4-25hp Heavy Tow
5-40hp Moderate Tow
6-65hp Standard Tow

The spec sheet shows:
1-Stock
2-Fuel Sipper
3-25hp Heavy Tow
4-40hp Moderate Tow
5-65hp Standard Tow

Can I get a clarification on this. It sound like position 2 is a little quieter (Whisper Mode) but it doesn't seem like a big difference. Is it possible that this position did not get put on? I can't answer about what went where on the chip. Does your chip actually HAVE 6 positions on it? All trucks seem to react differently to the Whisper Mode tuning. However, since you have a single shot injector truck, the Whisper Mode should make a really big difference when setup right for YOUR truck.

Now concerning the different Tow modes. What is considered heavy, moderate and standard? What is the reason for less hp on a heavy tow? Heavy would be in the neighborhood of 13K lbs. or more. Moderate usually constitutes a load of 8K to 12K. Light tow would be up to 6-8K lbs. The truth of the matter is, depending on the truck, the driving style, and the maximum EGT you can sustain or control dictates how much you can (or should) tow with each setting. The reason that the heavy tow program is "worth" a lot less power rating is that with a diesel powerplant, more power usually ALWAYS means more heat (EGT). Besides, towing a 15K load with a light duty truck with 300+ HP (designed for 215 HP) will kill drivetrain components in a hurry.I will use the truck for pulling a 30ft 5th wheel almost exclusively. Unless I'm on the beach or just around the house.

So what would the best hp setting and will that vary if I am in mountains (Va and WVa) or in the flats like eastern Va and NC? You will have to determine that. Like I stated before, there are a lot of variables and you need to drive each tune and decide which one gets the job done the best without skyrocketing EGT.

I did go for a quick spin and WOW the 65 hp really gets up and goes and I noticed the shift points changed quite a bit and the response on the shift was much smoother. Almost wanted me to hook up the camper just to see how it would run (gotta wait a couple more weeks though).

Lastly in the instructions it says that is is discouraged that you shift on the fly while under load. I understand that to mean whille towing, correct? Yep, for a couple reasons. First is that you're INSTANTLY changing the power level. Under certain conditions, this can shock the drivetrain and cause damage. Secondly, each tune has a lot of different engine control maps that dictate fueling rate and injection timing. The way the PCM and chip work, address lookups in the chip may be slightly delayed or skewed for a split second causing at minimum a "bump" or at worst, damage. Always TRY to allow a coast/decel or back off of the accelerator pedal before switching tunes.

Thanks a bunch,

here is a copy and paste from the tow settings thread in the Phoenix forum
DJ,

It breaks down like this:

* 25hp - Over 20,000 GCWR (all terrain)
* 40hp - 16,000 to 20,000 GCWR (all terrain)
* 65hp - 12,000 to 16,000 GCWR (all terrain), 16,000 to 20,000 GCWR (flat terrain)
* 80hp - 8,000 to 12,000 GCWR (all terrain), 12,000 to 16,000 GCWR (flat terrain)
* 100hp - 8,000 to 12,000 GCWR (flat terrain)
* 120hp - Not Recommended
* 140hp - Not Recommended


Keep in mind that files designated as "Tow" are designed specifically for the needs of towing (shift strategies, pressures, lockup, fuel curves, injection timing) while "Performance" programs are handled quite a bit differently.

Hope that helps.

Cody, your last post was excellent! It answered quite a few questions that were in the back of my mind regarding HP and towing and clarified some other points, such as the relationship between HP and EGT.

Thanks!

I am confused probably as much as the guy that started this thread. Are we talking gassers or diesels?

This one's about diesels, Lars. There's a lot that is VERY different about them, isn't there?

I was posting in reply to bukbugy's question and his is a PSD.... though th
OP was asking about gassers

[Jackpine]

You're right, of course! We DID change horses in the middle of the river, didn't we?

Sorry to confuse you guys. I was so excited about getting my PHP Phoenix module that I stuck my questions in the thread for gassers.
An yes there is a difference between the two especially with this module now
Thanks to all those who responded and I'm looking forward to hitching up to the 5th wheel

You knows guys, I have a pretty good grasp on things some of the time but I was just trying to figure out "when did ford put a diesel in a 97-03 f150?". I was just pointing out that the poor guy who started this thread is going to be saying "what in the world?"

Oh well at least I'm not jbrew or rockpick! (Yet?)LOL

Yeah, i am reading all this great information.. yet, it's not really helping me.. But if it helps others, that's great. Just trying to get some feedback if anyone with a gasser in a F150 tried this out and liked. I read one report on F150ONLINE from a guy who gave it a favorable vote, just trying to poll others...

No worries, we are all learning about Phoenix modules!
