HKS FCD Fuel Cut Defencer

HKD FCD Specification

When you increase the turbo boost pressure, the vehicle ECU often activates a fuel cut. This causes an electronic injection interruption if turbo pressure (considered dangerous for original engine) is exceeded.

The Fuel Cut Defender (FCD) allows you to adjust the fuel cut, by shifting or removing it completely. This ensures you can add further boost pressure, without having to go through a complete ECU change. The FCD is universal and comes with a manual detailing the wiring required to fit to most turbo gasoline Japanese vehicles (Toyota, Mazda, Subaru, Mitsubishi, Nissan, Suzuki, Daihatsu ).

Disclaimer: FCD does not control your mapping. Increasing boost without adequate modifications/settings can seriously harm your engine, which can result in failure.
