This plug and play KIA Stiner tuner attaches to two 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. 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 now comes with the Fuel Wires as part of the JB4 kit.

You may also wish to add the Data Cable or the Bluetooth Connect Kit for additional features.

Power gains of up to 100hp and 100tq to the wheels on a stock vehicle

Unlike other tuning systems for the KIA Stinger it also 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, 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 over heat, 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. Fuel economy during normal driving is unchanged. Compatible with all driving modes. Made in USA. 5 year warranty.

As is well documented the Stinger platform, both the 3.3L and 2.0L, is 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 than stock. See the JB4 Stinger forum discussion below for our latest plug suggestions and JB4 map guide.

JB4 Map Guide as of v5 firmware, updated 03.08.2018 (selected via JB4 Mobile/laptop interface. Map1 is the default map)

Map 0: JB4 disabled 
Map 1: 4psi over stock peak tapering to 2.5psi at high RPM. Default performance map suitable for all 91+ octane fuels.
Map 2: 5psi over stock tapering to 4psi at high RPM. Suggested for 93+ octane fuel.
Map 3: 6psi stock tapering to 5psi at high RPM. Suggested for high quality fuel including unleaded race gas, ethanol mixtures up to 30%, or high quality octane booster like Torco or Boostane. 
Map 4: Valet map, runs around half as much boost as stock.
Map 5: Up to 7psi over stock. For use with unleaded race fuel and/or E85 mixtures up to 30%. 
Map 6: User adjustable map. Enter value of boost over stock by RPM on user adjustment page.
Map 7: Up to 7psi over stock but without top end taper. For unleaded race fuel and/or E85 mixtures, and bolt on modification. 
Map 8: Progressive WMI (water/meth) map. Increases boost as a function of methanol flow & methanol boost additive. Holds boost low until WMI is flowing to avoid tip-in knock, and reduces boost as a function of WMI flow in the event of interruption like running out of fluid, leak, or component failure.
