Ratings and reviews

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.

App is nice when I can actually use it. When connected it never wants to read any of the gauges besides boost, it randomly starts "logging" but won't turn off, and it won't read codes. If everything worked they way it should the app would be phenomenal. It's kinda disappointing that I paid like $20 for an app to have the ability to read gauges, data log, scan and clear codes but the only way I can get it to work is by uninstalling the app and then reinstalling.

Not sure what happened with this latest update but I just wanted to work when I turn it on and it connects to my jb4. Now I only have one choice for a color scheme on my gauges and when I have the gauges on they don't stay on. They time out with my phone and shut off. The previous Edition would stay on if you had the gauges up.
