JB4 Mobile Positive Reviews
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..Version: 2.5.5
Problems..Good…But ProblemsHave 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.Version: 2.5.6
Gauges and some preset tunesSo 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!!.Version: 2.5.6
Incredible SupportFirst 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..Version: 2.3
New Stinger User SuggestionSo 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..Version: 2.4.5
It’s more than performanceFirst 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..Version: 2.4.3
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..Version: 2.4.6
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!.Version: 2.4.6
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!.Version: 2.4.5
Awesome data loggingLove 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!.Version: 2.3.4
A must haveIt’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!.Version: 2.3.8
Great app and a must have with the JB4App 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..Version: 2.3
Oil temp fontGreat 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..Version: 2.5.2
Superb customer serviceI 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..Version: 2.4.6
ResponseHad 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..Version: 2.4.6
Connecting issuesI 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 ?.Version: 2.4.5
Good platform- fast response to issuesThe 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..Version: 2.4.4
WonderfulLove 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..Version: 2.4.3
Worth the buyYou 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..Version: 2.5.2
Amazing AppThis 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!.Version: 2.3.8
JB4 is garbageIt’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..Version: 2.3.5
Great customer serviceLove the app, but the customer service behind it even more !.Version: 2.5.6
SupportGreat support, even at night or holidays. These guys were there to give me support. Thank you so much..Version: 2.4.6

Jb4The app keep going backwards can y’all update that is does it to me every time.Version: 2.5.4
Keeping the app updatedThe overall experience of the app is good however I’m surprised to why the developers do not release the capability for apple CarPlay.Version: 2.5.5
App is greatApp is great but greatest is the customer service, I’ll keep an App or a business near just because of that!.Version: 2.4.5
Great Support, Great App!Had an issue connecting to the device, but Chris was able to get me situated quickly!.Version: 2.4.5
Essential appGreat app for the BCS JB4 users, but please drop the blue font with black background... its nearly impossible to see.Version: 2.3
Great app but I would love a CarPlay appIdk if Apple will allow it but a CarPlay JB4 app would be worth another 20$ from me..Version: 2.5.1
I love it best app everThis helped me gain power on my 3.0t Q50 very easy to use would recommend to anybody worth the money.Version: 2.4.5
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..Version: 2.5.6
Love love loveOk 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.Version: 2.5
JB-4 how do you register the app?Good if I can register it.Version: 2.5.4

Great appLove the app just wish it had CarPlay capability!.Version: 2.5.6
Works great!Works great with the JB4. Connects and works without hiccup..Version: 2.4.6
Really usefulIt'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!.Version: 2.5.4
Great appThe app works well and connects on every launch. Wish it read more codes on the Infiniti’s.Version: 2.3.3
CarPlay supportI’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..Version: 2.3.5
