      Video Review & Installation

      What's going on guys and gals, Travis from, and today, I'm gonna show you how to quickly and affordably squeeze some extra horsepower and torque out from underneath the hood of your 2014 to 2018 5.3-liter powered Silverado or Sierra. I'm talking about a fancy little preloaded tuner like this guy, this is SCT's new BDX tuner, comes in at around the $400 price point and it's currently the most affordable option that includes a pre-loaded tune that's actually customizable. I'll touch on that in a little bit. But even better, it can store up to 10 custom tunes. But I do have to say, guys, even the preloaded tune that you get on this device is incredibly effective. We actually went ahead and we ran our truck on the dyno stock to pull some baseline numbers. We ended up making 260 horsepower and 288 pound-feet of torque. Those numbers might seem a little bit low, that's because we have some aftermarket wheels and tires out back, but we went ahead, we threw the preloaded tune on this guy, all we had to do is update our fuel octane setting from 87 to 93, we left everything else the same, and we went ahead and we ran it again. And we ended up making 284 horsepower and 319 pound-feet of torque. That makes for some pretty respectable peak gains of 24 horsepower and 31 pound-feet of torque. But if you take a second, look at that graph, you'll notice we see very consistent and very large curve gains all the way from idle to pretty much redline. In fact, our curve gains top out at plus 30 horsepower and plus 45 pound-feet of torque. And again, it stays pretty consistent across the curve. Guys, chasing that kind of power without a tune, you'd really be turning some wrenches under the hood for quite a while, whereas you can do it with this guy in a couple minutes by pressing a couple of buttons.Getting your tune installed and really getting the device updated and working only takes about 15 minutes. If you're not familiar with this kind of stuff, guys, it's incredibly user-friendly, and I'm actually gonna walk you through the entire thing step-by-step. So, for that reason, I'm gonna go ahead and give the install, or rather I should say the use of this thing, a very simple one out of three wrenches on the old difficulty meter. If you're a first-timer, you're not very familiar with this kind of technology, not to worry it's very user-friendly. So again, if you're looking for one of the most affordable preloaded tunes that also allows you to store custom tunes and even tune your truck wirelessly, so to speak, then SCT's got you covered with their very cool BDX tuner. Go ahead and check it out more if you decide to stick with this option over any of the other ones. You can come back in just a second, I'm gonna show you guys how to get this thing updated and tune your truck, and then, I'm gonna walk you through the complete setup and all the other applications step-by-step.Okay, so really all you have to do is pull the tuner out of the box, grab the data cable, plug the HDMI end into the port on the tuner, and then, route the cable underneath the steering column and plug it into the OBD2 port. Once you've done that, go ahead and get situated, put your key in the ignition and turn it to the on position. First thing we're gonna do is going over how to actually tune our truck, and, in order to do that, you wanna select Program Vehicle, we're gonna be using the navigation buttons down here on the bottom, up and down, left and right, and our center button for enter or exit.And it's gonna give you this little prompt letting you know you do need the key in the on position, which we already do, so we're going to click Continue. Now, if this is the first time using the BDX, it will prompt you to connect to Wi-Fi. That way, it can provide updates to the device, including for the preloaded tune files. So go ahead and click Continue. It's gonna bring you to the Wi-Fi scanning screen here, while it scans for different connections, then we'll find the appropriate connection and we'll connect to it. It's the same thing as any smart device, whether it's Android or iOS, you just need to find the appropriate Wi-Fi connection, click enter, and then, you have to enter the appropriate passkey. Now, unfortunately, I can't show you guys this part, so let's go ahead and enter that, and then, we'll continue.Okay, quick jump cut there, guys. Sorry, I had to keep that secret, but now we're downloading all the necessary files that we need in order to update the BDX tuner itself, as well as our preloaded tune files. You can see, we have a ton of updates here, SCT's pretty on point with that stuff. So just go ahead and let this run for a minute. This does take a minute or two, so you wanna make sure your battery voltage is good as well, you don't want to lose your connection during the update process.Okay. All of our files have been updated, it should give you this little congratulations screen, go ahead and click OK to continue. And now, that we have some of our files downloaded, it's gonna process some of that information and apply some of those updates to the device itself. We'll just have to wait another moment while this completes.Okay. So our firmware updates have now been applied, let's go ahead and click Continue one more time. Now, cloud sync is only necessary if you're downloading specific preloaded tuning files or other files that you've already had created. We don't care about that right now so let's go ahead and click Skip. And this is just a legal disclaimer here. While we're on this screen, something to take note of, after you do tune your truck, if you ever want to untune it, put it back to stock, simply select the Upload Stock option here in the Program Vehicle page. But obviously, we're not doing that right now, we're gonna install our tune so we're gonna click Continue. Make sure our key's in the ignition and click Continue again.Okay, so now we have our home screen for our available tunes. You can see here we have our available custom tunes which is where, if you synced your device and had a custom tune available, it would install and display there. But obviously, we're working with our preloaded tunes today on our Silverado so we're gonna select the appropriate truck and go ahead and select it one more time for the appropriate transmission tune. And click Continue.Now, there's a bunch of options that you can actually update in the preloaded tune file as well, and we actually have to make a modification to one of these in order to actually get our performance upgrades here, if you will. We have to update our fuel octane from 87 to 93. You can go with 91, if you want to, if 93 is not available in your area. But basically what happens is, once you select the new octane rating, the device and the preloaded tune file will actually adjust air and fuel and timing automatically based on that input. While you're here, you can also make some different changes here. You can set what your idle is in drive and in park when you're actually driving around. You can actually make advances to timing yourself as well as to spark. You can also make changes to things like your axle ratio, if you've installed new gears. You can change your speed limiter. There's a bunch of different options in here that you can make changes to. Again, we're only interested in what the preloaded tune can do for us based on our fuel, so we're just gonna skip all that for now and hit Approve.It's gonna ask that you confirm all the changes that you've elected before we continue. You can see we have our 93 octane selected, everything else looks good. So click Continue again. Now, at this point, the BDX is gonna begin communicating with the truck. So what it's gonna do first is it's gonna save kind of a screenshot, if you will, of the current file that is installed, our kind of stock tune file, if you will. That's what's gonna be used if you ever revert your truck back to stock. So, once you begin this process and you actually begin communicating with the truck, it's very important that you don't unplug the device at any point. You also don't wanna turn off the key in the ignition, that'll terminate the connection and it will interrupt the tuning process.All right. Our stock tune file has now been saved. Now the device is gonna do a little bit more processing here as it builds the preloaded tune file. And it looks like it's gonna do a little bit more with saving our stock file.Okay. Now the BDX has finalized our tune with the changes we've made, obviously, being our octane rating. And now it's writing our tune for installation. Okay, our tune file has successfully installed, now it's gonna prompt you to cycle the ignition off. Go ahead and do so and click Continue. And once it's finished powering down the vehicle, it'll give you this little Programming Complete screen letting you know that your tune has been successfully installed. That's really all there is to tuning your truck. At this point, you can turn the motor over, go take it out for a drive. And then again, if you ever do wanna go back to a factory tune, simply come back in here, can skip all this stuff and go back to Return to Stock here, on the Program Vehicle Street Use notice page.If you guys wanna stick around here, I'm gonna show you all the other functions on the BDX. Next up are the real time gauges that we can monitor while we're driving around, as well as our ability to data log our truck. And, in order to configure our gauges and our data log application here we're gonna click Continue again with the key in the on position. And if this is our first time setting up for data logging, it's gonna ask that we select the appropriate vehicle. And obviously, we are working with our Silverado today, so let's go ahead and find the appropriate PCM configuration.Looks like we're gonna be working with the GM gasoline, so go ahead and highlight that configuration. Hit the right arrow to select Continue. All right. Now, this is the home screen for our real time gauges. We'll go over our gauges first before we go over data logging here. So if you want to make changes to the layout or the configuration of the gauge screen, it's pretty simple, all you need to do is select one of the up or down arrow keys and you can actually highlight the individual gauges that are being displayed. By default, it'll display our vehicle speed and our engine RPM, so let's make a change to vehicle speed by hitting the enter button, bring you to the individual gauge home screen here, you can see the item being displayed and the unit that it's being measured in. And this is gonna apply to all the available gauges. So if you wanna change what we're being displayed here, select Item and click Continue.You can see here it has our default gauge up here, vehicle speed. If we wanna select a different gauge, it's pretty simple, you just navigate through all the available options and select the appropriate gauge you wanna monitor. There are definitely a ton of options in here, too many for us to go over, but just as an example let's select our intake air temperature. Now, you can see Intake Air Temp is displayed next to Unit and we want to display this in Fahrenheit instead of Celsius. So that's how you change the unit of display. And again, click the right button here to approve, click the center button to okay it. And now, you have our Intake Air Temp, it's displaying a current value here in real time, of 111 degrees. And again, same process if you wanna change any of the other gauges themselves.Now, if you want to begin data logging or if you wanna actually change the layout of the gauge screen, pretty simple, you wanna press the right arrow and it's gonna bring you to all the different menus and functions for this screen. If you wanna start recording your data log, you can simply press the OK button there, and you can see we have this nice little recording icon in the middle. So once you have that recording icon in the middle and you actually turn your truck over and start driving around, the BDX is going to log and record all the information that the PCM is also monitoring. So it's gonna record all your values for intake air temp, it's gonna record all your values for engine RPM, it's gonna also record all the data being provided from all those other values in the backend here on our available gauges. Now, when you're done data logging, pretty simple, go ahead and click to stop data log. It's gonna bring you to the home screen but it's gonna automatically save that run file on the device. It's not gonna give any prompts or notifications letting you know but you can pull that data log file using SCT's software on your desktop using the provided USB cable. If you do find yourself running into problems with your data log files, you might wanna troubleshoot if you have the correct configuration, in which case, you would hit Select Datalog File, and then, you can select the appropriate configuration here.So let's go ahead and back out. And, in order to change the gauge layout screen, pretty simple, you wanna hit Select Gauge Layout. And you'll see all the available layouts that you can choose from here. I believe you can view up to eight different gauges at one time. And you can see here they are displayed in a landscape orientation, so you wanna find a way to mount your device to display that. But there are a bunch of different configurations. Also, keep note here when you go into a landscape mode, it's also gonna change the orientation of the buttons themselves. So let's go ahead and select a different gauge layout while we're back to vertical here. And you can see you can actually have eight gauges here in a vertical orientation, so that's pretty nice.The device will also display the last known values that you've recorded and it'll display minimum and maximum values in your data log file. So if you wanna reset that while you're viewing your device, simply hit Reset, it'll bring those values back to default. So let's go ahead and back out of here.So we have our new gauge layout here. You see we have our vertical orientation instead. Now, if you wanna exit out of the gauge cluster screen, you actually have to click on the right arrow to get to our menu. And if you hit Stop Datalog once again, it'll bring you back to the home screen. You don't actually have to have a data log file running to do that but that's how you get back to the home screen from the gauge cluster screen.Next option up is our vehicle functions. This is also pretty useful, this allows you to read and clear diagnostic trouble codes also known as check-engine lights. So let's say you're driving around, you get a check-engine light, you get a rough idle or something like that, you can actually come in here and select Read DTC Codes. Obviously, you have to make sure the key's in the on position, and click Continue. And if you do have a check-engine light or any other dash flights, the BDX will communicate with the PCM and it'll display an alphanumeric code that corresponds with the underlying issue. It'll usually be something like P001 or whatever. But, once you have that alphanumeric code, you can actually pop that in on the internet and you'll, most likely, be able to find what the underlying cause is so you can fix it. It's a nice way to save a little bit of cash, as opposed to go to the dealership or your local shop. And then, if you wanna clear that code, whether or not you fix the underlying issue, pretty simple, select Clear DTC's and click Continue. And it'll clear those codes from the dash. Just keep in mind, if you don't actually correct the underlying problem, that dash light might return.Now, we also have special functions here. You're not ever really gonna come in here for any particular reason but I wanna show you guys what's in here just so you're not curious. You have to go through all these different update options here, we can skip those for now. But it's gonna bring you to the vehicle functions home screen here. Crank relearn, that's not something you'll ever touch, that's something that a shop would likely use after performing some engine work. Not gonna get into the details on that. If you know what a crank relearn is, I don't need to explain it to you. If you're not sure what it is, not anything to bother with, it doesn't relate to performance, or tuning, or diagnostics, or anything like that.You also have your tire-pressure monitor system in here. And you can actually adjust this function from this screen, can actually adjust what the cut-offs are for tire PSI for your TPMS, to give you [inaudible 00:15:17]. So you can actually input a TPMS value between 1 and 120. And then, if your tire pressure ever falls below that value, you'll get a dash light letting you know. So we're just gonna put in 35. That was interesting. But, once you put that in the horn will honk, for some reason, letting you know that you've correctly input the TPMS threshold, and you'll get a successful change notification. And then, you can click Exit and it should bring you back to our home screen. It's gonna bring us back to the vehicle functions page instead, but you can go ahead and click Exit. And click Exit one more time, that's gonna bring us back to the home screen here.So those are the three primary applications on the BDX tuner, the ability to tune your truck, the ability to monitor and data log in real time, and the ability to read and clear diagnostic trouble codes, as well as the ability to set the threshold on your TPMS. You can also pull some basic vehicle information from the BDX, this is very useful, especially if you're doing custom tuning or diagnostics. You just have to make sure the key's in the on position once again. Click through those disclaimer screens, it'll show your VIN as well as your current operating system ECM firmware version. You'll also have some other pertinent information in here related to custom tuning, and you can find your strategy in here, can also find the serial number for the device at the bottom here. And that's gonna apply to device info as well. Can see, we have some of our basic tuning information, serial number for the device, firmware version, as well as our preloaded tuning, custom-tuning support statuses, and if we are married it to a vehicle and how many unlocks we have left.This is actually pretty important here. You can only use this device on one truck at a time. Once you custom tune a vehicle, the BDX will be locked to that vehicle, you can't actually plug it into any other vehicle and use it. In order to use it on a different truck, you have to convert the existing truck back to stock, that's gonna leave the paired status as "Unpaired," and then, you have unlocks that are gonna get used up as you pair it with a new vehicle.Then, lastly, we have our device settings here. You can make some basic changes to the audio and video on the device, you can also check for updates through here by clicking on Check for Updates, it'll do it automatically. You can cloud sync, if you have custom tune files to download. And if you want to, you can actually upload your data log files to the cloud, very convenient if you're working with a speed shop or a custom-tuning vendor.You have your Wi-Fi settings here. We've already gone over that, but again, same process, simply select Wi-Fi, it'll scan for the available connections, then you would connect with the appropriate passkey.You can also change the brightness on the screen for day and nighttime driving, you can configure the orientation of the screen from vertical or portrait here. Can actually change the theme, they provide some different color options. And power management mode, you can leave that on automatic, that will allow the BDX to turn on and off with the truck and the key being in the ignition, whether it's on or off. You can turn the audio on and off on the device as well if you don't like those little beeps and notifications. Can also turn the startup function to a particular screen or menu, you can have it go to the gauges automatically or you can have it go to the home screen automatically.But the most important function is our factory reset. Factory reset will completely undo any changes or modifications you've made to the device. It'll flash it back to stock, it will remove any files you've installed, it'll clear out your data log files, and it'll also undo any changes you've made to things like TPMS, or vehicle weight rating, or things like that. The only thing factory reset will not do is untune your truck and unpair the device. You do have to go back into Program Vehicle in order to do that. But again, if you wanna clear out everything else you've done besides the tune, factory reset is a simple once and done. And that covers all the device settings, it also covers all of our vehicle functions as well as all of our applications on the BTX.All right guys. So, as you saw, tuning your truck really only takes a couple minutes, and getting this thing completely set up is just as simple. That'll wrap up my quick little review and kind of install, if you will, of SCT's new BDX tuner fitting your 2014 up to 2018 5.3-liter powered Silverado or Sierra. Be sure to check it out more on the site. And for all things Chevy and GMC, keep it right here at
