The FAST EZ-EFI 2.0 Fuel + Ignition works with either generation of EZ-EFI throttle body, multi-port systems and Inglese throttle bodies and is compatible with multiple fuel pump options including in-tank, inline, high horsepower inline, return style and returnless style. Electronic fuel pressure measurement is standard on all kits, and each one works with a wet nitrous system, providing built-in nitrous timing retard and special nitrous AFR targeting. The EZ-Ignition can work with most common ignition systems, while precision control requires a FAST distributor or crank trigger.
