HUGE Load with 210 Heavy Tow Tune

[BIGBLUE08]

Well guys i have been putting this tune to the test the last few weeks while we are puttin up hay I have been hauling tractors around everywhere across big steep grade mountains up huge ridges through fields and this tune has works pretty well except for my tranny heats up above 200 a lot and today with the load in the picture i went over a big steep winding ridge road and it got to 228 i got a lil nervous but everything seems fine. This tune has all kinds of power and its def worth trying. Thanks to Spartan for such GREAAATT TUNES.....

thats one heavy load

How far were you going with that?

I probably would have just driven the tractor?

That is good stuff!

[Spatel23]

wow......i think you may need a 450!

Don't worry about 228*, a stock truck will do that while towing. I towed a bumper pull trailer to OK City from South Texas and I was getting temps, of around 235 regularly while running stock. My trailer wasn't as heavy as yours either. It was well within the weight limits of my F350 dually, and I was getting transmission temps of over 230, and oil temps around 230 as well.

what are safe temps for the trans and oil temp in our 6.4's

I don't know, but that is when I started to back off. I wasn't doing anything radical, I was just towing through some slight hills (near FT Worth on I35) at a reasonable highway speed (70-75), with an empty trailer (~6000 lbs). I was running stock since I had just got my truck back from the dealer before the trip, and didn't have time to reinstall my goodies. I did have my dashdaq though. That is how I found out that it was getting hotter than I really liked. The coolant temp was getting to 228* too, and I found out that the fan kicks on at 224* every time.

I wasn't doing anything that Joe Schmoe Ford owner wouldn't do if they didn't have any clue about such things. I figured I was completely safe, since I was running stock. I figured that Ford would have designed the computer to not allow any operation that would harm the truck. And it didn't, but I am wondering what the upper limits of safety are when it comes to temperatures. I know that it will go into limp mode during severe overheating. I don't know what severe over heating in terms of actual temperatures though. I didn't have a real coolant temp gauge on my F450 when it did that, so I don't know.

If you were at 235 for long your fluid is cooked

What model tractor is that? Im betting he's not as heavy as he looks
