JB4 Tuner for Porsche Panamera & Cayenne

Power gains of up to 75hp and 75tq to the wheels on a stock Porsche! The JB4 plug and play tuner attaches to easy to access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag.

It features a 64mhz processor allowing sensors to be sampled 1000 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance. Unlike other tuning systems, it also includes a fully programmable CANbus system, upgradable firmware, and data logging capability.

Installation is very discrete, and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes. Made in the USA. Wirelessly Connect to your JB4: Grab our all-new JB4 PRO smartphone connection to wirelessly connect the JB4 BMW tuner to your Bluetooth 4.0 compatible iOS or Android device.

This option allows you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Our new adapter fits fully inside the JB4 enclosure for enhanced weather protection and a more streamlined look.

The JB4PRO Free app features an intuitive easy-to-use interface, help buttons, and advanced log analysis tools that can estimate the performance of your car and help identify any tuning concerns.
