FAST EZ EFI 2.0 Systems are now available!

ez efi 2.0 and FAST are proud to announce the new FAST EZ EFI 2.0 systems. The EZ EFI 2.0 systems build upon the popular attributes of their popular EZ EFI systems.

The Best Performing, Easiest to Setup, & Most Advanced Self Tuning EFI Kit on the Market.

No Experience, Dyno, or Laptop Required.

The original FAST™ EZ-EFI® changed self tuning fuel injection forever with the industry’s easiest carburetor-to-EFI conversion option. Now the EZ-EFI 2.0® has been upgraded with more features than ever before, while maintaining its ease of use that doesn’t require a laptop or tuning experience. It simply tunes itself as the user drives. 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 ignition timing control and is able to run E85, E98 and E15 ethanol-blend 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® 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 new high-quality wiring harness and a sleek mesh-type loom. 


The EZ-EFI 2.0® has an updated hand-held as well, featuring a color touch screen and an LED diagnostic feature that includes on-board diagnostics and EZ-Test™ Indicator Lights. Self-powered through the ECU, it shares the same mounting points as the Garmin Nuvi GPS, meaning there are nearly limitless mounting options. The FAST™ EZ-EFI 2.0® works with either generation of EZ-EFI® throttle body, multi-port systems, dual quad 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. The EZ-Ignition™ features an EZ-Solution™ option, meaning that it can work with most common ignition systems, while precision control requires a FAST™ distributor or crank trigger. The patent-pending EZ-EFI 2.0® is 100 percent designed and engineered by FAST™ and includes a limited lifetime warranty backed by the industry’s most extensive technical support team.

  • Higher flowing & higher HP capable 8 injector throttle body, supports up to 1200 HP!
  • Updated hand-held features the industry’s only multi-color high-tech touch screen display, with Garmin GPS-Style suction cup mount
  • Market’s fewest connection wires with sleek OEM quality wiring harness with mesh-type loom
  • Able to run E85, E98 & E15 ethanol-blend fuels as opposed to competitor versions that cannot
  • Compatible with in-line & return or returnless in-tank fuel pumps
  • Fuel pulse damper creates extremely precise fuel control that always allows a returnless in-tank pump fuel system to be used. No charts or questions to qualify for returnless like other competitors.
  • EZ-Solution™ option to allows integration with most common ignition systems
  • Works with wet nitrous systems; nitrous timing retard and special nitrous A/F ratio targeting
  • Includes limited lifetime warranty & backed by the industry’s most extensive technical support

EZ-EFI Self Tuning Electronic Fuel Injection

For years racers have known that FAST fuel injection systems are an excellent choice for their high revving, nitrous oxide, supercharger and turbocharger equipped rides. The FAST classic and XFI systems have also found their way onto many street machines. Though these systems served their users well, the Engineering team at FAST saw that many didn't have a need for the advanced functionality of the XFI systems, nor did they want to undergo a more lengthy install which may require them to replace their intake manifold and ignition systems.

Many prospective user's reasons for making the switch to EFI are the result of a desire to get the throttle response, mileage and power benefits that result from the ability to maintain the precise air to fuel ratios an electronic fuel injection system is able to deliver. In addition to delivering the aforementioned benefits, the FAST EZ-EFI systems also put an end to changing jets every time the weather and/or altitude changes.

While competing systems employ 20 year old OEM technology ECU's, awkward, costly and fragile mass air sensors, and narrow band O2 sensors (great for mileage, but not helpful for tuning for power), the FAST EZ-EFI offers dyno proven performance that may only be obtained from a wideband O2 equipped, speed density EFI system. Only the EZ-EFI system is worthy to wear the FAST brand name. In addition to its technical advantages, all FAST efi products are backed by the resources of the COMP performance group. If you were ever to have a question about, or problem with an EZ EFI product you can be assured that you will receive the service and support you need.

The EZ-EFI features an all new, patent-pending, self tuning control strategy. Simply hook it up, answer the basic setup Wizard questions on the included hand-held display and watch the system tune itself as you drive. Countless research and development hours were spent on a number of prototype test vehicles to develop a high-quality system truly worthy of the FAST brand.

Capable of supporting engines making up to 550 horsepower, the FAST EZ-EFI Self Tuning Fuel Injection System is a complete system which includes an ECU, wide-band oxygen sensor, wiring harness, fuel injectors, optional fuel pump kit and other assorted components, including an innovative 4150 flange Throttle Body. This Throttle Body delivers a total package approach for any 4150 (Holley square bore) type intake manifold. All necessary components are provided with the EZ-EFI kit, including appropriate fuel injectors and fuel rails. In addition, the EZ-EFI system works with original carb-style throttle linkage and is ready to accept all OEM sensors.

Installation of an EZ-EFI system can be completed easily in an afternoon and doesn’t require any EFI experience or expertise.
