Julio Esquilin - 4 star for now!
App is easy to use but it will be more useful if it have car play compatibility!!! Having all that info in ours car infotainment and make changes on the fly whit out touching the phone will be fantastic!!!! Other than that i love it!
C5ct - Update back to 5 stars.
Edited. Back to 5 stars. Donnie fixed the graphing issues and is back to normal. Anyone that does not like the latest update. Try the revised one on the TestFlight app. You may have to ask for a TestFlight invite.
Please revert back to the old version. The update is terrible. Graph graduations are better at 5, graph buttons overlay on phone icons take multiple presses to close graph? Let us scroll to the end of the graphed log, pop up for detailed graph info back to normal as well. All around update makes this app worse. I’d give it 5 stars the way it used to be. Icon legend is harder to read. I’ve emailed you during the test flight version that it was bad.
FallbrookMac - Incredible Support
First of all, having Bluetooth connectivity for the JB4 has been a valuable enhancement. When I had a problem with the BT hardware, I sent the unit to Donnie and after a few email exchanges, he fixed the problem and sent me a replacement unit. The app quality is outstanding and support all the more so. It is amazing that there is such an outstanding product for a niche application. Just get it! If you already made the plunge to get a JB4, the Bluetooth interface will greatly enhance your investment.
Taco197 - New Stinger User Suggestion
So far I really like the app and the JB4. The app connects quickly via Bluetooth and I haven’t had one issue after a week of use.
Something I’d like to see is multiple gauge screens to scroll through, similar to the Ultra Gauge app if anyone is familiar.
That way, my most used gauges are on the first page and gauges I reference less like map, temps and waste gate data could be easily accessed by a swipe rather than having to temporarily reset a more utilized gauge.
ELITE THUNDER - It’s more than performance
First off, this app is amazing. It brings the driving experience to a whole new level. Not only that, but just a few days ago, a mile from my house, I blew an upper radiator hose. With the aid of the jb4, I was able to monitor the coolant temp (not available on a stock 335) and safely drove home without fear of overheating. I installed an iPad mini, landscape view, above the center vents and very happy with everything. It’s just awesome, highly recommended.
Alopz96 - Worth the money!
Everyone at JB4 has been extremely helpful and quick to respond. Never had a aftermarket tuning company respond so quickly. You can tell they value every customer! Would 100% recommend if they have tuning for your platform!
LaTin.. - Awesome data logging
Love the real time data logging through your phone via Bluetooth. Makes things a lot easier to monitor. I always have it on whether I’m driving to work, going to the gym, test driving the car etc. Much more convenient than a laptop!
Osunar - A must have
It’s an amazing app! A must have for Jb4 owners. You can change maps on the fly via Bluetooth, in case you can’t find e85 and have to run on 93 only, it’s a cinch to lower boost a bit so you don’t damage your engine! All the different read outs are very accurate as well!
Anti- Zurditos - Great and fast Customer service.
I had the opportunity to resolve connectivity issues on two separate occasions. Both times customer service not only responded quickly but also addressed my concerns very fast. Two thumbs up to Miles Woodrum.
Jay Tolentino - Great app and a must have with the JB4
App is freakn awesome! So much easier to work with a phone than a laptop. Please change the background color as it’s too dark to read and if gauge selections can be adjustable from 1 to 6 gauges this would make it even friendlier to use.
Flexmoney18 - Connecting issues
I have recently got a radio and I downloaded the JB4. But its not connecting at all. It’ll keep searching till it eventually says something about connecting error. What could this be? Please help ASAP ?
Needs more colors free - Good platform- fast response to issues
The support team at the JB4 mobile group exceed expectations when it comes to turn around time for solutions to bugs and problems. Good interface for the Burger hardware.
K RY - Wonderful
Love the app and JB4 all together. Only thing to make it better is to make it Apple car play compatible so I can watch on my big screen rather than looking down at my phone.
RodCollier - Essential app
Great app for the BCS JB4 users, but please drop the blue font with black background... its nearly impossible to see
Matt 13F - Superb customer service
I am on my second vehicle with JB4 and I can’t say enough about their customer service. Very responsive and quick to answer questions or resolve issues.
CntryClub007 - Amazing App
This app is awesome, can change between Methanol Injection and standard all from the phone. Can also log data for tweaking purposes. Clearing codes paid for itself already once. Great piece of kit!
CRmag1987 - Response
Had a good response time from the team with the small issue I had. Hope I can help test out any new features you will offer for the q50.
Rumplelstiltskin - JB4 is garbage
It’s so nice of Burger Motor Sports to hide the $30 charge for the iPhone application after you spend $150 thinking you’re good to go.
And don’t try to update the firmware because that will just ruin your unit.
TayAurelia - I Want A Refund
This app does NOT work on the iPhone 12. The jb4 doesn’t even show up in my Bluetooth list. I keep getting an error message saying the pin is invalid but it doesn’t even give the option to input the pin (I know my pin). If you have the new iPhone it’s not worth it. I’m requesting my money back from Apple support smh Gonna get a data cable instead!
Bill23S - Works as expected
I use this app to set and monitor my JB4 install. Easy to install and configure, works every time.
Awgd8 - It’s very expensive app / no partial refund for one month use.
Make sure you are dead set on keeping your JB4 kit since this app is none refundable once you buy it. You won’t be able to transfer it to another user like your friend also.
So If you decided to sell your new JB4 tuner kit, count this app cost as your extra loss.
Joeytopr - App is great
App is great but greatest is the customer service, I’ll keep an App or a business near just because of that!
Brody810 - Great Support, Great App!
Had an issue connecting to the device, but Chris was able to get me situated quickly!
Fernan16v - Support
Great support, even at night or holidays. These guys were there to give me support. Thank you so much.
Lopez3.0t - I love it best app ever
This helped me gain power on my 3.0t Q50 very easy to use would recommend to anybody worth the money
Chadsipad - Don’t waste your money
Nobody at this company can be bothered to return an email. $28 for an app that doesn’t work. Don’t waste your time with this garbage. Buy a real tuner from ecutek they’ve actually provided me more support for this product than the actual company. HORRIBLE SUPPORT!!! DO NOT PURCHASE!!!
Snarf` - Username/password server fails
The app was GREAT until the username/password was implemented. Now I can't use my iPhone turned iPod for sole purpose of using it to connect to JB4 unit. Remove the username/password and this app will gain back its 5 star rating.
CYNOGENNINJA - Thank you for the update!!!
Thank you for update
Ferocious8855 - Log grouping stuck
The auto grouping in Logs is stuck, every time i disable grouping logs together so that it will log separately on each WOT the app regroups the logs , please fix
Darknight4" - Crashing
After the recent update I am having crashing issues when customizing my gauges. Please fix! 🙏🏽
Temp0717 - Worst customer service
Won’t call, only email. Takes a whole day to get one line replies. Going on day three and still can’t tell me why I’m having engine lights and issues with app.
VenomsDeath - Love love love
Ok im just getting into JB4 awesomeness. But this is way to easy. Im waitting for the catch but there isnt one. Great stuff my guy
Anic435i - Not working properly screen upside down and backwards can't read anything
I just bought this app I can't read anything it's all backwards upside down can I get some help please?
Greg21040 - Works Great!
It works great, but it’d be better if it worked in Apple CarPlay.
LauderdaleJJ - Stopped working
Since the update the app will not connect to the jb4. Don’t waste your money till fixed!
Samuel Ceja - Need to buy Bluetooth wireless connection
Didnt know i have to buy a addittional 140 dollar Bluetooth connection that i have money for so now im stuck with this app i spent 30 dollars on that im not gonna use
N8mndc - Works great!
Works great with the JB4. Connects and works without hiccup.
Diesel10_0000 - Refund
I’d like a refund please as I’m returning the JB4. Had for less than a week, and car has several error/malfunction messages now
Bananastud - Great app with great support
Support behind the app is awesome
Rpoffen - Great app but needs CarPlay support
CarPlay support would make it perfect!
Dabruce mom - Must have app for JB4 users
I really like this app and it works really well for the JB4 Connect Kit. The app should be included in the JB4 Connect Kit, but whatever. My issue with the price doesn't take away from how well this app works and how much easier it has made data logging and monitoring the JB4 for my M4.
Maikek pena - JB4 apps
I good like to return the JB4 apps
I hate jb4 - Why I hate this app
You can’t connect ever wouldn’t recommend to anyone
Tr1p13a - Good app, some flaws
Good app for data logging. No longer need computer jb4 app after. Yet there are some bugs and the 0-60 and 1/4 mile are no longer a feature. If they fix those then I would give it 5 stars.
Xach335i - Great app. Recommend for jb4 owners BUT.....
I belive this app needs to allow you to choose how many gauges you can display. That would be perfect!! Other than that the app is great works perfectly and would recommend it to every jb4 owner.
Frd135i - Outstanding support app for JB4
Don't know how I operated and tuned my car before this. Outstanding realtime display of what you car is doing and make tuning a breeze. Thanks for the outstanding product and keep up the good work.
CarbonX3M - Great app
Wish it was included in the cost of the JB4Connect Kit, but anyway, it's a great app. Can do all the stuff the burger software on the PC can do plus more. Occasionally the readings glitch, but I'm sure Donnie will figure out why and fix it.
Sanchezable - Great tool
Love using the app. Updates I hope to see. A gauge for fuel economy (miles per gallon). Add more of the steering wheel controls in the app for easier control. Also a eco map to maximize fuel economy, similar to eco and sport on modern BMWs.
FreshRal1art - Great app
Makes logging and using the JB4 much easier. I have the Rev2 kit on my car and could not be happier!
GT640 - Plug and play out of the box
As with everything BMS makes, this is amazing.
Works perfectly after a five minute install. Updated firmware on first login.
This would have cost thousands a few years ago!
Love you guys!
Enjoy high maximum transfers into more than 20 currencies while saving up to 90% over local banks! The cheap, fast way to send money abroad. Free transfer up to 500 USD!
Will Lotto - Awesome!
If you have a JB4, this app is worth every cent. I wish it would log real-time clock, GPS speed and g-force into the downloadable log files though.

BBBadi79 - Great app
The app works well and connects on every launch. Wish it read more codes on the Infiniti’s
Stefnept - Doesn’t work
I install it with the wireless app with iPhone 11. Worked few months and I tried to change map for valet and since, the app doesn’t work.
I tried to update and it’s even worse. The car don’t want to go faster than 20 miles/hr.
And check engine is on.
I’ve tried every things on n54tech.
I delete the app and the firmware cannot download.
I don’t recommend.
I cannot connect the wire the car don’t go.
I bought it for notting. Its big waste of time and money.
A good mecanic order it and installed it.
And when he order the wireless kit, they sent the bad kit for my car and had to complain seriously to get the good kit.
Never again for me.
Ddaversa - It works, but it’s lame.
Giving this a 2-star rating because quite frankly for the price it’s very disappointing. It does what it’s meant to do, yes, so it’s functional. But the interface for settings is crappy, there are UI glitches (i.e. can’t see the rpm limit value), it often crashes when I change my map, and honestly... my biggest complaint is, for the price... make this compatible with Apple Car Play! It’s literally a car app, and we all know it’s illegal to use our phone while driving, so this app is literally asking us to not follow the law in order to use it. I’ll gladly update my rating if they either give it support, but until then I find this app overpriced... but then again, that’s what happens when there’s no competition.
AlexanderR1 - CarPlay support
I’d really like to see CarPlay support added as well as an updated, cleaner UI.
Works well though sometimes it’s finicky to get connected. Still insanely convenient to switch maps on the fly. The connect kit really is a must have for any jb4 owner.
