Shadow digital electronic boost controller control the boost pressure and build intake manifold pressure by high frequency solenoid valve 24 times per second to increase total horsepower. It not only has a turbocharging display function to monitor the turbocharging value of the vehicle but also increase overpressure protection and lean burn protection to get engine protected when over turbocharging.

Shadow digital electronic boost controller action principle

The turbocharger uses the exhaust gas flow to make the actuator push the wastegate open to achieve the establishment and balance of the pressure in the intake manifold. Shadow digital electronic boost controller changed the mechanical of the actuator in order to push the conventional pneumatic wastegate open in electronic way. Electronic control helps build and balance the pressure of the intake manifold during acceleration. Advance turbocharging can indirectly affect the programming of the ECU, which will change the boost threshold of each gear engine speed. It also can eliminate turbo lag to a considerable extent. The ECU recalculates the mixing ratio of air and fuel to increase horsepower.

The digital electronic boost controller has function of monitor and control.

The difference between Shadow digital electronic boost controller and manual boost controller

The control unit of the digital electronic boost controller- 3-port boost solenoid can be applied to the internal and external Wastegate. Through the controller, it can change the solenoid valve gas passage and pressure. It can also monitor the pressure through the display and dynamically adjust the dyno tune at any time.

◆ Feedback unit:
Obtained the intake pressure through pressure sensor and send back to the operation display to calculate and monitor the current pressure value.

◆ User interface unit:
Allow the user to adjust the setting of the initial pressure, the expected boost range and the discharge pressure value.

◆ Control unit:
To control the frequency of the solenoid valve and the gas flow direction in each stage of the turbo.

As for the manual boost controller, the gas pressure is controlled by a simple mechanical structure (ball and spring style). Because of the spring characteristics, it is easy to lose elasticity when pressure is applied, which is not conducive to stable control pressure. It only can wait until the vehicle is stopped before they can be adjusted, and they also need to rely on a lot of experience and judgment. Because of the lack of overpressure protection, there is a greater risk of turbo being overpressure when using turbo pressure regulator.

The manual boost controller has machine principle.


  • Support Actuator and Wastegate mainstream turbocharging systems.
  • Ultra-high frequency solenoid valve, precise control of air pressure relief.
  • The right-hand drive operation interface can be switched.
  • OLED display screen enhances visual effects.
  • Combine with turbo gauge to monitor and adjust turbocharging at any time.


  • The air-fuel ratio meter can be expanded to detect and set the lean combustion pressure relief mechanism.
  • Adjust the Duty value to increase the maximum instantaneous pressure, breaking the original factory booster limit.
  • Adjust the Gain value and pull up the pressure-holding curve, to increase the turbo beneficial time.
  • Pressure forced to relief mechanism to ensure the safety of turbo and engine.
