HKS FCD (Fuel Cut Defencer)
The HKS FCD is an electronic device developed to properly raise the factory fuel cut level on factory turbocharged vehicles. As modifications are made to optimize engine performance, the factory fuel cut is often triggered by higher boost levels which activate a fuel delivery cut-off as a failsafe procedure. Symptoms of fuel cut are hesitation, bogging, and/or illumination of diagnostic indicators.
The electronic signal from the FCD will raise the fuel cut level to accommodate for the additional boost without triggering fuel cut and/or an engine diagnostic light. The FCD installation is designed to be easily integrated with the VPC/F-CON or factory ECU harness.
Warning: Due to the characteristics of this product, higher than recommended or unsafe boost levels may be attained by the installation and use of the FCD. This may result in severe damage to the vehicles engine or other mechanical parts. We suggest a fuel delivery upgrade and consulting a trained technician before the purchase and use of the FCD. |

HKS REV AD
The HKS RevAd is an electronic device designed to multiply a single digital 0-5volt signal. Many electronic air/fuel and timing controllers require a 0-5volt digital signal to operate properly. The HKS RevAd allows for one 0-5volt digital signal to control up to three separate electronic devices without any signal degradation. |

HKS SLD (Speed Limit Defencer)
The HKS SLD is an electronic device designed to eliminate a vehicles factory speed limiter. When competing on the drag strip or a circuit track, the factory speed limiter can hinder a vehicles performance. The HKS SLD is available in two versions: Type-1 is generally for vehicles equipped with a manual transmission and Type-2 is generally for vehicles with automatic transmissions. |

HKS PFC F-CON
|
HKS PFC F-CON
The HKS PFC F-CON is a plug-in fuel management system designed to supplement and refine the OEM fuel curve to maintain a proper air/fuel mixture when increasing boost pressure in turbocharged applications. The PFC F-CON optimizes the factory injector pulse width signal by recalibrating information obtained by both the PFC F-CON absolute pressure sensor and the OEM engine control unit (ECU). Each unit is application specific and includes a preprogrammed ROM for a particular performance stage. --- A Fuel Cut Defencer (FCD) is also included in certain PFC F-CON kits to override the factory fuel cutoff. The PFC F-CON offers easy integration via a plug-in vehicle specific wiring harness and a compact pressure sensor. If additional adjustment of the PFC F-CON is needed, fine-tuning can be performed via the plug-in HKS Graphic Control Computer (GCC). |

HKS AFR (Air Fuel Ratio Regulator)
|
HKS AFR (Air Fuel Ratio Regulator)
The HKS AFR is a fuel-adjustment device that regulates the air/fuel ratio by changing the airflow voltage output to the vehicles factory computer. The AFR was designed for vehicles that are lightly tuned (intake, exhaust system, etc.) and need only slight fuel adjustment. The 12 setting adjustment indicator allows the user to enrich or lean the stock fuel settings by approximately 1.0 A/R point in either direction (richer or leaner).
Type-D is designed to work on vehicles that utilize a pressure sensor.
Type-L is designed for vehicles that utilize an air flow meter. |

HKS Injector
|
HKS Injector
As boost pressure is increased on forced induction vehicles, the amount of boost that can ultimately be used is limited by the constraints of the engine and injector capacity. When OEM injectors reach their maximum capacity, they can no longer flow any additional fuel for higher boost levels; Therefore larger primary injectors can be installed in the factory location and be controlled by an injector upgrade specific program of the F-CON iS or F-Con VPro system. HKS injectors range in size from 480 to 1000cc and are available in top feed or side feed. Rail type injectors are used on the factory fuel rails or on vehicle specific, HKS fuel rail upgrade kits or AIC Pipe kits. HKS injector harnesses and other miscellaneous injector hardware and fittings are also available for custom applications. |
