Long story, and its been covered here ad nauseam, but my driving needs make my Jeep get a little hotter than I like. Not overheating, but when working HARD it will get a little over the 1/2 mark before the cooling fan finally does its work.
(Before someone says something is wrong, it's not. It's been totally gone through by two different dealers and STAR cases opened. I just work it hard climbing hills and what I see is normal given the conditions).
After a little research, I found out why. In the 2014's, the cooling fan kicks on at low speed at about 226 degrees and doesn't reach full on high speed until high 230's. I don't like that. So I'd like to drop the temps at which the fan kicks on.
I know I can do that with a Superchips. I have NO interest in messing with any other setting other than the fan engage temps. Has anyone else done this? Please share with me your experience. Did you have to adjust both the high and low speed fan temps? Or does setting the low speed fan engage to a lower temp automatically bring down the high speen fan temp too? I called Superchips and the guy had no idea what I was talking about. It wasn't very reassuring. Any help with specific experience is welcome. Thanks.
This is my first replay in this forum.
I am in the same boat, I got diablosport trinity 1000 and had the same issue I do have 2014 rubicon auto and the temp reach 219-230 on the high way most of the time when ambient temp is 80+.
I have tried to play with fan setting on my diablosport and it does load the setting but it doesn't take an affect on the PCM.
I called diablosport and explained my situation several time and finally the admitted the 2014 jk has different software than the 2013.
I am still waiting diablosport to solve the problem for 2 weeks now and haven't got any call back from them.
So diablosport doesn't work with 2014.
Many feature doesn't work.
Fog lights feature not working
Fan adjustment not working
Throttle boost not working.
78 octane mpg boost which is the only one I have tried it does not work.
I called superchips and asked the about flashpaq fan adjustment for 2014 and the rep have no idea what I am talking about. Then I asked him if he can call thw engineering department to confirm if the flashpaq will work with 2014 and then I got the answer!!
Flashpaq fan adjustment does not work with 2014.
I have a superchips programmer, and while I have never adjusted my fan speeds, I did notice it in the menus. There are separate adjustments for high and low speed fan control. I'm not sure how much adjustment you have, because like I said, I've never actually adjusted it.
I'm considering reloading the 93 octane tune, so if you'd like, I can take pictures of the menu when I hook the tuner back up.
I dont have a full programmer, but my Aeroforce gauge has a setting to force the fan to high or low, but it doesnt work at all. Something has changed in the 2014's fan programming that none of the 2012-13 stuff works. I bet somebody will get it figured out though.
The fact is until 2013 most of chrysler products has two fan sitting or 3 fan sitting low, mid, high.
the 2014 use pulse width modulation fan controller which is totally different from earlier years model. The new system is work very complex it does read ambient temp and transmission oil temp for auto trans and coolant temp also the condenser pressure then the controller will decide the fan speed.
No wonder why my 14 seems to run hotter under load than my 12! Thanks for that info. Two dealers couldn't even explain that to me. Someone figure out a fix please... I don't like seeing temps that high and my gauge over half!
This explains as to why my 2013 temp gauge, doesn't go above the 1/2 mark. When I shot the top tank temp, it was 207 degrees, and 113 ambient outside.
So the change then took place in 2014, and that explains some of these high temps that you are seeing.
This is very interesting.......
Maybe the FEDS, are mandating better emission control!!!!
Yep. I climbed the same hills in my 12 and never saw it get over 1/2 on the dummy gauge. This 14 does it all the time! Probably because Jeep is using the exact same gauge/sending unit, yet it now runs hotter. Scared the hell out of me at first. I've sorta gotten used to it now, but sure don't like it!
