This plug and play Kia / Hyundai tuner plugs in to 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. It's able to auto-detect between the 3.3L and 2L turbo engines automatically allowing for a simple plug and play installation with no model specific software changes required. Unlike other tuning systems the JB4 includes a fully programmable CANbus system, upgradable firmware, and data logging capability. CANbus allows the JB4 to take in to account pedal input, throttle position, gear, engine speed, air/fuel ratio, fuel trims, ignition advance, knock, and many other factors and incorporate those in to the performance mapping. It can also read/delete fault codes, includes 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 4psi 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 smart phone adapter. Installation is very discrete and it quickly removes without a trace when needed. Includes maps for 91 octane, 93 octane, and E85 (ethanol fuel) mixtures. Fuel economy during normal driving is unchanged. Compatible with all driving modes. Made in USA. 5 year warranty. As is well documented the Kia and Hyundai platforms, both the 3.3L and 2.0L, are prone to spark blow out at both stock and higher than stock boost levels. At a minimum the factory spark plug gap should be closed to 0.026". Alternatively replacement spark plugs can be used that offer a stronger spark and are more reliable
