Part #: 30401-KIT

As with the EZ-EFI Fuel, simply hook up the system, answer the Setup Wizard questions on the hand-held, and EZ-EFI 2.0 Fuel + Ignition tunes itself as you drive. Its eight-injector, die cast throttle body features late model OEM sensors for accuracy and durability, supports up to 1200 horsepower (the highest on the market), includes optional ignition timing control and is able to run E85 fuels while competing versions cannot. It flows more air than the first generation EZ-EFI throttle body due to an improved inlet, while a new secondary shaft throttle stop adjustment provides even more precise idle airflow adjustment and balance. Meanwhile, an industry exclusive and unique-to-FAST integrated fuel pulse damper creates ultra-precise fuel control. The EZ-EFI 2.0 Fuel + Ignition also incorporates needle-bearing supported shafts instead of bushings and an integrated fuel rail design with crossover for tighter packaging. Setup includes the market's fewest connection wires, including a high-quality wiring harness that is encased in a sleek mesh-type loom.T he EZ-EFI 2.0 has an updated hand-held as well, featuring the industry's first color touchscreen. Self-powered through the ECU rather than requiring an outside power source, it shares the same mounting points as the Garmin Nuvi GPS, meaning there are nearly limitless mounting options (suction cup mount is included with all kits). The hand-held has various advanced features including screen hide/sleeep function, expanded diagnostics and data screens, plus intuitive navigation. 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 in-tank, inline, high horsepower inline, return style and returnless style fuel pumps. 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.

This EZ 2.0 kit contains our EZ 2.0 ECU, touchscreen hand-held, and an in-tank 450 lph walbro fuel pump.
