Unfortunately, all criticism was ignored in the beta phase. 1. you can no longer send the logs via WhatsApp or other apps except the Mail app. This function was previously possible. Please change it so that it works again. 2. the folder has been completely removed. Why ? 3. WOT only is also completely missing. Please reinstall.
I use JB4 for a long time with additional ECU tuning. JB4 is just great. 🤗👍
This app does what it says on the box. The communication between my 2009 BMW 335i, the JB4 and iPhone 12 Pro works flawlessly without crashing. The app interface menus could use a little streamlining, but the gauge dashboard is functionally fine.
Habe vorher keine Probleme gehabt aber seit heute nach dem Update zeigt der mir nach Motorstart Fehler und die Motorkontrolllampe geht an wegen die Downpipes. Löschen kann man es auch nicht...
Die App an sich ist ganz gut aber der Support ist grausam Dann noch die Erstellung von Account funktioniert einfach nich Will mein Geld zurück Last die Finger davon
Es fehlt nur noch die Integration in Apple CarPlay. Dann ist die App wirklich perfekt.
Ich habe mir die App gekauft und zuzüglich das otg Kabel für iPhone 5s. Auf meinem IPhone ist iOS 8.3 installiert. Nun musste ich feststellen, dass iOS 8 kein otg unterstützt??? Versuche das iPhone, sowie das iPad 3 zurück zu daten schlugen fehl!!!! Knapp 30€ für den .....!!! Wieso wird die App dann überhaupt angeboten? Bitte um Hilfe!
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.
