The next generation of the world’s simplest self-tuning fuel injection system is here. Designed for all applications making up to 650 horsepower, FAST® EZ-EFI® Fuel features a new die cast and black powdercoated, four-injector throttle body with integrated fuel rails. It provides even better fuel distribution and more airflow than the original. It is made in the USA and features a secondary idle stop to help with idle adjustment. A color touchscreen hand-held also features a new-and-improved Setup Wizard. The intuitive program asks a few basic questions and then the EZ-EFI® Fuel System tunes itself as the user drives. No laptop or previous tuning experience is required. The hand-held includes a variety of display dashes, a clean and easy-to-use interface and an LED indicator that can alert users to any error (including overheating) or be used as a shift light. Finally, an updated wiring harness features premium loom, added protective fuses and a streamlined design, while the ECU hardware has been upgraded to provide added protection against electrical/ignition noises and hardware damage. FAST® EZ-EFI® Fuel kits are available in throttle body injection (with or without fuel pumps) or multi-port options.
