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.

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.

No CarPlay??? Seriously?. I spend $600 on the JB4 and another $28 on this app and I have to keep my phone out to see the gauges. Insane. Despite that, app works great. CarPlay is a no brained addition.

Works as expected. I use this app to set and monitor my JB4 install. Easy to install and configure, works every time.

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!

Oil temp font. Great app, as always, but the font size for oil temp on the bar graph is too small and does not match the other gauges. In case this matters, car is e82 with N55 engine.

Gauges and some preset tunes. So I’ve had the jb4 app and tune in my 2019 Volkswagen jetta s 1.4t 6speed since April. In the beginning all the tunes were there but now for some reason a few are deleted from the app. Also I can’t see a lot of the temp guages. I believe the only one that does work for this car is the water temp. It would be awesome if burger motorsports would do a software update for my car!! There hasn’t been any since I’ve had the app. Other than that tho I absolutely love the jb4 tune and app. It makes such a difference from stock!!

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.

Good when working. Installed for two days now the Bluetooth connection no longer works at all.

Great app but I would love a CarPlay app. Idk if Apple will allow it but a CarPlay JB4 app would be worth another 20$ from me.

Problems..Good…But Problems. Have had my Jb4 installed for a couple days now and it’s been a blast. The problems lie mostly in the app. Most, as in 90% of the display options such as rpm, gear, speed, etc. have not worked for me. But, things like boost, gps speed, ecu boost, oil temp, etc. have worked but will stop after a certain amount of time. Customization is great, but the graphs don’t work even after doing a log. Have a check engine light on, probably from my high flow cat for my F30. But, the app says I have no codes showing up so I can delete them. Watched every how to vid and no one is addressing my problems..maybe this needs another patch

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.

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.

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!

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!

Jb4. The app keep going backwards can y’all update that is does it to me every time

Great Support, Great App!. Had an issue connecting to the device, but Chris was able to get me situated quickly!

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.

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!

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!!!

Great customer service. Love the app, but the customer service behind it even more !

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?

Essential app. Great app for the BCS JB4 users, but please drop the blue font with black background... its nearly impossible to see

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.

Can’t connect to server. Says unable to connect to service can’t even log into my JB4 account

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 ?

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.

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

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

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

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.

Stopped working. Since the update the app will not connect to the jb4. Don’t waste your money till fixed!

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.

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!

Great support. The owner emailed me to help me with my problem that blew me away.

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.

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.

Won’t go past “handshake “ on either of my devices. On second unit and no change. At a loss

CarPlay. Please add this app to Apple CarPlay. It would be nice to use my car’s screen to see my gauges as opposed to my phone.

Support. Great support, even at night or holidays. These guys were there to give me support. Thank you so much.

Does not work well.. App constantly cannot see devices, gauges constantly stop working randomly. Since last update cannot connect to tuner no matter how much troubleshooting. For how much this device cost and then to have to pay extra money for the app and then it hardly works (1 year or use…) I’ll be selling this crap tuner. 2019 Raptor.

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!

Worth the buy. You might think it’s a lot at first but when you actually use the app and see it’s capabilities it’s all worth it.

Using this app & Bluetooth wireless connector. While using this app & Bluetooth connecting, having issues some errors of sings, ignition problems, freezes up, or can’t read the gauges properly. I would not recommend JB4 tuning. Low quality product

Crashing. After the recent update I am having crashing issues when customizing my gauges. Please fix! 🙏🏽

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.

Great app. Love the app just wish it had CarPlay capability!

It works most of the time.. I’ve been using this app for about 3 weeks now and have had to delete it and download it again twice because the text on the goes inverse for no reason and won’t switch back. Other than that it does what it’s suppose to do.

Keeping the app updated. The overall experience of the app is good however I’m surprised to why the developers do not release the capability for apple CarPlay

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!

Works as advertised. Works well but would be good to have a CarPlay option.

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.

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.

more optimization. Needs more iphone x optimization

Really useful. It's a must if you have the JB4. I use it daily to clear codes or change the map settings. When I had issues, technical support was awesome everytime. Thanks for the good work guys!

Great app. The app works well and connects on every launch. Wish it read more codes on the Infiniti’s

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.

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.

Car play. We need car play support please

App keeps showing in Mirror image. Not sure if anyone else is having an issue, but I have to keep deleting the app and reloading as when I turn on it keeps giving me a backward or mirror image. Will update rating when this gets figured out. I’m using an iPhone 14 pro max.

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

Limited gauges. As JB4 uses odb2 and clear codes I would think I could get temperature gauges another OB2 readings for the price

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.

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!

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.

Awesome in every way. A++

Does what it says.. If you run JB4 this is a no brainer.

Great app. Makes logging and using the JB4 much easier. I have the Rev2 kit on my car and could not be happier!

Great app!. Love the app works well. Only thing is I tend to have a android phone at hand every now and again for other things. Was hoping to some how connect my purchase here to google play store on my other device? Let me know if that is something that can be done!

App double charged me. Charged me $52.98, not advertised price. Can you please explain? I’ll correct once answered

“Must buy” if you have JB4!!!. I’ve got an LCI E90 335i w/the N55 and I wish I got this app sooner. Using the app is so much easier than steering wheel controls. Highly recommended!!! Miles of the support team was super helpful and prompt! Highly satisfied with my app purchase.

Major flaw. Needs security. There is nothing to stop someone else from connecting to your car and changing crucial settings causing damage.

Awesome. It's money well spent!

Works great!. Works great with the JB4. Connects and works without hiccup.

False advertising. Does not work with the JB for USB. Doesn't say that it does not either. The day before Bluetooth was not compatible with my day before and there was no clarifications online about that either. Overall such a waste of time trying to get this to work.

Works Great!. It works great, but it’d be better if it worked in Apple CarPlay.

Water temp and oil and trans read in F only. Hi Thanks for the update But i notice that JB4 app version 2.5.1 Water temp and trans temp still showing in F instead of C Even when units conversion option is selected Only one that goes to C is the IAT Will this be fixed soon? , please fix

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.

Great app with great support. Support behind the app is awesome

Jb4 Is No Joke Lol. It's a big yes For me !

Why I hate this app. You can’t connect ever wouldn’t recommend to anyone

JB4 apps. I good like to return the JB4 apps

AMAZING. Best option out there. Everyone loves it, except all the v8 guys (mustang)i blow pass! This defines, on the fly tuning

App needs updating. This app needs an overhaul from top to bottom. The UI is very unfriendly. For the price of the app, it'd be nice fnthe developers atleast made the app look good

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.

Wont let me create an account to connect. Please help? On iOS !

Doesn’t connect. The app does not connect to the jb4, it keep asking to select the type of engine

Fraud. This app is a joke. Charged me over $30. Already called my credit card company and for a non payment and fraud by the app creator. Don't buy it!!!!

IS THIS APP STILL ALIVE?. No updates whatsoever? Paid $30+ garbage

Country Check for Passive Delete?. No thanks.

Jb4 2020 Kia Forte gt. I’m in love with the jb4 and having a blast on map 2. It’s a huge difference from stock. Customer service has been fantastic as well. App is very easy to navigate through. Would definitely recommend going through them.

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.

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.

Great app but needs CarPlay support. CarPlay support would make it perfect!
