      Joe: Hey, guys. It's Joe from AmericanMuscle and today we're gonna be taking a closer look at the Bama X4/SF4 Power Flash Tuner with two Custom Tunes, fitting all '15, '16, and '17 3.7 liter V6s. Now this is gonna be a great option for you if you're looking to improve the power and drivability of your Cyclone with some great tunes as well as some great tools all at a budget-friendly price tag.Now, before we dive into what the X4 itself can do, let's talk about dyno numbers, '15 Mustang V6 with the automatic trans 93 in the tank for both before and after run. And for our baseline, we put down 241 horsepower and 235 foot-pounds of torque at the rear wheels. Then we applied our 93 octane Bama tune, and we got 258 horsepower as well as 248 foot-pounds of torque. And that is good for peak gains of 17 horsepower and under the curve 17 horsepower and 20 foot-pounds of torque. Pretty respectable numbers out of our Cyclone there, 17/20 [SP] under the curve. That's gonna be in that lower RPM range as well. So, that's something you're gonna notice as soon as you step on the gas, 3,000 to 4,000 RPM. That's definitely gonna register on the good old butt dyno there. That's going to improve drivability and on top of that, you're gonna get a little bit more throttle response. And automatic cars, they're gonna benefit from snappier shifts as well.So, knowing what gains you can expect from something like this, let's talk about how this is gonna work and other features of the X4. Well, if you do decide to go with this one, what's gonna happen when you purchase this is Bama is going to send you an email with a sheet to fill out describing your car. First thing they're gonna ask you is some facts about your Mustang. Is it an automatic? Is it a manual and what's the computer code? After that, they're gonna ask you if you have any mods done. And that can range from cold air intakes, mass airflow sensors, cams, injectors, fuel pumps, exhaust, rear gear ratios, bigger rear tire, stuff like that, you guys get the idea. After that, they're gonna ask you what octane levels you want for your two tunes. Obviously, we did our run on 93. So, if you want the most gains and you can get 93 gas in your area, go with that, 91, that's gonna be a nice middle ground if that's all you can get in terms of gas. And then, 89 and 87, they're gonna be more toward the efficiency side. I recommend going 93 for one, 87 for the other. That kind of gives you the best of both worlds.Now that Bama has all your info, they're gonna take about two to three days to actually write your custom tune, then they're gonna email them out to you at which point, you plug the device in your PC, drag and drop some files over, then you can bring this over to your Mustang and start the tuning process, which we're gonna show you how that works in just a second here. But it is a really simple process. Now, one thing I did wanna note is when you apply a tune using the X4, that is going to pull off your stock tune first. So, if you do ever need to revert to that stock tune, it's gonna be saved on the X4 for you to do so.Now, one thing I do wanna touch on that makes the X4 a little bit different from other tuner brands out there is once you purchase a Bama tuner, you're enrolled in Bama's Free Tunes For Life. Now, what that means is if down the line, you pick up a new mod that requires a new tune, all you have to do is submit another form over to Bama with that new modification in there. They're gonna cook you one up and email you one back to accommodate for that mod in about two to three days and then you're off to the races. If you're looking to grow your build and a tune that can keep up with you without having to drop hundreds, maybe even thousands of dollars on dyno tunes, this is gonna be a great option.Some other great features of the X4, this guy is Wi-Fi capable. And that means, updates, they're gonna come right to the device quickly and painlessly without the need to plug it into a computer. It's also data log capable. So, if you need those fine revisions, you could offload files to your PC using this cable right in the middle here. It also features a three-inch LCD display, which can be displayed in portrait or landscape mode and that is great because this can display up to eight real-time vital readouts for your Mustang. And that includes, but is not limited to air-fuel ratio, intake and coolant temp, boost if you're going forced induction and ignition timing. Last but certainly not least, this also works as a diagnostic tool, allowing you to check and clear those check engine lights if you need to.Pricing for this kit is gonna be really budget-friendly, dropping in right about $400. And that's gonna be a great return on investment. Not only are you unlocking some of that power that Ford left on the table, but the X4 does come with some awesome tools that any Mustang owner out there should be able to put to use. The install for this is gonna be really, really easy. We're looking at a one out of three wrenches here. No need to pop the hood or even get your hands dirty, plugs right into the OBD2 port. You'll be up and running in about 15 minutes. We're gonna show you a clip on how to upload a tune to one of our S550s. One thing to keep in mind, it's gonna be the same process no matter what S550 you have, as they're all the same generation. So, without any further ado, let's head over to the Mustang. We'll show you how to upload a tune and what this thing can do.Man: Guys, first step here, grab the harness included in the kit. You're gonna plug in this side to the OBD2 port located on the left side under your driver side dashboard. Once that's plugged in, take the other side, pop it into the slot on the top of your X4. And we're good to get started.All right, from the main menu, I'm gonna take you guys through the process of tuning your vehicle. So, select program vehicle from that main menu, hit continue on the street notice, put your key in the on position, but don't start your engine, and press Continue. Now it'll give you a bunch of different options to actually modify any tune you select. We're gonna go with 93 race, but select the one that you wanna flash now. At this point, it'll move forward asking you if you wanna make any additional changes. There's a bunch of menus relating to that. So, make the changes you want. We're gonna keep our file pretty much the same that it comes with from Bama. All right, so you wanna change anything you see on this menu and hit Approve. Continue to special options, including tire size, things like that. So, did you change your tire size? We did not. Don't wanna change gear ratio and no on the TPMS settings. Confirm that it will disable your pre-loaded tune to move forward. All right. Key in the on position if you haven't done so already, and it will save your stock tune to the device and then begin to flash. It will load 0 to 100 a couple of times. Just let it do its thing. Don't unplug it and don't turn the vehicle off unless it directs you to. All right, at this point, it lets us know the download is complete, you can select Done and you're good to go.Before we disconnect, I wanna take you through some of the other features of the X4. So, if you go under program vehicle, gauges and data log is your next selection. You wanna make sure the key is on before you move any forward. What this will do is allow you to monitor live engine vitals on the fly at any time as long as your device is plugged in. Now, it's more of a gauge pod, but there's multiple pods, multiple gauges. As you can see on the screen, we have two. They're both the same at the moment, but they are customizable. Now, if you go to the right, you can data log, can record a data log, select the data log file, select the gauge layout. I'm gonna change that gauge layout to something we can monitor three pieces of information with. Now, we have boost in PSI, control module voltage, and coolant temp but you can change those, like I said. So, in EcoBoost, you might wanna monitor boost. Control module voltage, coolant temp, those are all customizable. If I wanna change coolant temp to intake air temp, we can hit Approve on that and it changes that gauge. You can monitor up to eight at a time. If you wanna select the gauge layout that monitors eight, this is the max. Now, it's really useful for guys who wanna take care of that information on the fly. And again, you can record data logs, send that to your tuner, make revisions, so on and so forth. Now if you hit stop data log, it takes you back to the main menu.Under that, Vehicle Functions, read DTC codes, clear DTC codes, and Special Functions. Now, DTC being diagnostic trouble codes. So, if your check engine light comes on, plug this device in, read the code, get the description, and then you can clear it once it's taken care of. No need to pick up any additional device. Special Functions, most people won't touch. Cam relearn, cam reset, those we'll leave be for now. Most people aren't gonna have to worry about that. Vehicle Info. This is useful if you're requesting a new tune, if you need access to your VIN number, your ECU strategy code, that's gonna be on hand. Device Info, similar but for your X4 you'll have the part number, serial number, the firmware, and software version, and how many unlocks you have, if your status is married, so on and so forth.And then finally, Device Settings. You can check for updates, both plugged in or via Wi-Fi, which I think is very useful. Wi-Fi, if you're in range of the Wi-Fi network, you can connect that to do everything wirelessly. The only big difference here between this and the newer Rev-X is there are no cloud capabilities. So, everything's done on the computer as far as downloading tunes. But if you're not to worry about that wireless aspect of it, the X4 is still a really good device. The rest of the settings are pretty much simple for any handheld, brightness, orientation. You can change the landscape, you can change the theme from red to blue, can change it to dark. There's a number of settings there. There's also audio. So, every time you click a button, there's a little beep. You can turn that off here. And that way you don't have to worry about that sound. Finally, Startup function I think is very useful for guys who are always going to want to monitor those gauges that we looked at, the gauges and data log screen. You can select your startup to go immediately to the gauges screen. So, if you have this constantly plugged into your OBD2 and you have it mounted on the windshield, this might be a good thing to take advantage of. Finally, factory reset. We hit Exit, back to the main menu and that's your X4.Joe: Guys, so that's gonna do it for my overview of the X4, fitting all '11 to '14 Cyclone V6 Mustangs. For this product and other great ones, make sure you keep it right here at AmericanMuscle.
