It’s good, but could be better

The app works well. I would love it if it supported apple car play, so the gauges could been seen on the cars touchscreen, instead of the phone. Either way, great app so far, no issues.

Let me name my maps

Great app and has worked for me reliably for the 9 months that is r been using it. It’s missing an important, and likely easy to implement, feature. Let me custom name my maps. Every time I got to switch, I have to go find the reference for the map set I have and read through it. It makes the on-the-fly switching way more painful than it needs to be. I’d happily have submitted this as a feature request but the support links in the app page just push you to the JB4 forums. That’s not the same thing.

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.

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!!

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.

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
