As modifications are made to optimise engine performance, the factory fuel cut is often triggered by higher boost levels which activate a fuel delivery cut-off as a failsafe procedure. Symptoms of fuel cut are hesitation, bogging, and/or illumination of diagnostic indicators. 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. We have a large and rapidly expanding range of items for the Skyline- consumeables, performance upgrades, tuning items. Please check out the other items in our shop for brakes, water pumps, spark plugs, filters, fuel pumps, and lots of other essential par.
