Justin: The preloaded SCT X4 is gonna be for the '11 to '14 5-liter truck owners out there
who prefers the grab and go simplicity of a can tune as opposed to the more tailored
custom tune which can involve a little bit more work and will typically be a little bit
more expensive.
Now, the X4 will also be for the owners looking to go with one of the most trusted names in
aftermarket tuning to increase all-around performance of your V8 powered F150 while
at the same time giving prospective buyers some pretty cool features to tinker around
with.
Pricing is gonna land right around that $500 price point and the install will get a simple
one out of three wrenches on the difficulty meter from me when it does come time to talk
about loading up these tunes.
Now, in my opinion, the X4 from SCT is currently the most popular device in the tuning aftermarket
and for good reason.
It's gonna be one of the most user-friendly options, in my opinion, in addition to one
that will balance features with affordability.
Now, there certainly are gonna be some more expensive options out there, in fact, the
Livewire TS also from SCT comes to mind and that thing is gonna offer just about everything
you could want in a tuner along with a large attractive touchscreen display.
And on the other side of the spectrum, you're gonna find more affordable options like the
barebones Flashcal from Superchips which is basically gonna be for the F150 owners out
there who don't need a fancy device but rather are just here for the tunes and nothing else.
And with all that said, the X4 is gonna land right in the middle of those devices we just
talked about in regards to functionality, features but also price.
Again, 400 bucks here for the loaded X4.
Now, the X4 is gonna pack enough features to keep most gadget-happy owner satisfied
but at the same time, it's gonna be attractive enough and mountable for the truck owners
who wanna keep this thing on display at all times.
But now that you know who this might appeal to, let's get into some fun stuff here and
talk dyno numbers.
Baseline run using our 5-liter F150 gave us 267 horsepower and 301 pound-feet of torque
to the rear wheels.
With that tune uploaded, the truck is now making 289 horsepower and 306 pound-feet of
torque again to the rear tires.
This is good for a peak gain of 22 horsepower over those baseline numbers and gains of as
much as 21 horsepower and 21 pound-feet of torque underneath the curve.
But with our dyno results out of the way, let's talk a little bit more about the SCT
X4 device.
And on the surface, you're looking at a tuner roughly the same size as most smartphones
out there with a nearly three-inch full colored LCD screen.
And like most smartphones out there, the X4 can be viewed in your portrait mode which
will be straight up and down or flip it on its side and you'll have the landscape mode
which is just gonna give you a slightly larger readout.
And speaking of mounting the device, this seems like a great time to mention the optional
windshield mount that we do offer here on the site.
It's gonna make mounting the X4 a lot easier for those truck owners who wanna leave the
device on display at all times or if you wanna save yourself a few bucks, I've personally
used a cell phone holder in the past to hold my X4 in my truck but at the end of the day,
that's totally your call.
But diving even deeper into the X4, you'll see what this thing really is truly capable
of.
Now, in my opinion, here guys, the biggest feature is gonna be the on-screen gauges and
data logging and the real-time monitoring capabilities.
Now, this feature does allow to keep an eye on your truck's vitals at all times and check
on things like your air-fuel ratio, if applicable, intake air temperature, coolant temp, trans
temp, ignition timing, things like that and so much more.
Now, you can also use the X4 here to read and clear any possible diagnostic trouble
codes or check engine lights.
In addition to making changes to your idle RPM, your rev and speed limiters, your axle
ratio, in addition to your tire size.
Very important if you guys end uplifting your truck a little bit, throw on a set of 33s
or even 35s.
And if for whatever reason you did wanna return your truck to stock, you could easily do so
at the push of a button here with the X4.
The X4 does also feature built-in Wi-Fi and that's gonna allow you to handle any future
firmware updates wirelessly.
It is a nice little feature.
And speaking of wires, guys, one thing I really enjoy about the X4, might not seem like a
big deal to you all but that OBD2 cable is completely removable and that's just gonna
make storage in the glove box or the center console much easier.
Again, I know not the biggest deal in the world, but as someone who has owned both styles,
the X4 and the previous generation X3, it does make things a little less bulky.
Now, one thing to consider when checking out the X4 from SCT is that if you ever do wanna
go down the custom tuning road, maybe you wanna step up into some bigger modifications,
most custom tuners that I am aware of will be able to use the X4 to get those tunes over
to your truck.
Meaning, you're just simply not gonna have to go out there and buy a different device
to handle the custom tuning duties.
The X4 here can definitely do it all.
All right, guys.
I know we already uploaded the tune for the dyno earlier in the video, but I do wanna
walk you through the process just to show you how easy it will be.
One out of three wrenches on the difficulty meter here gang, maybe a few minutes of your
time from start to finish, and the best part is you don't even have to get your hands dirty
or open up the toolbox for this install.
Man: All right.
Now, we're gonna tune our truck and the first step is to plug our tuner in right to our
OBD2 underneath our steering column.
All right.
So, now we're gonna go ahead and tune our vehicle.
So, with our programmer plugged into our OBD2, all we have to do is turn on our ignition
and hit program vehicle.
Now, the first message is gonna say that this device is not legal for sale or use in California.
We don't have to worry about that here in PA.
All right.
Wanna make sure your key is on.
Now, this is going to process the data so that the engine preloaded tunes are for a
5-liter F150 and we're gonna go with the 93 octane tune here.
We're just gonna let it do its thing here.
Previous tune options changes found, load changes.
So, we can change your axle ratio if we change anything in our front and rear differential.
We didn't do that here, we did however put on some 35s.
That's already marked, so let's approve all that.
And this is for our tire pressure monitoring system, we're just going to deny that stuff.
Go ahead and start tuning.
So, this just says, "Make sure your key is on."
It's going to unlock our processor and start tuning our computer here in a second.
First, it wants to save our stock tune, that's going to be the way the vehicle came from
the factory.
So, we can easily just flash our computer back to stock.
So, let's let this run its course and I'll get back to you when this is done.
All right.
So, here we are, we're getting close to the end of saving our stock tune.
See the ignition pop on here preparing the data for our new tune.
Now, we're gonna upload our new custom tune.
So, let's let this run its course and I'll come back to you when this is over.
So, as you see here, we're coming up on 95%, we're almost done tuning our vehicle.
So, this right here is just clearing any codes that may have occurred.
There we go.
Download has been complete.
All right.
So, I wanna go through some of the menu options in your programmer.
As you can see, the first one is going to be program vehicle.
If you click into that you'll see one of the first things you can do is return to stock.
We're not gonna do that right now so I'm gonna exit outta that.
And then the next one is gauges and data log.
So, once you click into this, it'll say make sure your key is on.
Ours is on.
And then in here you're gonna see a couple gauge menus like the ETC throttle angle, throttle
position.
And if you give it a little gas, you can see some of the voltage and stuff in there.
So, let's go one back here.
We'll stop data log.
Now, vehicle functions down here.
You can read and clear trouble codes.
So, if your check engine light comes on, you can actually plug this programmer back into
your OBD2, read those codes, and clear them.
In the special functions, you can do a cam relearn as well as a crank relearn there.
So, we don't need to do any of that right now.
Vehicle info, that's gonna show you your VIN number and a couple other things like that.
As you see there, your ECU part number, TPS, what they're set at.
All that good stuff.
Device info, That'll just show you what kind of device, all your info.
If you need to send this out to SCT for any reason, they may ask you to go into that menu.
And that's about it.
This device settings, you can change your brightness, your color scheme.
There's a couple different options here.
You can go blue or you can go dark which is kind of like an inverted color option there.
We like to keep it on red.
And yeah.
That's about it for the menu here.
It's a very simple device, easy to use, and affordable.
So, that's gonna wrap up my install of the SCT Power Flash Tuner for this F150.
And for all things F150, keep it here at americantrucks.com.
