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 JB4 mobile for on the fly map changes, data logging, firmware updates, and much more. Installation is very discrete and it is quickly removed without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes.
