EZ EFI
30226-06KIT

Self-Tuning Throttle Body Injection Kit 4150 Flange 

The next generation of the world's simplest self-tuning fuel injection system is here. Designed for all applications making up to 550 horsepower, the EZ-EFI Fuel system easily bolts onto any carbureted or multi-port application, making it the easiest EFI system you will ever install. Simply hook up the system, answer the questions from the Setup Wizard on the color touchscreen hand-held unit, and the system will tune itself as you drive. 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 errors (including overheating) or be used as a shift light. An updated wiring harness features a premium loom, added protective fuses and a streamlined design, while the ECU hardware has been updated to provide added protection against electrical/ignition noise and hardware damage. FAST EZ-EFI now features a die cast and black powder-coated four-injector throttle body with integrated fuel rails. It provides even better fuel distribution and more airflow than the original, and NO manifold replacement is needed. In addition to matching any 4150-style carbureted manifold, the EZ-EFI Fuel Self Tuning Fuel Injection System also works with your original carb-style throttle linkage and features OEM sensors, including standard GM versions available at any auto parts store. What’s more, it works with all ignition setups including HEI. For more aggressive applications, the EZ-EFI Dual Quad Upgrade Kit is capable of supporting 1200+ horsepower engines with dual quad carburetor-type manifolds. In addition, the Multi-Port Retro-Fit EZ-EFI allows owners of multi-port fuel injected applications to experience the benefits of EFI with no limit on horsepower because the system is based on each customer’s supplied injectors.

EZ 2.0 EFI
30400-KIT

EZ 2.0 Base Kit with Touchscreen and Throttle Body

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. 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.
The EZ-EFI 2.0 Throttle Body 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. 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). The hand-held has various advanced features including screen hide/sleep 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.
Base Kit Includes: Engine Control Unit (ECU), Color Touchscreen Hand-Held Unit w/ Mount, Fully Mesh-Wrapped Main Harness, Fuel Pressure Adapter Block & Sensor, Wide-Band O2 Sensor, Installation Hardware, and Chrome EZ-EFI Badge.

XFI Sportsman EFI Kit with 4150 Throttle Body
303001

XFI Sportsman w/ 4150 TBI

Use our proven C-COM software to tune your muscle car, late model, boosted, drag racing, road racing or street car. Designed for muscle car, late model street and sportsman drag racing engines, along with boosted and individual runner throttle body applications, the FAST XFI Sportsman Engine Control System is a bank-to-bank, fully software-tunable EFI setup.

It requires a laptop for tuning and uses FAST C-COM software, which comes packaged along with the necessary USB connectivity cable. Promax recommends the Optional eDash #301517 (see Below for details).

A user-configurable auxiliary input channel is included as well. The system offers both load-indexed Speed Density or Alpha-N fuel strategies. Most users will use Speed Density but the Alpha-N option is specifically added to serve sportsman drag racers looking for absolute consistency. The FAST XFI Sportsman System features full tables to monitor fueling, acceleration fuel, timing and air/fuel targets, while full function data logging is also included. It supports both naturally aspirated and boosted applications up to 5 BAR, is compatible with wet nitrous and has nitrous timing retard control.

Built-in CAN network support for the EZ-TCU, EZ-LS and XIM means users can easily plug-and-play those components with the included CAN wire. The FAST XFI Sportsman Engine Management System also features a Bosch wide-band 02 sensor, utilizes built-in diagnostic LEDs, a waterproof ECU enclosure and includes a premium, mesh-type, wire loom multi-port harness. Compatible with return-style and returnless fuel systems, XFI Sportsman is designed for use with high-impedance injectors and works with a variety of multi-port systems or either generation of the FAST EZ-EFI throttle body.

XFI Sportsman is conveniently configurable to work with FAST distributors, FAST crank triggers, EZ-LS, XIM or the RPM/tach signal from an aftermarket CD ignition box, HEI big cap distributor or included tach adapter.

The Sportsman XFI is also available as a stand-alone ECU to run Multi-Port systems in various configurations #303003

OPTIONAL SYSTEM UPGRADES

 Internal Data Logging (IDL) *INCLUDED w/ ECU #301003*

The internal memory-based data logging option gives comprehensive data from all vehicle sensors and powertrain controllers. IDL allows recording of up to 24 input channels and sensors to instantly assemble a comprehensive, real-time picture of exactly what is going on under the hood of your vehicle. Newly expanded controls feature a separate arming input option. It doesn’t require additional hardware and is an affordable option compared to purchasing an external data logger.

 Intelligent Traction Control™ (ITC)

Intelligent Traction Control™ solves the problem of lost traction that results from trying to put too much engine power to the ground with too little tire by using state-of-the-art predictive software in conjunction with the most sophisticated electronics in the industry. The feature includes user adjustable delay to ignore erroneous starting line activation data and separate output wire activation upon ITC triggering. Intelligent Traction Control™ is not legal in all sanctioning bodies/classes; check your rulebook before ordering this upgrade.

 16 Injector Option

The 16 injector option is available for already existing XFI™ units by sending in your engine control unit and also for brand new XFI™ purchases. This allows the XFI 2.0™ injector drivers to operate up to 16 injectors and includes the injector Y adapter.
