JB4 Group 9: Power gains of up to 100whp and 100wtq!

The JB4 is an easy to install plug and play tuner that attaches to sensors in the engine bay and works with your factory ECU tuning to remap boost, timing, and fueling for optimal performance and reduced turbo lag. Includes full SENT sensor technology required for properly tuning the latest Audi platforms. Includes full CANbus allowing the JB4 to access and incorporate all engine data in its tuning strategies, incorporate unique safety features such as keeping boost pressure low until oil and water are up to temperature to provide proper engine and turbo lubrication, and drop to a low boost map if the engine starts to overheat, run lean, excessively knock, or over boost. Includes fuel control for ethanol mixture mapping. Fully compatible with the optional wireless JB4PRO bluetooth adapter for on-the-fly map changes, data logging, firmware updates, and much more.
