Review & Install Video
Hey, guys. Adam here with americanmuscle.com. Today we're taking a closer look at dyno testing and installing the Diablosport inTune i3 Tuner available for the '09 to '14 5.7 Hemi-Equipped Challengers. Now we have with me the 13 RT in our shop, the 5.7, strapped down to the dyno to make some numbers. Before we jump into things, guys, I want to walk you through the dyno graph. Let's talk about what this thing made. We established our baseline run, we, of course, ran it with 93 octane in the tank and our 93 tune from Diablo, otherwise known as the Diablo tune. So let's take a look at those results.
Well, guys, we, of course, established our baseline run in our 2013 5.7 on the dyno here, 93 octane in the tank, completely bone stock, otherwise we walked away with about 346 horsepower, 377-foot pounds of torque at the rear wheels. We then, of course, uploaded our Diablo tune or the 93 octane tune, ran it under the same conditions in fourth gear, and walked away with 357 horsepower and 394-foot pounds of torque at the rear wheels. That's good for peak gains of 11 horsepower and about 18 torque at the rear.
Now, those numbers alone are pretty good from just a simple preloaded handheld tuner, but it gets even better under the curve. And the curve is really where things matter, that's what you feel in the street. And we're seeing 14 horsepower and 18-foot pounds of torque under the curve at right around 4,000 to 4,100 RPMs. Now, that's a really, really good sweet spot. That's low to mid-range power, accessible for you right at your foot, and that's what you'll feel. That's pretty good gains.
And honestly, the torque curve here is completely linear throughout the entire RPM band. We have 388 torque at the rear wheels at 40,000 RPMs. It goes up a little bit and then stays pretty linear until a slight drop off at the red line. So all together, guys, this is a very impressive graph that we're looking at, and I'm happy with the results. Guys, jumping right into this thing. The Diablosport inTune i3 Tuner is a preloaded tuner or a canned tuner, which basically means, right out of the box, it's got tunes loaded and ready to go. Good for 87, 91, and 93 octanes, again that Diablo tune.
Now, of course, maximizing everything, maximizing all potential, you want to run at Diablo tune, and that's what we've got on the dyno today and what we're installing. Now, aside from actually tuning the vehicle, which is not only gonna give you a better horsepower and torque numbers, it's gonna give you a better throttle response, acceleration, and honestly, just more enjoyable engine overall, whether it's stock or modified.
Aside from that, though, you're also getting a couple of other cool features including a DTC code reader. Now, DTC, being a diagnostic trouble code, otherwise known as that dreaded check engine light. Now, if the check engine light ever comes on, you don't need to go to AutoZone or Pep Boys or whatever to get a code reader to run and read your code. This you can plug right into your OBD 2 slot, it'll give you the code, a description, and you'll be able to clear that and get rid of the light just from this device.
Now, that's really useful, you don't need a multitude of devices in order to do different types of various activities. It's all built in right here on your i3. Now, this device also has data logging capabilities to make sure that if you have a custom tune, which you can save on this device, you can work with your local tune shop right on the device to save data logs, upload, take a look at, make revisions, and so on and so forth.
Now, the device itself here has built-in WiFi within this very small unit. Now, this is smaller than your average smartphone. It is touchscreen and has a full-color display and it's very responsive at the fingertips. It's actually a really cool device in the sense that it's a little more modernized compared to some of the handheld tuners out there.
This also has a new updated design over the i2, which is now being replaced by this guy. It's got some grips on the side here. You can plug in your USB right to the top here as well as a jack and then, of course, your OBD2 plugs into the bottom. So really straightforward, not a whole lot of buttons to get confused by, and overall a good option for guys who don't want to spend big bucks on a handheld tuner to get custom tunes but still want to make some changes to their vehicle to get more out of it.
So while it's not as involved and customized to your mods as a custom tune, it's still gonna make the difference as you saw from our dyno graphs. The device comes in right around 400 bucks, which is definitely a little bit easier on your wallet than a custom tuner. The install, I'm gonna give one out of three wrenches on our difficulty meter. Anybody can tackle this in the driveway at home.
The first time out of the box, it's gonna take a lot longer to load your tunes because there are some revisions it has to make to your ECU while also saving your stock file. But every single time you use it after that, it'll be done in about 10 minutes. So overall I'd give it 30 minutes start to finish on the first try. Now, I'm gonna show you guys how to do everything I just mentioned. We're gonna start by loading our tune and then I'm gonna show you those features.
The first step here in the tuning process is to grab the OBD2 harness, plug it into your OBD2 port under the driver's side dashboard right around the center there, and then plug the other end into your tuner. All right, once that's pulled in, grab that other end. This will go right into the bottom slot. Perfect. Now you can hit your ignition on and get started.
All right, once you plug in the device, you'll be greeted with the boot up menu and then a quick disclaimer, it's more of terms and conditions you just want to agree to. You'll hit yes to accept that, basically saying this is meant for performance, you're supposed to use this properly and responsibly, so on and so forth. So once that pops up, we'll hit yes, continue and go through the process. All right, so here we're gonna hit yes. And from the main menu you have three options, tune vehicle, scan tool, and settings. I want to jump right into tuning your vehicle. Make sure you hit the start-stop button if you have the button or put your key in the run position but don't start the engine. Just press continue once you have that done.
From here, you have three options, easy tune, advanced tune, and restore backup. Restore backup is not gonna be a selection for the first time but once it saves your stock file, that'll be there. Now we want to jump in and use the advanced tune to be able to fine-tune what we want. If you want to make it the absolute easiest as it possibly could, you can do easy tune, but advanced tune gives you a few more parameters to select. Now from here we want to hit tune select and, of course, we're gonna go right into the preloaded at 93 octane or Diablo tune. So we're gonna install standard tune, but under that, you have custom and parameters to modify. From here, options are gonna be Diablo tune or 93 octane, 91, modify stock, or skip control unit.
Now we're gonna go into Diablo tune, of course, you want to get the most out of this. So you want to hit yes on the selected tune. The i3 will now read a backup from the vehicle. It will save your stock file to the device and that selection I mentioned earlier, restore backup, would allow you to return to stock. But for now, we want to hit yes and have that saved.
Now, this is going to give us right out of the box here a quick notice, and it says the vehicle requires additional programming before a tune. The process can take up to 30 minutes to complete, ensure headlights and all other devices are off. Now, because this may take some additional time, the first time you do this, if your battery voltage is a little low, you might want to put a jump pack on it or a battery charger on it just to make sure it stays up and running.
But for the first time, it'll take a little bit longer, but after that first is out of the way, your tunes will be ready to go on the vehicles. So we want to hit continue and allow it to go through this process. We'll come back when it's ready to right tune. All right, it'll prompt you to turn the ignition off. Press continue, back into the run position, press continue.
All right. At this point, it goes right into writing your tune. There may be multiple stages, you can see this as stage one. You want to let it load 0 to 100 as many times as it needs to. It'll give you a notification telling you that it is complete. It also may ask you to turn the ignition off again and press continue and then back on. So you just want, you know, stand by, keep an eye on it. Do not unplug the device and don't turn off the ignition unless it prompts you to.
All right, so ignition off. Continue. All right, so you can see it's going through stage two. Again, just let it load 0 to 100, and we'll come back at the end. All right again, ignition off. Continue. Back into run and continue. All right, from here you can modify any parameters, apply your tune. We're gonna go right into applying the tune because modifying parameters gets into things like tire size, gear ratio, speed limiter, rev limiter, so on and so forth. We're gonna keep all that the same directly as it is on the Diablo tune and let it do its thing. All right, tuning complete. You can unplug it and you can keep it in the glove box, center console. Before we disconnect, I want to take you guys through some of the features of the device aside from tuning.
All right, now, from the main menu aside from tune vehicle, you'll have scan tool. Now if you click that and ensure that your key is in the run position, you'll be able to take advantage of a DTC code reader, essentially. You don't need another device to see what the check engine light's about if it comes on. What you'll be able to do is plug this in, go to scan tool, select show trouble codes, it'll read the code, give you a description and the code itself. You'll be able to clear the code.
And then under that is data logging. So the DTC is very useful, but being able to data log is gonna help with making any tune revisions you might want to take on any custom tunes that you have saved on your device. So if you want to take advantage of saving custom tuned files from your own personal tuner, you can do so on the device, data log, see what's going on with your performance, communicate that to your tuner and make any revisions if needed.
Not everybody is gonna take advantage of data logging, but for the guys who want to fine-tune a custom tune that's a good advantage to have with this device. Now, other than that, you're going into settings because there aren't a ton of different options with this device aside from the scan tool, data logging and tuning. You do have WiFi access, WiFi configuration. You can connect to a network. That way, if you do need updates or anything like that, you don't need to plug it into a laptop if you're in the vicinity of WiFi that you can access.
Under that is analog input set up where you can add parameters, modify existing parameters, delete parameters that you've already established, and you can restore any defaults for the tunes. Under that sound and display, there is a beep per se when you click a button on the device, you can turn that off, make the screen brighter, so on. And advanced options check for updates and tech support. If you're having any issues you can try navigating the menus on here to solve an issue or you can give Diablosport the call, and then if you have custom tunes, you can erase a tune there.
So that really encompasses everything that this device offers. We looked at advanced tune where you can make parameter modifications, that's really the only other option that you would dive into. So this point, that's your device. Well, guys, that's gonna wrap up my review, install, and dyno run up for our Diablosport inTune i3 Tuner for the '09 to '14 5.7 Challengers.
