higher idle be the answer to long ildes in traffic??????? After reading so many different web sites about htis 6.4 I'm beginning to think I may have finally gotten " the good one off the production line" Just wondering about the high idle........could it be the difference????

just to let you know if you care, bought this to tow my Trailer to 23 states, starting in Feb, golf in each one, collect the logo ball, completing collecting all 50 balls. On a couple of practice pulls, averaged 13.8 at 65, locked in. Pulling 6300, Jayco. Previous tow vehicale was 05 F150, Hyperteched, average 9.8 at 65 locked in

Honestly ive never noticed one consistantly idleing that high....but i go by the "if it aint broke dont fix it" theory. With the fuel economy your getting and the fact that its running good....i wouldnt mess with it...

Has anybody tried changing there's with the high idle mod?

Looks like he might have gotten a truck with it already installed....

Could this be the answer to our mileage issues?

That is where mine idles during Reg., I would'nt bother it what so ever if you like the milage and power you are getting! Sounds like you have a good one!

I just wanted to know if it was normal. seems like everyone is always going into regen. would be interesting for someone who knows how to work on these to increase their idle to 1250 and see if they get a difference and post it. perhaps the higher idle on mine is the reason i don't regen as much or all. it is burning everything when i idle. i don't know know much about whats under the hood. I normally buy new every 18 months, but i think this one is a keeper. I'm very pleased with the performance. In Feb when I start pulling the TT, to 23 states I'll post and let everyone know how it goes, if your interested.

The high idle mod is posted in the 6.4 tech files on the forum...
Its usually done to run equipment from the truck...

I still haven't really tested what mpg i am getting yet... Going to fill up today to find out...

I almost want to do this to see if there is a difference...

When mine goes into regen it kicks upto 1200rpm and when it's cold engine it goes up to about 1000rpm to warm up the engine.To me it sounds normal.

Is it me... or is he always idling high??????

That would then be the high idle mod.... Which can be done from the factory for running accessories off the driveline...

I am pretty sure he is not just talking about when he is warming up, but at all times....
