Couple questions on these tuners. One is as I have read but not got conformation on is that these tuners can only be used on one car? The reason I ask is I may have access to one somone else had bought but if it is locked to the vehicles VIN that wont do me much good. Second is the difference between the X3 and the SF3.

As I understand one only has preset tunes that cant be modified and the other is able to have custom tunes. Can anyone else elaborate on this for me? Im kind of confused on why you would buy one that only has preset tunes that you cant change. And lastly who should I buy from?

I am also interested in a CAI and a few sites I have seen have combo kits where you get both the intake and the tuner. Is this a better route to go than buying them seperately and also which combo should I buy and where should I buy from? The dealer does not need to install a tuner. All you do is plug it into the ODBII under the dash and follow the on screen directions.

A caveman could do it, maybe even a Gecko. A dealer has to prove your mod caused the problem to void your warranty. Regardless, only the part replaced or the parts that are effected by the part replaced would be ineligible for warranty if it was found that it caused the problem. In other words, if you have a problem with your A/C and they see you have a tuner and intake they aren't going to deny the warranty claim. The come with 3 pre-loaded tunes ready to go out of the box. You have additional empty slots on these tuners for custom tunes. Custom tuning generally is not required but can be usefully if there are very high performance mods such as Nitrous, Forced Induction and so on.

If you Mustang has simple upgrades like cold air intake, exhaust, throttle body and so on the pre-loaded tunes will be your best RWHP pick-up. If they need to tune further in the future anyone with the Advantage III SCT Tuning software that many of us dealers have can create another tune for your car as it progresses to a more highly modified state. Generally speaking as well these are your best buy and works with most any Ford application. Sincerely, Mike.

Just received an email from Steeda notifying me of a 'Urgent Notice: SCT X3 Tuner Critical Update' to which I followed directions and updated my device. That means returning vehicle to stock, updating and then reloading tunes. Well, went to reload tunes and now I cannot! Contacted Steeda and was told to contact SCT.

Been on hold now for 10+ minutes and will likely have to leave an email message since they close in 20 minutes. Problem is the car has the Steeda CAI so it's not suppose to be run with the stock tune so I'm dead in the water until this gets remedied. Just an fyi for anyone else that might have gotten the notice. 1 I updated mine and when it installed the new software a dialogue box came up and said Unplug/Plug did that and lost everything in my tuner blank screen. My computer says unknown device now. I called Steeda and was told to call SCT, I did that and held on for 30 minutes with no response, then tried there chat line and it timed me out 4 times no luck, then sent an email and no response yet. So what are we to do?

I also have the STEEDA CAI which says don't drive it with a stock tune which is I have now. So my car is setting in the garage sorta like a lump on a log. Since Steeda sent out the email they need to take a lead to resolve this. Right now I am dead in the water.

Seems like we both learned the hard way now we have to get some kind of resolution. The DAY OF update pwn3tage. I'm betting they're probably FLOODED with phone calls.

All you can do now is wait for them to fix their screw-up. In the mean-time, I suppose you could log in to facebook and rant and rave. Should be a good following of that building up by now. I like the title of this thread. No matter WHAT you're updating software on, you never want to be one of the first. Someone has to do it though. Other will read this thread and say, 'Whew.

Dodged that bullet'! Making this a sticky till it gets resolved. Thanks for the comfort Noobz!

That's why I posted quickly so others may not do so. If I am the test rat, it doesn't hurt so bad if others are spared the pain. Harold, I was quick to think that Steeda should take the reins on this too, but if SCT screwed up then it isn't Steeda's fault. Anyway, yeah it sucks, crap happens, they know there's a problem (I hope!!!) and we have to have confidence they'll resolve it. It's really gonna be a pita if we have to get the tunes from Steeda again.

My tuner came preloaded and I can't find the tunes on the tuner. Was told it would take about 24hrs to write them (but don't they have them on file already if they wrote 'em?) and then send them out. Rain like a sum-beech for the next 48hrs!!!! I did go to Facebook,SCT Performance and vented my problem. This was last night and this morning I had two answers from them apologizing for the support but they had been swamped since this update came out. Very poor planning on there part you would have thought with there experience they would have known they were going to have issues. But enough of that we did communicate on Facebook and a tech called around 11:30 AM EDST over 24 hours later and after a total of ten minutes had my problem solved and I was able to reload my tune on the car didn't loose any of the programs.

The tech Brett was very cordial and knew what he was doing and thanks to him for fixing my problem. I was really scared I was gonna be out of a car for days, real problem. They now say if you aren't loading any programs right now to wait and do the update due to the workload and they have extended there hours to accomodate they problems. I still think Steeda should have taken more of a lead in resolving this since the tune was theirs. But with today's times you pass the buck when you can. Guess I'll have to take the facebook path. I sent SCT an email message yesterday via their homepage link.

Sct X3 Latest Firmware

Also called back this morning and listened to their beautiful music for too long. Haven't heard a word from SCT yet. I did contact Steeda again and since it sounded to them that my tunes were wiped, they are re-sending me the tunes. I have the auto update which is what I did with the tuner. IF my tunes are wiped clean like suspected, which they shouldn't have been according to Steeda (makes sense to me!), I should be able to reload them onto the tuner and then onto the car.

Sct Firmware Update

Not sure if that helps with steps. Will post back when I get somewhere.

Sct X3 Firmware For Macbook Pro

Good idea to sticky this while the problem exists. Well, got thru to SCT finally last night. They remotely wired into my computer too and my tunes were wiped clean. It was nice of SCT to let me know I'll have to re-acquire the tunes and reload them.

Would have been a hellofalot nicer to received a message stating the update would/could wipe the tunes, then I could have backed them up and I think SCT would have had far fewer calls. Thankfully, Steeda rocks and had already started working on getting me the tunes. Hopefully I'll have them today and only be without the car for two days.
