Settings/ Alarms

[svt2205]

I'll make the adjustment to check out the CHT. It's all of 7 degrees out there this morning (still dark). Is this something that can be changed while it's this cold out? You guys did a good job of educating me on the "tricks" of programing changes when it's cold. (warm things up and be sure battery is fully charged).

I've learned more regarding the hot running and all. I've now run hot 2 additional times. Unfortunately, these were without the plow. So, something's going on. Both times happened while idling. I did pull 2 codes (no CEL) (codes have been cleared). P0483 Fan Performance and P0528 Fan Speed Sensor Circuit No Signal. I've not found anything useful from Google on these. I did find stuff for folks with the 6.0 PSD and this code. As well as a reference to a TSB (can't located a copy of it) for a 2008 Super Duty. Apparently if you plow with 2008 SD without the factory plow prep package, you may get this code. More research is necessary on this one. I don't know if the codes were recorded while plowing or after.

Regarding the performance vs tow tune. I've got ample power in either tune to plow. Heck, Ford gave me more then enough in it's stock form. But I run the performance tune because the shifting seems better (to me). In the tow, it seems like it hangs in low gears longer (good thing for towing) but without a tow load, it just doesn't feel right (again, to me). I guess I could adjust something, but it's much easier to leave Bill's handy work as it is. Plus, I'm sure I don't know what I'm doing.

You mentioned "comm gear" what's that?

Thanks again for your help. It's greatly appreciated.

Comm Gear is just one of the PIDs you can monitor. It shows what gear you're in and if the torque converter is locked or unlocked.

I wonder if you have a faulty fan speed sensor, or a broken wire to it? If the fluid clutch for the fan is not locking up when the engine gets hot, you would get overheating. Isn't your truck still under warranty? I'd get this checked out if I were you.

And, changing the display should not be subject to temperature problems. If you see the display normally, all you're doing is changing what the Gryphon is showing you. I believe you can do that with the engine running too, since it doesn't involve the PCM.

I still can't help feeling a tow tune is better for plowing than a performance tune. One thing about a tow tune is that it is slightly richer, which helps to keep engine temps lower. I'd be happy if others, like Lars or Bill would add their opinions here on this, because I could be totally out to lunch in my opinion.

Yourt fan isn't old school anymore.
The fans on 07+ are now electronically controlled.
So if its under warranty get it in and have them take a look at it.
Remember to put your truck back to stock and remove gryphon from truck.

Good catch, Lars! I'd totally forgotten that small fact (or maybe I thought it changed with 08's).

It maybe in correlation to the head change also.
So if you have black cop boots on the spark plugs you may have an old school fan. But if you have the brown cop boots aka revised heads you will have the electronically controlled fan.
The jury is still out because I'm still researching this correlation.

No warranty left on my 07. After "running too hot" session number 2, I called my local dealer and asked if they had a fan clutch. Of course, they did not, but when the parts guy came back saying it was $323. FWIW, NAPA sells a replacement for$ 400. I knew the good old days of simple fan clutches were over.

I'm on my own with this one. I'll be looking at the electrical side of the fan speed sensor this weekend (if it warms up enough). But I find it very interesting that I get hot both with or without my plow on. But I only get codes when the plow is on. These 2 codes P0483 and P0528 don't trigger the CEL. So, I'm thinking they probably showed up last winter while plowing too. I didn't have a Gryphon then.

I'm going to try plowing with the tow tune and stock tunes next time it snows. Just to see if the codes return. (all that's needed is a few miles of driving with the plow on to bring them back).

Thanks for your suggestions.

For that kind of money you could go e-fans.
Troyer sells a kit, at a good price too.
The only problem is that the one code for the fan will still be there if the efans are installed.
Just a thought.

Here's the link to the kit:

Thanks. Looks like I can get the fan clutch at an online dealer for a little under 200. I've been contemplating replacing this truck anyways, so this may just be the motivation I need. But then again, no payment is kind of nice too.
