Product Description

The HKS 4501-RA002 Fuel Cut Defencer is an electronic device designed to raise the factory fuel cut level on turbocharged vehicles. When performance modifications increase boost levels beyond the factory's safety threshold, the ECU may trigger a fuel delivery cut-off as a failsafe, leading to hesitation, bogging, or illumination of diagnostic indicators. The Fuel Cut Defencer addresses this issue by sending an electronic signal that raises the fuel cut level, allowing for additional boost without triggering the failsafe.

This device is compatible with a wide range of turbocharged vehicles, including various Toyota models such as the Supra, MR2, Celica, Soarer, Cresta, and Starlet, as well as the Mazda RX-7, Lexus SC300, and Daihatsu Move. Installation is straightforward, typically involving integration with the VPC/F-CON or factory ECU harness. However, professional installation is recommended to ensure optimal performance and avoid potential engine damage.

Please note that the HKS 4501-RA002 Fuel Cut Defencer is not CARB legal and cannot be sold or used in California on pollution-controlled motor vehicles.
