JB4 Reviews

I've been a this app user for over 2 years and have thoroughly enjoyed it. That all changed with the latest app update. Upon automatic update, my old gauges and layouts were wiped out. Now, I'm forced to use one specific style of gauges, the text on the gauges has gotten MUCH smaller and it's hard to read due to the colors I'm now forced to use. Please add the other UI customization items from the previous version or allow us a way to install the previous version of JB4 . Thank you.

Very buggy. The email only support is very frustrating. I also highly recommend not purchasing the methanol kit until they can get lines that don’t leak and fill the trunk up with deadly and expensive methanol. The gains are good but I like peace of mind. I used to be an advocate for this app but with all the money they are making I don’t see it being applied to research and development.

Have had my this app installed for a couple days now and it’s been a blast. The problems lie mostly in JB4 . 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, JB4 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

Have only been using for a few rips so far and don’t have any major complaints, but immediately as I’m driving I notice a few things that in my mind should be in JB4 already and can’t be that hard to build out… 1. Name my custom maps 2. Let me see one or a few gauges at a time (screen layout) 3. Apple CarPlay!

I love JB4, but it has a quite a few bugs. It won’t let me stay connected to the tune for some reason even after restarting my phone and checking for updates for JB4 other than that, I’m satisfied, but please fix these bugs.

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!

I recently purchased this and for a product you can diy; it sure doesn’t come with a lot of information for the user. I went into a bio settings and it was just a bunch of stuff I don’t understand. Would be nice if I didn’t have to google all this information. Also, JB4 inverted and wouldn’t change back to the original position. Some help would be greatly appreciated.

It’s needed JB4 for my tuner. For the most part it’s great on the fly. I’m able to check my logs, switch my map, change my tune. Love it. Unfortunately I’m missing some parts of monitoring. I’m sure it’s due to availability and car. But I’m unable to get my Trans temp, oil temp, and some other. I also do wish there are more different styling gauges.

I’ve been using JB4 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.

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.

It’s an amazing app! A must have for this app 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!

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!

Everyone at this app 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!

So I’ve had the this app 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 JB4 . 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 JB4 . Other than that tho I absolutely love the this app tune and app. It makes such a difference from stock!!

The new update brings JB4 to the 21’st century. It’s great and let’s you choose exactly what parameters you want to see and match the colors to your car’s theme. Only thing we need now is Carplay integration!

There is an app developer who created exactly that. It’s an app called “OnTrack”. Let’s get his technology unto this app!

First off, JB4 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 this app, 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.

So far I really like JB4 and the this app. JB4 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.

First of all, having Bluetooth connectivity for the this app 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. JB4 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 this app, the Bluetooth interface will greatly enhance your investment.

I like the guys over at burger. They are pretty responsive on the forums and provide continuous support for JB4 . Just send them your logs on the forum and they will help you as best as they can.

The module is a boost controller so much of the tuning will be dependent on the fueling, spark plugs, and small adjustments in JB4 .

It’s basically the same stuff bmw is keeping from you behind a paywall. After all their engines are b48s,b58s and for the big spenders s55s . This beat paying bmw an extra 10k - 15k for a trim and horsepower increase.

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.
