The SF XCal 2 has a built in tune like Diablosport and you can adjust it. You don't require your EEC code as the SF XCal 2 will read it and adjust to it.
The XCal 2 has to have a tune added to it by a dealer and then sold to you. How the dealer comes by that tune is different between dealers. You can than adjust it. You will need to provide your EEC code.

The XCAL II holds up to 3 custom tunes that are loaded into the programmer by whoever you're cold air intake dealer happens to be, for example if you purchase you're CAI combo from let's say.. tunable induction, SCT will load 3 custom tunes made for that cold air intake, and each of those 3 tunes, you are able to select either 87,89, or 93 grade fuels...once you decide on which tune you're going to install, the programmer automatically uploads you're factory stock tune into its memory, taking the place of the custom tune that you just downloaded into you're vehicle's computer, in other words.. the XCAL II is capable of holding just 3 custom tunes, so to make a long story short, each custom tune includes, each of the 3 fuel grades, they are not separate..As for the SF version..it has all the features of the Xcal II, but the SF comes preloaded with up to 4 SCT tunes by itself, instead of being limited to just a dealers custom tune, for that specific cold air kit. in other words, if you don't want or have the need for a combo CAI and just want to install a performance tune, without having to buy a cold air kit.. you have the flexibility and freedom to do so, with the SF version..it kind of operates simular to that, of the Diablosport Predator, only better...Anyway I hope this provides you with a more clear understanding, however you may want to give SCT's tech support line a call, and I'm sure they can provide you with a more in depth explanation, to all you're questions.mhanksii said:If the Xcal2 only holds 3 tunes, how does it save your factory tune and come with a tune for 87,89,93 grade fuels?

Also with the SF, if you should decide to install a cold air system, at a later time..The SF allows you to download up to 3 custom files, in addition to the already built in SCT tune, for that system via e-mail, right into you're SF programmer..However if you have just the Xcal II.. Just like TGJ had mentioned, then only a dealer is able to add tunes, to that unit..Mhanksii correction..the SF version comes preloaded with 4 built in tunes, in addition to saving you're stock tune in memory, which also has built in files, for all major cold air intake systems, in which you can choose from. However should you decide at a later time, to upgrade up to a blower, cams or anything that requires a custom tune, you will end up losing all of you're built in tunes, meaning, that you cannot download custom files into the SF, unless you wish to convert the SF into a regular X-CAL II custom tuner..In other words, if you plan on doing any major or serious mods..then go with the standard X-cal II, if on the other hand, if you're only going to be doing simple bolt on mods, such as UD pulleys, axle back exhaust, shorty headers and cold air kits, then the SF would be the way to go.. Anyway, sorry for the mis-information, from before... and BTW: I checked back with SCT tech. support today, to make sure that I got it right, this time..mhanksii said:If the Xcal2 only holds 3 tunes, how does it save your factory tune and come with a tune for 87,89,93 grade fuels?

I need to check this out about SCT X-calibrator. I was at a speed shop today and we were talking CAI's & SCT. He was suggesting that he just load/flash the computer using his equip rather that selling me the SCT with a CAI. He said if the dealer was doing a warranty reflash on my car, then the SCT would not work on it any more as the dealer's re-flash would change the code in the car's computer - making the SCT useless to me.
He also said the dealer could tell if an SCT had been used on the car whereas his equipment would not leave that trace.
Having him flash the program using his equipment would cost me $75 less than his selling me an SCT w/tune.
What do you think? Is this correct or BS?
Thanks

HHHMMMMMM
The only one I know for sure is if your car gets reflashed by ford then you can get that computer code and have your hand SCT reflashed to match. Also I believe that the new SCT SF fixes that by not needed the computer code to start with.
That wold also be a good trick if you could completely reflash a computer and it not be detectable
! It doesn't void your warranty anyway. My dealership is also a Steeda dealer and if you buy Steeda parts they flash it with a canned Steeda tune for you!

When you mention, they flash it with a canned Steeda tune, are you referring to what they call their pro calibration tool ? because if you are..that device doesn't re-flash, in the same way, as an XCAL II.. All their pro cal tool does, is re-flash the PCM's air/fuel timing curve (only) which is why they require it for use, with premium fuel only..other than their CAI kit and rear end gears, it really does nothing, other than just that.. In fact, you can't even make any adjustments or any changes, at all...So if you're going to select a Steeda CAI..make certain you either go with the SCT XCAL II or SCT XCAL II SF. 9415-A or Diablosport Preadator.mhanksii said:The only one I know for sure is if your car gets reflashed by ford then you can get that computer code and have your hand SCT reflashed to match.

SCT and myself unclear!
no I was talking about flashing it with a canned tune out of a Xcal but thank you for clearing that up for us. I reread my post and I didn't make that very clear at all. I stand corrected and red05bullitgt, love reading your post very clear and technical. Thanks for all the info you have passed on to me and the other stangnet readers!

Well, thats what were all here for, and what these forums are all about, and I appreciate you're compliments, Mhanksii..As for my posts being clear and technical, I do lots of research and background checking into each topic, before posting them, and if I'm not 100% confident or have any doubts, I'll find someone who does have the answers, and will always ask questions, until I'm absolutely certain, that any information I provide, is accuarate.. So once again..thanks.mhanksii said:

Why do you regret the buy? Just for one extra tune? Unless I amreading this thread wrong that is the major diff between the two. I'm planning on a supercharger later, I need the xcal 2. right? I am looking at the xcal2/AIC combo as well. Was it here you got it? http://www.tunableinduction.com/
Part Shopper
I got mine through part shopper to help support the forum, but it was dropped shipped from tunable inductions.com. I can't say enough about either of them. Both the part shopper fast/friendly service and Mr. DeMolet workmanship. Man talk about wake up a few extra ponies! This should be a must on all GT's. In fact ford should make you pick it out and pay for it when you order the car! (just my $.02)
The SF also does quoted from TGJ "The SF XCal 2 has a built in tune like Diablosport and you can adjust it. You don't require your EEC code as the SF XCal 2 will read it and adjust to it."
Other than that, they are the same unit. I don't regret it for one second though!!:SNSign: :Track:

I would recommend the Pro Racers Package over either of the two other options. You can do so much more. I did not like the high idle at start up cold and warm engine. Fixed that! And to have the tranny shift into OD at 24 mph is ridiculous and has to decrease the longevity of the transmission. I upped my converter lock up speed to make it's bands last longer. Most of the tunes come with a high idle, 850, even after start up. Changed back to 650. I was able to tailor the engine/tranny to much better suit my needs and likes.
