How to connect the in-line fuel system
Some new comments as of 6/4/13:
PRICING is on the PRODUCTS page
new EZ-EFI 2.0 from 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
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!"
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.
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

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:
- 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.
* 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.
* 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
* 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".
* 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
* Works with nitrous or any form of induction with boost levels up to 60 PSI.
* Fuel system requirements are the same.
* Fully controls ignition timing and requires an ignition box such as an MSD 6AL
