HKS Fuel Cut Defender
Fits Most Turbocharged Models
4501-RA002
Overview:
The HKS Fuel Cut Defender is an advanced electronic device designed to raise the factory fuel cut level on turbocharged vehicles. When you upgrade components such as your intake or exhaust, or increase boost pressure, your vehicle’s ECU may trigger a fuel delivery cut-off as a protective measure. The Fuel Cut Defender prevents this by adjusting the fuel cut threshold, allowing your engine to safely handle increased boost without interruption.
Ideal for performance enthusiasts who have modified their turbocharged vehicles, this device helps maintain smooth power delivery and prevents unwanted fuel cut events that can affect drivability. It integrates seamlessly with factory ECU harnesses and popular tuning systems like the HKS VPC and F-CON.
Key Features:
The HKS Fuel Cut Defender offers reliable and precise control over fuel cut parameters to support your vehicle’s performance upgrades. Key features include:
- Raises the factory fuel cut level electronically to accommodate increased boost pressure.
- Prevents fuel delivery cut-off and engine diagnostic lights triggered by factory ECU failsafes.
- Designed for easy integration with factory ECU harnesses and HKS tuning systems such as VPC and F-CON.
- Supports turbocharged vehicles with upgraded intake, exhaust, or other boost-enhancing modifications.
- Compact and durable electronic design for reliable operation under demanding conditions.
- Helps maintain consistent engine performance and drivability during spirited driving or track use.
Installation & Fitment:
The Fuel Cut Defender is engineered to fit most turbocharged vehicle models without extensive modification. It connects directly to the factory ECU harness or compatible tuning system harnesses, ensuring a clean and straightforward installation process.
While installation is designed to be plug-and-play with no cutting or drilling required, it is recommended to consult a trained technician to ensure proper setup and compatibility with your vehicle’s specific tuning and fuel delivery system.
- Compatible with most factory turbocharged vehicles.
- Integrates easily with HKS VPC/F-CON and factory ECU harnesses.
- No cutting, drilling, or special tuning required for basic installation.
Important Usage Notes
Because the Fuel Cut Defender raises the fuel cut threshold, it may allow boost levels to exceed factory recommended limits. This can potentially lead to unsafe operating conditions and severe engine or mechanical damage if not managed properly.
Before installation, it is strongly advised to upgrade your fuel delivery system to support increased boost and to consult with a professional technician. Proper tuning and monitoring are essential to ensure safe and reliable operation when using this device.
