The new JB4 PRO free app and Bluetooth adapter are the perfect connection companion for your JB4!
It starts with our newly designed Bluetooth adapter featuring a relatively simple, low-cost, high-power, and reliable BLE chipset. The new adapter is compact enough to fit fully inside your JB4 enclosure and powerful enough to ensure a consistent connection inside the car.
The all-new JB4PRO free app, which runs exclusively on our new adapter was designed from the ground up in-house for ease of use, simplicity, and reliability. Able to operate fully offline, it includes all the features you’ve come to expect from a JB4 app, including map switching, live data monitoring, auto logging, read/delete fault codes, firmware updates, setting changes, and more. We’ve also added useful help functions to describe what the settings do, performance metrics and analysis tools so you can evaluate your car’s performance, GPS elevation/speed as a logging channel, and often requested functions such as “restore default settings”.

The new JB4PRO adapter is compatible with most JB4 systems from 2020+. It is incompatible with E chassis BMW or older systems that require a separate power wire. Older systems can email a photo of their JB4 control board to admin@nvperfromance.co.za for compatibility confirmation. The JB4PRO app requires compatible JB4 firmware. Check your firmware notes to ensure it states “Added support for JB4PRO free app” or let us know if there isn’t compatible firmware posted yet for your application!
NOTE:Â The JB4 always remains on the last map/settings selected, you only need to connect if you want to change maps, monitor engine data, or change settings!
The new JB4PRO control unit fits conveniently inside the JB4 case.
