I'm trying to find a chip/programmer for my mom's 2004 Expedition 5.4L. I haven't been successful yet as I'm only finding programmers for the new f150. Will programmers for the new f150 work, or is the 04 Expedition using the 'older' version of the 5.4L?
The main reason for the programmer is that she intends to purchase a 25ft travel travel (6-7k lbs loaded), and I'm looking for something to;
a) firm up the shifts and raise shift points,
b) increase performance
c) display engine oil temp, tranny temp, etc.
I found the Edge products Evolution that does this and more for the F150 but no idea if it works for the expedition, I sent an email.
Does anyone on here have a programmer on a new body style expedition, and does anyone tow regularly? Any suggests on upgrades for the Expedition? It is the 5.4L as mentioned with the 'optional' tow package with tow rating of 8650lbs. Any obvious (or not so obvious) weak points that should be addressed prior to towing a travel trailer? First thing to do is replace the crappy continentals with an LT tire.
Thanks for the help!

edit; Saw the superchips programmer after posting, but found this in the comments...
# Adjust Shift Points, F-150 & Mk LT only
# Enhance Shift Firmness, F-150 & Mk LT only
Not much good to me in that case, I think

 

Hmm, 17 views, no ideas eh?
Here is the response from Edge Products
So no ideas on a tuner for the 04 that will firm up shifts?

I've been very happy with the Diablosport Predator on our 2000 Expy.

 

I also have the Diablo Sport Predator. I would definately look into this Tuner, it will do most of the things you listed except display temps of tranny and engine.

 

I would just call a couple of the Tuner Reps. and ask them what they have to offer. I just checked a couple of different brands and you are right, the "04 Expy seems to be kinda of left out. I would call superchips or diablosport and ask them.

 

If all else fails you could go and have a custom chip done, they can address your shift points, tc lockup and any performance tweeks you want done.

 

my tuner uses the xcal II. i have it for my truck, thought there is a little more involved in my pcm than just towing. pm me if interested in his info.

 

I replaced my 1998 XLT 4X4 with a 2004 EB 4x4 with HD tow package this January. I have the 5.4L engine with 3.73 axle ratio. I tow a 7,000# Rockwood TT (29' long). I just returned from a 2 week trip from Chicago to Glacier Park Montana hauling the trailer and 3 adults and our Dachsi. No mods to the truck yet but it performed perfectly. Towed up the mountains with no problems. Averaged 11.2 MPG until the way home when a 20 MPH headwind all through Wyoming and South Dakota cut it to 9.8 MPG. Gasoline prices along I-90 were around $2.80 per gallon. The trailer tows fine with the Expy as-is. Good luck and happy towing.
