FUEL INJECTION 101 Many times a second, a group of sensors

measure various engine and atmospheric conditionsconditions.

Just as fast, the Engine Control Unit (ECU) analyzes the sensor data and commandsanalyzes the sensor data and commands

the correct fuel delivery. Sensors also evaluate the accuracy of theSensors also evaluate the accuracy of the EFI commands and use the feedback to fine

tune future commands.

ADVANTAGES OF EFI More torque and power

Intake manifold can be optimized, improved control of fuel and spark, tunabilityspark, tunability

Improved throttle response and drivability No hesitation/stumble when cold No vapor lock when hotp Infinitely tuned versus tuned for one spot with a carb Easy starting, regardless of weather

Better fuel economy Superior tunability, Wide band feedback and control

Lower exhaust emissions Good for many reasons

Overall increase in engine lifetime Better running engines last longer

DISADVANTAGES OF EFI Complicated

Requires advanced knowledge of engine performance Tuning is difficult and expensiveTuning is difficult and expensive

Requires a dyno and countless test sessions Requires a laptop and the ability to use it Requires a professional tunerq p

Expensive EFI system, manifold, dyno time, laptop, tuner time

Cant see it Little black boxes and a lot of wires

Fear factor Horror stories of legend

Sanctioning bodies Many dont embrace or allow EFI

Design Objectives for EZ-EFI ELIMINATE the Disadvantages of EFI!

Infancy of Program EFI Guys banned from planning session!

EFI guys dont understand how Carb guys think CARB Guys led the planning and approval sessions!CARB Guys led the planning and approval sessions!

What do they want, what do they fear, what would get their interest

Initial Plan Easy, Easy, Easy No EFI tech lingo

N L ll! id h d h ld ll dj No Laptop at all! provide a hand held controller or use adjustment screws.

Make it work just like a carb; a 750cfm carb will work just as good on a Chevy, Ford, Chrysler, etc!y, , y ,

Delivery a very high value at a reasonable cost Absolutely no trips to a tuner, dyno, expert, etc

The EZ-EFI PlanE ll t P f Excellent Performance

EASY no expertise needed Self tuning*Self tuning

No laptop / No tuning needed Use existing carb manifolds

Compatible with existing throttle cables Affordable Price

Highly compatible Highly compatible Maintenance free

Support high horsepower

*That actually works!

What is REAL Self TuningWARNING: Many companies are claiming self tuning

Closed Loop Wide Band Feedback is NOT self tuning Limited block learn from closed loop is NOT self

tuningtuning Requiring a pre-tune or selecting a map to start is

a sure sign of inferior, inaccurate claim of self tuningREAL lf t i d t i t REAL self tuning does not require a pre-tune or map at all. EZ-EFI builds a map from SCRATCH!

The (Big) Hurdles

Proper fuel distribution from a throttle body Patented design

Properly functioning and capable self tuning Easy to learn, INCREADIBLY HARD to only

learn the good stuff and disregard the bad stuff Over 5 years of developmentstuff. Over 5 years of development.

Eliminate the disadvantages of EFI Keep it affordable Keep it affordable

What is BecameFAST EZ-EFI

Eliminated Disadvantages of EFI Available in single 4bbl, dual quad, and multiport REAL self tuning that actually works Capable of supporting up to 1000hpCapable of supporting up to 1000hp EASY, EASY, EASY

Installing EZ-EFIg

How Long Does it Take to Install?

Professional: 2-8hrs*Do it Yourselfer: A weekend

*Depends on application and fuel systemDepends on application and fuel system

Installing EZ-EFIgWhere is the time?

Fuel system this is the biggestFuel system this is the biggest time variable.

If the vehicle is already EFI based fuel If the vehicle is already EFI based, fuel setup is very quick.

Where is the time?Installing the Wide Band O2

All EZ-EFI kits include a weld-in bung and plug. The bung can be welded in at a shop and plugged for thebung can be welded in at a shop and plugged for the drive home, or it can be welded in to a header off the

car. FAST does NOT recommend clamp-in adaptors for

wide band O2. These may appear easy, but they are prone to leaking. Leaking exhaust will kill self-tuning
