All New JB4 App

[Kia Stinger]

New for 2025 and exclusively for the JB4 tuning system!
The JB4 mobile app allows you to monitor and adjust your vehicle's performance in real time! The latest JB4 mobile update has an entirely new look and feel giving you much more control over how your data is displayed!



Packed with Upgrades!
Upgrades include having the JB4 performance map selection always active at the bottom of the screen, better organization of custom tuning data including intuitive sliders for table changes, and the ability to customize gauge layouts with themes.



Custom themes, Gauges, Colors, & More!
Using JB4 mobile themes you can customize data gauge types, sizes, positions, and colors, and even save different gauge layouts for different purposes or vehicles, including both portrait and landscape templates. Use histogram curves for data you want to monitor over time like air/fuel ratio or fuel trims, numeric gauges for more static data like temperatures and ethanol mixtures, and traditional dial gauges for ranged items like boost pressure or fuel pressure. In addition you can make certain gauges like boost larger and easier to see including adjusting how the gauge color changes based on its data. There is a ton of flexibility and in the future we'll allow you to share your gauge themes with friends!



Switch maps on the fly!
Ethanol and methanol injection compatible tuning maps, read/delete fault codes, view and record up to 40 gauges/engine parameters in real-time, boost by gear in 1st, 2nd, and 3rd can be controlled via the JB4 app for a perfect launch, and much more!



The JB4 mobile app is available for both iOS and Android and requires a JB4 mobile bluetooth adapter.

I have use the Beta now last year and it is great. More stable, fantastic possibility's for a tailor-made screen. Try it and you will like it!
