My dad's 2005 F150

Post by ELVATO » Fri Jul 27, 2007 10:56 pm

My dad got a "new" truck for work today. It's a 2005 F150, extended cab. It has a 4.6 motor. As soon as I got home, I went to work with a tune. Not that there is much to it :lol:

The first thing I noticed when I started up the truck with the tune on was the lack of delay between pressing the gas pedal and the "whistle" from the motor, aka better throttle response. Told my dad to drive it down the street to see if he noticed any difference. He came back and said he noted it "livelier."

Also noticed that communication between the interface and the truck was alot faster than with my 03 Expedition. It was done getting the stock file, and copying the tune in around a minute.

So after loading the tune, I decided to take it for a test run with my G-Timer. Unfortunately, my mom decided to come along, which is why I could only measure 0-60. She was freaking out because I was doing 60 on an empty, uninhabited street :roll: Oh well, here are the results. Sorry I couldn't do a quarter mile. :(
87 Octane Tune, 200+ RPM per shift, firm shift
0-60: 11.15 sec
0-50: 8.02 sec
0-40: 5.28 sec
0-30: 3.53 sec
0-20: 1.82 sec
0-10: 0.50 sec
1000 ft: ----
1/8 mile: 11.55 sec/60.1 mph
330 ft: 7.43 sec
60 ft: 2.52 sec

Stock
0-60: 11.50 sec
0-50: 8.42 sec
0-40: 5.63 sec
0-30: 3.85 sec
0-20: 2.13 sec
0-10: 0.65 sec
1000 ft: ----
1/8 mile: 11.85 sec/59.9
330 ft: 7.70 sec
60 ft: 2.70 sec

As a side note, the very first run I did was with the tune and the AC on. I did 0-60 in 11.50 :lol:

Some observations/notes. Even though I had the shift at firm, the truck shifted the same. :?: Don't know what happened there. Also, since the truck doesn't have a tachometer :x I couldn't tell if the truck really shifted at 200+ RPM over stock at WOT. In case it's relavent, the coputer code was HEV0. I'd love to see what a 93 tune would do, but my dad only gets 87 gas. :| Also, I'm sure the truck could use a CAI.

Well that's it for now. :)

Had to go in town for something, so this time I took the truck instead of my "ride." Decided this was another oppurtunity for me to see the the program in effect. I went into town stock, came back with a slightly different tune. This time, I went with race shift firmness and 300+ RPM. These are the things I've noticed.

-It still doesn't change the shift firmness at all. Even with the race setting, the shifts were as soft as stock.
-Even though there was a lack of a tach (come on Ford, I thought everyone had these stock :roll: ) it does seem that the thing is shifting past the previous rev limit.
-With or without the tune installed, the thing drives like crap. Anytime I want to accelerate, the thing will downshift. With the tune installed, you need to push the gas further in for it to downshift, but still, it's enough to be annoying. Maybe I'm just spoiled with Matt's work on my car's shifting. :lol:
-I was going to see if the speed limiter had been removed, but I ran out of road. Again, this was on an empty, uninhabited street.

How different are the 4.6's from my 2003 Expedition and my dad's 05 F150, other than the fact I have a CAI and a 93 tune. It seems like the one in mine pulls alot harder. The F150 seems...."gutless" as some at f150online say. Is there a huge weight difference?

As a side, unrelated note/question/rant: Why does the Expedition seem safer/more stable at higher speeds than the F150? The Expedition is higher off the ground by a couple inches, yet I can take tighter turns, "handle" better at higher speeds, etc. In the F150, I'm going 60-70 and it seems "playful." Is it because the Expedition has more lower weight? Bleh, I guess all I can do is wonder

The 3 valve motors like the 05 in question lost a little torque down low so ford put in a higher stall converter in to make it just a bit less gutless. It does a lot of converter locking and unlocking that is sometimes counter-productive. I hope to get my hands on a 3v test vehicle soon to optomize the shifting and lockups like I have done on the 2 valve stuff.

Oh and the IRS and coilovers on the 03 and newer Expeditions really make it handle nice over the older ones and the trucks with the solid rear axles.

Have you considered a FTVB to firm up the shifts?

FTVB? Is that a mechanical way of firming up the shifts? I don't really need the truck tuned. Neither does my dad. I was just testing it out; trying to see how much it "affected" it. Also, just wondering why the shifts won't firm up like it has in the two other cars I've tested (my Expedition and my roommate's 01 Mustang.)

So why did Ford switch over to 3V? More HP? And yea, I'd forgotten about the IRS. Guess it really helps :lol:

They needed to get closer to Chevy's HP/Cubic Inch numbers that the LSx motors are making.... the funny thing is that the Chevy motors are much lower tech pushrod motors and don't have IMRCs (mechanical butterfly that blocks off one intake port for more velocity at low RPMs) (not needed on a 2 valved motor) or variable cam timing and still make amazing power and torque.

the reason it wont shift firm is cause of the template on the new 05s i have the same problem except i found out the hard way what you have to do is work it out with the delta force or so thats what i was told by my sniper guru pat lol :ugeek: also like in the 97s which i tune alot everything works bad [I have a potty mouth] except in factory ecu it cuts at 90 and with the sniper or the delta it cuts at 95 and if we turn off the speedo code the things goes biserk any of you have had this problems??? and what are the settings you guys use to tune trucks i havent had a chance to tune a mustang

You haven't tuned your Mustang? What is it, a 97 GT?
