Review & Install Video
Hey, guys. Adam here with americanmuscle.com. And today, we're taking a closer look at, installing and of course dyno testing the Bama X4 SF4 Power Flash Tuner from SCT, available with two custom tunes fitting all '15 to '17 Mustang GTs. Now before we break down all the details of the X4 itself and the tunes, what do you say we head over to the dyno, take a look at our dyno graph?Now, guys, we strapped our '15 GT down to the dyno, 93 octane in the tank, completely bone stock otherwise, ran a baseline run, we walked away with 382 horsepower, 359 pound-feet of torque at the rear wheels. We then, of course, uploaded the 93 race tune from Bama, walked away with 403 horsepower and 383 pound-feet of torque at the rear wheels, that's good for peak gains, 21 horsepower and 24 pound-feet of torque at the rear wheels. Those numbers right there are pretty good right off the bat but curve gains are even more impressive. Under the curve, we're seeing gains as much as 32 horsepower and 39 pound-feet of torque at the rear wheels. The biggest torque curve is going to be right at the low end there which is really gonna make such a huge difference on the road higher end of the RPM band, we're seeing really good horsepower gains, but all across the RPM band, really impressive numbers altogether.Now what do you say we break down the features of the X4 here? Now the X4 from Bama comes with those two tunes, 87 octane and the 93 race from Bama, 87 is gonna be a good choice for guys to upload on their daily driver or their weekend warrior, just looking for something a little extra for their daily commute just to make things a little bit more interesting without having to grab 93 pump gas. But if you're really looking to maximize performance as you just saw on the dyno, the 93 tune is gonna be the way to go. The 93 tune is taking a number of other parameters into consideration including air-fuel ratio, timing, spark, and a number of other parameters to really maximize your vehicle's performance and any other mods on it. This is great for stock, modified or even heavily modified Mustangs.Now in addition to those tunes themselves, there's a number of other features to look at. The X4 device does come with a DTC code reader feature built-in, so the diagnostic trouble code being your check engine light, you no longer need a separate dongle or no need to go to AutoZone to get them to read the code. Plug this guy into your OBD2, read the code, get a brief description and you can clear it right on the X4. There's also the gauges and data log screen as well, you can monitor live engine vitals all on the screen at once and you can change them up, things like air-fuel ratio, coolant temp, air intake temp, sensors. You can monitor so many options and cater it to your preference. 'd recommend picking up the windshield mount from SCT sold separately just to mount it up on the windshield and keep it within arm's reach and within eyesight of the driver seat at all times, but of course not necessary. Now data logging is another thing to keep in mind as well, anytime you think you might want a revision from Bama, you can run a data log, record it, send it over to Bama via email and they can take a look and tell you what needs to be changed, if anything, so that's a good feature to have right there as well. Keeps an open line of communication to your tuner.Now with that in mind, anytime pick up a Bama tune and a corresponding device like the X4 or the Rev-X for example, you're automatically enrolled in the Bama Free Tunes For Life Program. What that essentially means is for the lifetime you have that tuner and your vehicle paired, you get free revisions from Bama at any time. That means if you add some of those bolt-on power adders which let's be honest, we all do all the time forever, it's just how it works, things like cold air intake, long tube headers, cat-back exhaust, hit up Bama, they'll revise your tune to include your new power adder or even if you remove anything, they can make your tune, maximize your vehicle's performance given what you put on. So that's a huge value included in this package.The whole thing comes in right around 400 bucks. Install is gonna get one out of three wrenches on our difficultly meter. Anybody can tackle this in the driveway at home with about 20 to 30 minutes from start to finish. I'm gonna show you every single step of the process. Keep in mind I'm gonna walk you through that process inside of our '18 EcoBoost, but know the process for uploading the tune and all of the features on your X4 are the exact same for your '15 to '17 GT, we're just using our '18 as that guinea pig in the car. So what do you say we head over there and show you that clip?Guys, first step here, grab the harness include 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 is 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 vehicle from that main menu, hit CONTINUE on the STREET NOTICE, put your key in the on position, 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 want to flash now. At this point, it will move forward asking you if you want to 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 want to 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 want to change gear ratio and no on the TPMS settings. Confirm that it'll disable your pre-loaded tune to move forward.All right. Key in the on position, if you haven't done so already and it'll save your stock tune to the device and then begin to flash, it'll 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, can select DONE and you're good to go.Before we disconnect, I want to take you through some of the other features of the X4. So if you go under PROGRAM VEHICLE, GAUGES/DATALOG is your next selection. You want to make sure the key is on before you move any forward. What this'll 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 DATALOG, can record a datalog, SELECT DATALOG FILE, SELECT 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. You can change those, like I said. So in the EcoBoost, you might want a monitor boost, CONTROL MODULE VOLTAGE, COOLANT TEMP, those are all customizable. If I want to 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 want to select the gauge layout that monitors eight this is the max. Now it's really useful for guys who want to take care of that information on the fly and again you can record datalogs, send that to your tuner, make revisions, so on and so forth. Now if you hit STOP DATALOG, 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 code. 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, 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 is done on the computer as far as downloading tunes. But if you're not too worried 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 to landscape, you can change the THEME from RED to BLUE, you 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 datalog 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. Well, guys, that's gonna wrap up my review, install and dyno test of the Bama X4 SF4 Power Flash Tuner from SCT, with two custom tunes for the '15 to '17 GT.
