Unit itself is great. The app is great when it connects. But sadly that's far too rare. And the company doesn't seem to care. Doesn't matter if you have Bluetooth or hard wired set up either. Most users experience the problem where it just won't connect. And then randomly once ever couple hundred attempts it might work. If they ever care enough to fix this very real problem the JB4 will be once of the very best options for tuning tubo cars. But without being able to connect I can't recommend.
Does it's job very well with little issues. Occasional crash when pushing new tune settings in, and the resolution can get screwed up if you flip to portrait and landscape too many times really quickly. Every very minor bug is fixed with a restart of the app. JB4 Support is amazing. The system has made our 2019 VW rocket like it should have from the factory. It is loads of fun fine tuning your map bit-by-bit and getting more power, economy, and fun. Hands down recommend!
Works well, zero connection issues. I believe the placement of the Bluetooth adapter on the JB4 is the reason for some issues people are having. I placed mine where the install instructions recommend and have never had a single failure to connect. This thing makes a very noticable difference and increase the fun factor of driving my vehicle. I can't imagine driving without it now. Zero fault codes because of the JB4. Worth the money and definitely go for the Bluetooth/app combo.
