HKS Standard Fuel Cut Defender (FCD) - 4501-RA002

$160.00

$160.00

The HKS Standard Fuel Cut Defender (FCD) is an essential electronic component for enthusiasts looking to increase boost levels beyond factory limits on turbocharged vehicles. Many factory ECUs are programmed with a safety fuel cut that triggers when the manifold pressure sensor (MAP) or air flow meter (AFM) signal exceeds a specific threshold. This unit intercepts that signal, clamping the voltage or frequency to prevent the ECU from initiating a fuel cut.

  • Prevents factory overboost fuel cut to allow for higher boost levels
  • Electronic signal modifier for voltage-based MAP or AFM signals
  • Adjustable dial for precise signal clamping calibration
  • Enables full use of boost controllers and upgraded turbochargers
  • Manufacturer Part Number: 4501-RA002

By preventing the factory fuel cut, the HKS FCD allows for increased performance without the ECU interfering with the fuel supply. It is recommended to monitor air/fuel ratios and ignition timing whenever modifying engine management signals for increased boost.
