Description

Applications

• 2018+ Genesis G70 3.3T and 2.0T
• 2018+ Genesis G80 3.3T

This plug and play Genesis 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 64 mhz processor allowing sensors to be sampled 800 times per second using dedicated 10 bit digital to analog converters, ensuring smooth and powerful performance.

Unlike other tuning systems for the Genesis 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 4 psi 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 for the Genesis 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 0.022″. Alternatively replacement spark plugs can be used that offer a stronger spark and are more reliable than stock.
