JB4 Group 8: Gen3B
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
Now includes the JB4PRO adapter and free app built in!
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 the optional wireless JB4PRO bluetooth 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. 5-year warranty.
