WAKE UP YOUR BRONCO! JB4 Tuner for 2021 + Ford Bronco Install/Testing!

[@seanmp17]

Have you had any experience installing on a 2.3 manual? I heard the routing into the cab is different since there's a clutch pedal.

[@kevinskonieczny7708]

After talking to Jared today...I am sold.

[@NoNo_Notlikethat]

I was all for it, until they wanna charge for the app too. You already have to pay $140 extra for the Bluetooth phone connectivity. Charging an extra $28 is just dumb.

[@Lethalcamp]

From my personal experience it's worth every penny.

[@BurgerMotorsports]

The JB4 mobile adapter and app is $179 split between the two. It's done this way for customers who have multiple JB4 systems so they only need to pay for the app once and can then use it on all future models.

[@NoNo_Notlikethat]

@@BurgerMotorsports Fair enough. I like the idea of the product. Something about the pricing just doesn't sit right with me though. Maybe I'm just old school, or a cheap-ass 😆.

[@paulcook773]

How does this compare to the GOAT Sport mode? Would it make Sport mode even faster? I 'think' all but Badlands and Wildtrack have Sport Mode. It makes a HUGE difference over the normal drive mode.

[@Lethalcamp]

The JB4 device will enhance the vehicles performance in all modes. Nothing actually changes as far as what the modes do. Just better power/tq and performance over stock for each mode. Let us know if you have any other questions.

[@Wildtrax39565]

@@Lethalcamp Wildtrax has sport mode as well.

[@TheModestMallow]

Do we have any performance notations on the 2.3L? Just picked up my Mansquatch!

[@Lethalcamp]

Indeed we do. 50hp and 70lbs of TQ increase on the 2.3L with MAP 5. We posted all of the results on Bronco6G as well as on our site. Feel free to give us a shout if you have any other questions or need assistance placing an order. Thanks!

[@johncauffiel8386]

Super easy install. I think you forgot to tell the installer to plug inside the driver side printer type cable which is below the dash. Btw the app will cost you $28 bucks.

[@garymartin9765]

Have added an aftermarket air intake yet? If so, what kind of numbers are you seeing with both?

[@Lethalcamp]

We installed the Roush cold air intake on our first edition and then swapped it out for the Whipple one once we did the Whipple state 1 upgrade kit (tune, intercooler, intake). Personally I don't believe the intake is worth much by itself if anything. However on vehicles that are tuned and making more than stock boost levels the aftermarket intake most likely shines a little better since it's less restrictive than the stock one.

[@Logan0o]

So JB4 or whipple tuning ?

[@Lethalcamp]

Both are awesome and have seen very similar results. Although, the JB4 is limited to only horsepower and torque increases, where the Whipple has Auto Start-Stop disable, Raises the Speed Limiter, changes transmission shift points, and overall is a more in depth tune. I personally think the Whipple is well worth it, as there's a definite difference in pickup and the shift points, as well as the few other features it provides over the JB4.

[@BurgerMotorsports]

You can do a few things with flash maps that you can't with the JB4 like remove the speed limiter but remember any flash tune will also permanently flag the vehicle, while the JB4 can always be removed without a trace. The JB4 is also CARB approved for F150 models and hopefully Bronco models soon. JB4 also has excellent resale value and can be removed to transfer to your next vehicle as well.

[@raymondfink9580]

It would be awesome if you did a MPG test to see how it could be tuned for fuel savings

[@chaseshingoose4177]

ikr! exactly my thoughts for both the bronco and runner

[@holdenc2636]

Would I use the same jb4 you guys used for my 2.0 liter eco boost on my maverick?

[@Lethalcamp]

We have a specific JB4 tuner listed on the site for the maverick. If you head over to the site and type JB4 Maverick into the search bar the product will show up. Let us know if you have any other questions. Thanks!

[@davidrichardson5402]

Got question , does your Bronco have sport mode, just change mode ?? Thanks

[@Lethalcamp]

Our Bronco has all the available G.O.A.T. Modes, although, because it is a First Edition, it does not have Sport Mode

[@DanielGrows]

I don’t see any reason to use a piggyback when you can flash the ecu.

[@Lethalcamp]

Only Whipple has the capability of flashing the Bronco at the moment. It's a great cal and has the ability to change shift points, remove the top speed limiter, delete the auto start/stop feature and gives you the ability to change for tire/gear ratio changes. The only thing that people dislike about it is that once flashed the stock file is not saved on the Tomahawk device. So the Bronco can't be flashed back to stock by anyone other than the dealer. The concern for most is warranty. The JB4 isn't a flash and is plug and play so it can be installed and removed at any point without any trace on the PCM. You also have 5 maps and the ability to change them on the fly with a trick phone app. You can easily datalog with your phone too. Hope that explains why people choose to go with the JB4 instead of the full flash from Whipple.

[@_asq14_12]

Guys do u know any other mods that can help the bronco go increase horsepower and torque

[@Lethalcamp]

Intake, tune and exhaust are the ways to get more HP out of them. We still don't have any turbo upgrades available but when they are finally released that will be the best way to see really good gains over stock.

[@frankbenedetto]

What’s the best intake and exhaust to match with this tune? Just ordered the Jb4 from your site!

[@freedomsrt8]

Does the JB4 stay on the last map input if you unplug from ob2?

[@Lethalcamp]

Yes, the JB4 will stay on the same map you were on until you use the app or a PC to change maps regardless of if the OBDII connector is plugged in or not. Let us know if you have any other questions. Thanks!

[@freedomsrt8]

@@Lethalcamp Thanks For the reply.

[@troyterry2403]

I already have a pedal commander in my 22 wildtrak sasquatch 2.7. Can I still do the JB4 or does the pedal commander have to go?

[@Lethalcamp]

Yes, you can use both JB4 and Pedal Commander without issue!

[@severivers1419]

Are these maps safe to run without having to upgrade the gas?

[@Lethalcamp]

The JB4 has select maps (1-3) that can be run without mixing in E85. However, it is certainly recommended to use at a bare minimum 91 or 93 octane if available.

[@rudychavez5490]

Anything for the Bronco Sport 1.5?

[@Lethalcamp]

We have the JB4 for both 2.0T and 1.5T Bronco Sport! Burger Motorsport states you'll get roughly 60hp and 80tq increase, although results will vary depending on fuel types of course. www.lethalperformance.com/burger-motorsports-jb4-tuner-2021-ford-bronco-bronco-sport-400716.html

[@IMGONEIN60]

Will the JB4 affect any over the air updates??

[@Lethalcamp]

No, the JB4 will not be affected and the truck will remained tuned!

[@IMGONEIN60]

@@Lethalcamp awesome thanks 👍🏽👍🏽

[@texasbradley]

The installation is so invasive compared to the VR Tuner... I guess that's why the JB4 is a few hundred dollars cheaper..

[@Raven00714]

Something smells funny If it sounds too good to be true then it usually is

[@NazTramp]

Is this pointless for a stuck shift?

[@Lethalcamp]

Not at all! The JB4 would increase horsepower and torque regardless of transmission type. If you're looking for a little more power to the truck, it would be well worth it.

[@user-yq6ov6ow7l]

Wow that’s a pathetic increase. (Not saying it’s the fault of the tuner as they are probably working within their parameters) Bronco is so i unbelievably slow compared to what it should do if you factor in the motor it has and the weight of the vehicle. I’m thinking that this tune doesn’t dive deep enough and you really need full ecu and tcu access. Seems like it launches really weak which is likely torque management. Makes no sense that the f150 with the same motor is way faster. f150 with a tune is a whopping 2 seconds faster 0-60 with the same exact motor. F150 is also a much larger vehicle even though they weigh about the same.
