Multi-Port Retro-Fit Kit allows owners of existing factory or aftermarket multi-port fuel injected applications and intake manifolds to experience the benefits of an EZ-EFI 2.0 system with no limit on horsepower because the system is based on each customer’s supplied injectors.

The next generation of the revolutionary self tuning EZ-EFI has been upgraded with more features than ever before. Yet it maintains ease-of-use that doesn't require a laptop or tuning experience. As with the original EZ-EFI, simply hook up the system, answer the Setup Wizard questions on the hand-held, and EZ-EFI 2.0 tunes itself as you drive. New high-quality wiring harness with a sleek mesh-type loom uses commonly available late model OEM sensors for accuracy and durability.

The 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). Serving as the Setup Wizard initially, it then becomes an electronic gauge screen. The hand-held has various advanced features including screen hide/sleep function, expanded diagnostics and data screens, plus intuitive navigation.

Electronic fuel pressure measurement is standard on all kits, and all kits work with a wet nitrous system, providing built-in nitrous timing retard and special nitrous AFR targeting. EZ-Ignition features an EZ-Solution™ option, meaning that it is plug-and-play with FAST Dual-Sync Distributors for electronic timing control or can be used with an EFI distributor of your choice and a FAST Crank Trigger. Or the system can be used to control fuel only (Like original EZ-EFI) and be used with a standard carb-type distributor (Ex. HEI) where timing is set manually.
