How to control Valvetronic system and How does it work?

Vacuum Valves are featured in our valve systems. The negative pressure generated in the intake manifold of the engine board are utilized with vacuum valves and remote control module to open and close the valves as desired.
Control Module is included with all our systems, simply control by remote to set automatic, open and close modes.
CLOSE mode It helps the induction of car exhaust backpressure and increases torque at low rpm.
OPEN mode A free flow exhaust can bring Formula 1 sound and increase more horsepower at high rpm.
AUTO mode This mode will enable automatic open and close of the valves based on each car owner's individual preferences and driving habits.In this mode, you can set the valve to open and close by detecting various signals, such as boost, depth of gas pedal, rpm, etc.
