EZ-EFI for PORT Injection manifolds  -------------->

Most of you know that I love port injection and the benefits of running a dry manifold.

The EZ-EFI was a giant step because it eliminated laptop tuning which was intimidating to many people.  But it's throttle body injection.

Since the EZ ECU can drive 8 high-Z injectors,
FAST has an EZ-EFI kit for Port Injection!
This has the potential of changing the entire EFI landscape.  No tuning, self learning system, with all the benefits of port injection.

$2170 for the "master" kit that includes the fuel system (pump, filters, fittings, etc)

EZ-EFI for CARB replacement using your existing manifold  -------------->

* Haven't got an EFI manifold?
* Don't want to remove the manifold you have?
* Afraid of EFI tuning issues?
* Don't want to use a Laptop?

This system is self-tuning, meaning it does not require tuning experience or a laptop. Hook it up, answer the set-up questions on the hand-held display, and the system truly tunes itself. The EZ-EFI is a complete system including the ECU, wide-band O2 sensor, Map, IAC, wiring harness, fuel injectors, fuel pump kit (optional), and the 4150 style EFI Throttle Body. 

This system is designed for anyone with an existing 4150 type intake manifold. Everything comes with the throttle body, including (4) 65 lb/hr fuel injectors, and it works with the original carb-style linkage.  This system uses a is a full Speed Density algorithm so it is truly hands off.  The system starts rich and gradually decreases the VE fuel as you drive, resulting in almost a perfect tune.

I have personally tested this system against the other systems that are out there and the EZ-EFI was worth the wait.  It really works!
