JB4 Mobile

Bad. As the title says. To be specific, there are very limited parameters that can be displayed. Most of the parameters don’t work. Regret it. Should have gone for a KTuner V2.

I like the guys over at burger. They are pretty responsive on the forums and provide continuous support for the app. 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 the app. 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.

I love this app, 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 the app other than that, I’m satisfied, but please fix these bugs.

The app is great, but it would be really nice to see CarPlay integration without having to use a device to force CarPlay or android auto. Please try to integrate that.

Can’t save adjustments be cause there’s no way to get keyboard to go away

It’s needed the app 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.

Can you please edit the app for compatibility with iPhone 15/15 Pro? It’s difficult to, for example, see the top menu bar in the edit area for the different displays. Thank you!

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, the app inverted and wouldn’t change back to the original position. Some help would be greatly appreciated.

The app isn’t working on my phone but works for my android

App cost $28 but hasnt been updated in a year. Burger motorsports is such a great company, with an insane amount of JB4s sold and installed today. Please make updates to the app, my biggest issue is the constantly disconnecting from my bluetooth.
