HKS Fuel Cut Defencer

This electronic device is designed to safely raise the factory fuel cut level on turbocharged vehicles equipped with a factory ECU. When intake, exhaust, or other performance modifications increase boost pressure beyond the OEM limits, the ECU will trigger a fuel cut as a failsafe to protect the engine.

By adjusting the fuel cut threshold, this device allows your engine to operate without sudden fuel delivery interruption while maintaining stable performance under increased boost. It helps prevent abrupt power loss caused by fuel cut activation, making it an essential upgrade for vehicles running common bolt-on modifications.

DETAILS:
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 vehicle's engine or other mechanical parts
  We suggest a fuel delivery upgrade and consulting a trained technician before the purchase and use of the FCD
