It's well documented the Kia and Hyundai platforms are prone to spark blow out at both stock and higher than stock boost levels. Fuel economy during normal driving is unchanged. Includes maps for 91 octane, 93 octane, and E85 (ethanol fuel) mixtures. Installation is very discrete and it quickly removes without a trace when needed. 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 smartphone adapter. The JB4 offers a lot more performance, functionality, and safety than your average performance chip. 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. CANbus allows the JB4 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. Unlike other tuning systems the JB4 includes a fully programmable CANbus system, upgradable firmware, and data logging capability. It's able to auto-detect between 3.3L, 2.0L, and 1.6L turbo engines automatically allowing for simple plug and play installation across the entire Kia / Hyundai turbocharged lineup!Ĭlick here for the JB4 Tuner for 2.5T, 3.5T, SmartStream, and K5 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. The JB4 is a plug and play Kia / Hyundai tuner that plugs into easy to 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. Often within the hour! Power gains of up to 100hp and 100tq to the wheels on a stock vehicle RIDICULOUSLY FAST SHIPPING! We ship the same day you order.
