The sound simulation system retains the strengths of the previous version while incorporating the following upgrades during optimization: a more compact size for easier user wiring, redesigned speakers, and optimized circuitry delivering greater power, higher sensitivity, and extended lifespan. Equipped with a Class D amplifier chip, it ensures efficient performance and high-quality audio output. Four screw holes on the rear housing accommodate DIY modifications.
Sound output is generated through real-time calculations based on throttle input values and throttle movement speed, combined with current engine RPM, to produce engine sounds that closely mimic real-world engine states. This is not a simple proportional output based solely on throttle input. Special sound effects (such as alarms and horns) can be independently controlled via the third channel on the player's remote controller.
