Product Description

"Cooling by Radiator fan control" and "Speed limiter elimination." These are recommended to do before driving a circuit, and these were easily implemented before; however, the CAN communication system makes them difficult. Using an HKS original management system, it controls the CAN communication signal. Through this, the radiator fan can be controlled, preventing water temperature increases beforehand and safe-guarding the engine. The FSC is also equipped with a speed-limiter cut function, allowing the user to enjoy stress-free track racing even at high. HKS Fan and Speed Controller (FSC) is a lightweight and compact size device equipped with functions necessary for circuit/track racing.




  • NISSAN 350Z (2003, 2004, 2005, 2006, 2007)


  • Reliable monitoring of water temperature:
    Using the factory radiator fan operation signal and actual water temperature readings, the FSC also monitors vehicle speed conditions and controls fan speed accordingly.
  • Simple Wiring:
    A total of 6 wires need be done; including splicing into 2 CAN signal wires
  • Compatible with ECU version changes.
    Due to its external nature, the FSC functions are maintained even after dealer ECU flash version updates
  • Eliminate Speed Limiter
  • Control the Electric Radiator Fan
