SCT Performance
Hi All ... It's been awhile since I've been here. Hope you'll let me back.
I wanted to get some feedback on some mods that I did to my 04 F350 Lariat CC DRW. I installed the SCT Excalibrator II and a 4" dual Mangaflow exhaust from the turbo back without the cat. The tuner is generally installed to the street tune with the TC locked up at CT and TC lockup in 1-3, Here's what I've noticed:
1. I cannot drive the truck daily in the performance tune. When the truck is cold, the transmission shifts so hard that I think that the truck is coming apart. It has set a transmission slip code in the performance tune under "normal" driving conditions.
2. It doesn't feel like the converter locks up in 1-3.
3. EGT's dropped by 20% at WOT after the exhaust install
Please don't take any of these items as complaints. I am 98.5% satisfied with the mods. I'm an engineer and I don't like unanswered questions!

I have yet to install my SCT but have noticed the same hard shifts when my truck is cold. When I installed the 4" turbo back MBRP they seem to be even a little more crisp, for lack of a better word. I baby my truck until it get warmed up so no real big deal to me. Just wondering what it will be like once I install the tuner.
I have not installed the tuner yet since the book warns about having a low battery, disconnecting fuel/fan fuses, even possibly connecting a battery charger. I assume this is all CYA stuff from SCT, but makes me wonder how long it takes to re-flash the truck.

All of that stuff is for the gassers. You do not have to pull the fuses and stuff. Just plug it in and program away... When I don't have a cold fix in a tune it will just be very touch throttle and wierd shifting until it warms up.

If you haven't already done so, you should update your tuner. It contains fixes to most of the problems diesel owners are experiencing. If you don't like what's going on after the update, Ryan, Mike or one of the other guys can send you the previous version of the file you need. Make sure and return your truck to stock before you update.

Well if you have the canned SCT tunes I think they can put the cold fix in but I know that custom tuners can. They put some code in the tunes and while in my experience it tones down the tune a little it helps a lot with the shifting. Trust me it is worth it if you can run a little toned down street or tow tune during the real cold times. If you need to know a specific tuner to call send me a PM or email and I will give you my tuners name and number. FYI.. This code is made availible to all authorized tuners directly from SCT.

Everything you mentioned is a factor of the person doing your programming
Dunno where you got your tuner, but they should be able to fix it since it is a CUSTOM tuner
You can make the TC lock up on mph, gear, throttle position, lot's of things...
I leave mine in the "highest effeciency" tune (i.e. race) all the time...
if I drive sedately, it shifts sedatly - if I don't, it shifts perfectly "crisp"...

Hard shifts when the truck is cold are easily defined:
Within the stock program, Ford uses what is called "torque reduction" to reduce torque at the shift.
For some reason or another, torque reduction is COMPLETELY OFF until the engine oil temp (or coolant temp, I forget which) reaches a certain point.
This can easily be turned back on to allow whatever shift settings are in the program to prevail, even when the truck is cold.
I did some substantial testing on this matter and the results were very consistent. As a matter of fact, in a certain revision of the 1704 (That's the Superchips Inc 1704, not affiliated with SCT), I allowed torque reduction (only at the shift) when the truck was cold so I could keep light throttle, low speed shifting consistent when the truck is cold or warm.
I found it a little bizarre that ford calibrated it this way, because after literally a few minutes of driving it would return to normal.

Yeah, it shifts normal once the temp gauge moves off dead cold. I just thought it was weird. Thanks for the backup info Vic, your answer makes sense to me.
I did install my SCT on the street mode this past Friday, only ran it for a few miles, about 7-10. Went out to the truck Sat am and had a check eng light on, code P1102. Went back to the stock tune and have gone about 100 miles since then, no P1102. Need to search on here and see what that is. BTW, I did not step on it wit the street tune, was being careful so I could see how the truck acted.

Hrmm, no reference to p1102 at all on FTE. A quick search on the net gave me a few links. One was for a Hyundai... not really what I drive 
, another was talking about a rough low idle due to defective MAF sensor, the rest were in other languages, heh.
Like I said, it has not come back. But for now I am going to leave the tune off there until I figure out the p1102. Time to read the SCT forums I guess.

I just programmed my '06 with a Flash pak from Superchips and I noticed right off the bat that there is a hesitation of about 2-3 seconds when I drop the shifter into either drive or reverse. It takes that long to get the bump when it engages. Can someone give me an idea of what is wrong?

I just uploaded the "Tranny only" program from my Edge Evolution last night and the first time I went to start it, I got the CEL and ran the code and also got the P1102 code. I looked it up and couldn't find it, but in reference to previous posts, I found that P0102 is the code for the defective MAF sensor. So in my confusion, I uninstalled the unit as I'm about to move this weekend and I don't need any problems.
Does anybody know what P1102 means?

Mass Air Flow sensor in range But Lower than expected. It is not liking the pressures it is seeing. Do you have an A/M air intake or any other mods. Also look for a restriction in the air inlet from the radiator core support up to the turbo.
Hope this helps
