The HKS fuel cut defencer 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.
