Group 8: JB4 Tuner for Audi A3 8V/ A4 B9/ A5 B9 (2.0T Only) - Burger Tuning

Audi A3 8V, A4 B9, A5 B9 Performance Tuner

JB4 Group 8

The JB4 is a plug and play Audi tuner that plugs into easy 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 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance.  Minimum power gains of 30whp and 45ft lb on 91AKI/95Ron

Unlike other tuning systems, the JB4 includes a fully programmable CANbus system, at-home upgradable firmware, and data logging capability. CANbus allows the JB4 to access engine data to take into account pedal input, throttle position, gear, engine speed, air/fuel ratio, fuel trims, ignition advance, knock, and many other factors and incorporate those into the performance mapping. It can also read/delete fault codes, incorporate unique safety features such as keeping boost pressure low until oil and water is up to temperature to provide proper engine and turbo lucubration and drop to a low boost map if the engine starts to overheat, run lean, excessively knock, or over boost.

The default JB4 map1 runs 3psi over stock peak and tuned maps, including stock and valet mode, can be selected on the fly using a BMS diagnostics cable or JB4 mobile smartphone adapter.  
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. 5-year warranty.

Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit or to your Windows laptop with the BMS data cable. Both options allow 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. A separate JB4 Mobile app purchase is also required.
