FAST EZ-EFI version 2.0

 

This page was updated on 10/10/13

NEWS:
The EZ 2.0 system is now available for port injection.
Up to this point only the EZ 1.0 system supported port injection.
The FAST part number is 30-404 Kit and cost $1290.
Since injectors are slowly phasing out the older EV1 style injector connector the 30-404 injector harness assumes EV6 injector connectors.

The EZ-EFI 2.0 documentation can be downloaded by clicking HERE.
It's a rather large PDF file (~7 meg) so make sure you have a high speed internet connection first.

Comments: Read the documentation!  It's all in there!

Here are some pictures from within that documentation:

Some new comments as of 6/4/13:



* The kits containing the fuel pump kits, will include regulators.

* The new fuel pumps are VERY high quality.

* Ability to toggle gas or E85 by one touch on the handheld!

* Real time/live fuel pressure sensor by one touch via handheld. (only one in the industry)

* 10’ handheld cable included, this is an additional cost option with some others!

* Diagnostic LEDs on the ecu, akin to those on the XFI system

* More parameter adjustability…. such as programmable fuel enrichment tables for cold start, accel fuel, etc…

* Harness includes fuses for such things as elec fan, etc.

* New throttle body is DIE CAST here in the US, providing a very high quality part, with matching die cast valve covers and air cleaners.

* Progressive fueling technology, using 8 injectors. Only one in the industry! That's how FAST handles such a wide range of HP!

* 1150 cfm rating on the TB…highest in the industry.

* Raised throttle blade placement acts as 1” spacer, providing even more plenum volume, better fuel atomization, and better overall performance.

* Nitrous capability/adjustability built in, including fuel enrichment, and timing trim, all adjustable!

The new EZ-EFI 2.0 from FAST is the next generation of self-tuning electronic fuel injection systems designed for easy installation and operation.
This one also has distinctive looks to go along with advanced features.

* Still totally self tuning without a laptop, but certain areas can be tweaked if you want, such as start and warm-up fuel.
* 8 Injectors (single throttle body can support up to 1000 HP, if you have at least 9" vacuum at idle)
* New look (that I think is great)

* Controls ignition if you want - but not required.  Also works with timing wheels such as 58X or any of the new HEMI styles.
* Whole rack of new LEDs make diagnostics easier
* New POD looks more like a high end smart phone with an actual dashboard style graphics display.
* Support multiple fuel types and all Ethanol blends (but not pure Methanol)
* Will run with "dead head" fuel system (but I still don't recommend that)
* Does not support boost

"A single throttle body will support up to 1,000 horsepower (but you still need > 9" idle vacuum)
"And the die-cast throttle body with the integrated fuel rails, matte-black finish and bold stripes, looks great to me!"

Like EZ 1.0, the new EZ-EFI doesn’t require a laptop or tuning experience to set up the tuning after installation. The wiring harness to the ECU was even trimmed with fewer connections and given a sleek mesh-type loom. The ECU has also been updated with LED diagnostics, and there’s a new industry-first, full-color, touch-screen handheld programmer.

The new throttle body features needle bearings for the throttle shafts, instead of bushings. The throttle shafts are raised slightly to provide a little more plenum area under the throttle body, allowing the air-fuel charge to have a straighter path before entering the manifold. Feeding that air flow are eight injectors instead of the older 4.

The move to eight injectors was for horsepower, without having to revert to low impedance injectors.

2.0 included new transmission kick-down linkage

 

Programming pod is more like a smart phone now.  It actually displays a dahsboard

 

For those of you that need to know the difference between the EZ 2.0 and the XFI 2.0, the XFI is still the system of choice for racers or anybody that has low engine vacuum or running boost.  I know that FAST says the EZ system will work with aftermarket camshafts but you still need at least 9" of vacuum at idle for ANY fully self tuning system to work.

The following chart helps clarify the differences between EZ and XFI systems:

EZ - EFI Systems

* Uses high impedance injectors. High impedance injectors are the lower flow type.  4 Injectors limit the first version of EZ to about 550 HP.  EZ 2.0 (with 8 injectors) can go over 1000 HP.

* Self tuning and does not use a laptop

* EZ 1.0 does not support alternative fuels such as E85 or Methanol. 
* EZ 2.0 supports any Ethanol blend but not Methanol, and it cannot be switched between fuel types.

* Does not support forced induction or nitrous (either 1.0 or 2.0)

* Uses a high pressure fuel system (>=43 PSI) that return fuel to the tank.
EZ 2.0 will work with dead-headed fuel systems, but it's still not recommended.

* Injectors fire in the bank-to-bank mode.

* Version 1.0 does NOT control ignition and requires a good tach signal, such as would be available from an MSD 6AL Version 2.0 comes with spark control included.

* This system can be either the throttle body type or when used with port injection must be paired with a throttle body such as the 30-7603.  Versions 1.0 and 2.0 both do this.

* All self tuning systems need a good stable idle vacuum of at least 9".

XFI EFI Systems

* The XFI can drive any injector. Once you get in the higher HP range injectors will be the low impedance peak-and-hold type.  The XFI can handle up to 16 of any type injector.

* Fuel table is self tuning but requires a laptop to set other parameters.

* Supports any fuel type since it uses a "Fuel Energy Constant" parameter.

* Works with nitrous or any form of induction with boost levels up to 60 PSI.

* Fuel system requirements are the same.



* Can be bank-to-bank or fully sequential if a cam signal is available.

* Fully controls ignition timing and requires an ignition box such as an MSD 6AL


*
Port injection only.



* Will work with any vacuum level.
