Envious... We have a '13 Eco that has towed heavy flawlessly in 7-10,000 ft. elevations for the past 5+years.Fans always kicked in if needed at 224 or 225. They ...Ford.. reflashed ours transmission the first part of July.The first tow after that was 1st part of August up to one of 2 of our favorite campgrounds. I notice the temps were higher but didn't think much of it at the time. DW & I are on a 5,000 mile jaunt up to the Northwest part of the country and have had several times where the temps have gotten up in the 230's range & tranny temps up in the 220's when I have put the boost to it.. For what ever reason the the high temp fans are not kicking in like they use to. I know it has something to do with that reflash. It or they changed or deleted the signal for the sensor to kick on the high temp fans. I'm going to find a Ford dealership & see if I can get some answers. Finally figured out how to keep the temps from going over 228 when pulling a 6% grade for 5 or 6 miles. But that relash change it.
- Ok I'm glad I'm not imagining things here! Yeah I find it weird they changed it to run hotter as well. I bet for emissions and MPG reasons.. but all more of a reason to stay tuned lol. If you find anything out please post it up! I know masshole sent me a PM and showed that his fans should hit high at 225. Do you have a tuning device that you can pull the stock file? I'm sure someone can dissect it and take a look.
