Many vehicles have cooling fans controlled by the stock ECU. If a lower degree thermostat is installed, engine temp will still remain high at low speeds where there is little or no air through the radiator causing unstable engine temps. This unit can control one fan at two speeds, or teo fans at one speed, it can be set to turn on and off at any temp. It has a real time display for water temp, using the factory water temp sensor. A peak hold function memorizes and display s the max temp values. A built-in buzzer alarm function and blinking backlight, warn the driver if the set temp is exceeded. This allows driver to tell whether the temp is rising or falling by the rate that the backlight blinks.
The HKS FCD is an electronic device developed to properly raise the factory fuel cut level, on factory turbocharged vehicles, to a safe and higher predetermined point. As modifications such as intakes and exhausts are made to optimize engine performance along with utilizing a boost controller to further raise boost levels, the conservative factory fuel cut is often triggered by the higher boost levels which activates a fuel delivery cut off as a failsafe procedure. Symptoms of fuel cut are often expresses as hesitation, bogging, and/or illumination of diagnostic indicators. With the integration of HKS fuel controllers, or in certain cases where the factory fuel curves are very aggressive, an application specific amount of additional boost above factory preset levels can be accommodated. 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 as a simple integration on to the VPC/F-CON or factory ECU harness.
Warning: Due to the nature 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 strongly suggest a fuel supplement system or consulting a trained technician before the purchase and use of the FCD.
