XFI Electronic Fuel Injection Systems 

Here’s the one electronic fuel injection system with truly revolutionary features and capabilities 

in an easy-to-use package. The FAST XFI system precisely balances fuel and spark, allowing 

you to fine tune like never before. The XFI system comes with easy-to-navigate software that’s 

completely configurable and allows you to set the parameters. Faster processing means no more 

flat spots in the power curve or settling for “close enough.” XFI is compatible with all common 

ignition types, including GM HEI, LT1, LS1, -2, -6, -7 DIS, Ford EDIS (4.6L & 5.4L), and Chrysler 5.7L, 

6.1L Hemi applications. 

Hardware Improvements 

The XFI uses the latest in flash microprocessor technology to deliver a significant increase in processing 

speed. This means the XFI can process, analyze and adjust four times faster than previous EFI 

systems. In addition, a surface mount component circuit board and billet ECU enclosure give the XFI 

superior durability. And to simplify installation, FAST offers engine-specific XFI Wiring Harnesses 

featuring clearly labeled connections.

The C-Com XFI Windows-based software is easy to navigate and incorporates several previously unavailable 

features, such as field flashable capabilities that enable you to download the latest software 

updates via email or directly from the FAST website. Stay current without ever removing the XFI from 

your vehicle. 

Special Features 

The XFI features Qwik Tune Technology, which allows ECU programming without a laptop. Preprogram 

up to four different EFI MAPs, and select the tune-up you need with the flick of an in-car switch. 

Optimize one setting for everyday driving, others for racing conditions and still another for improved fuel 

economy. Other features include on-board diagnostics, EZ Test Indicator Lights, five bar MAP sensing 

and controls for your power adder and torque converter. The XFI also offers enhanced data logging 

capabilities and memory for analyzing up to 8 additional monitored inputs. 

Easy-to-navigate C-Com XFI software

Optional System Upgrades 

Internal Data Logging (IDL) 

FAST offers an internal memory-based data logging option to give comprehensive data from 

all of your vehicle’s sensors and powertrain controllers. Available as a downloadable add-on for 

existing XFI owners or as an option with new XFI orders, Internal Data Logging 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. Internal Data Logging doesn’t require 

additional wiring harnesses or hardware and is an affordable option compared to purchasing an 

external data logger. Internal Data Logging is available with new XFI purchases, with or without 

Intelligent Traction Control , and in 8 or 16 injector versions. 

Intelligent Traction Control (ITC) 1 

One of the toughest challenges for drag racers is the loss of traction that comes from trying to put 

too much engine power to the ground with too little tire. The FAST Intelligent Traction Control 

solves that problem by using state-of-the art predictive software in conjunction with the most sophisticated 

electronics in the industry. Available with or without Internal Data Logging and 8 or 

16 injector versions, you can even send in your existing XFI unit and upgrade to a new one with 

Intelligent Traction Control . 

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 upgrades the XFI injector drivers to operate up 

to 16 injectors and includes the injector Y adapter.

Intelligent Traction Control is not legal in all sanctioning bodies/classes; check your 

rules before using.

Crank Triggers 

FAST turned to the OEMs to see what they 

trust in the way of crank triggers for their 400 & 

500 hp daily drivers. Until now, flying magnetic 

trigger wheels with bulky inductive pickups 

have been used with the risk of broken magnets 

or losing magnets at high engine rpm, 

which is detrimental to engine efficiency. But 

not any more. 

The FAST Crank Trigger is a magnet-free device 

with a wheel constructed from ASTM A36 

grade steel that is so strong that it is only .125- 

inch thick and is virtually indestructible. With 

the wheel being this thin, it not only weighs less 

but requires less space than competitors’ aluminum 

versions. The FAST inductive sensor 

is also much smaller than others on the market 

and is hermetically sealed with the connector

The FAST XIM Ignition Module lets you easily install the FAST XFI Fuel 

Injection System on many distributor-less ignition type EFI engines, including 

Gen III/LS, Ford Modular & Chrysler EFI Hemi. It’s a simple plug and play installation 

with factory type connectors that plug into your factory sensors. 

EFI Conversion Kit 

FAST Factory EFI Conversion Kits allow the installation 

of a GM Gen III LS1 PCM on any application covered 

by FAST Dual-Sync Billet Distributors (see application 

listing to the left). The distributor adapter wiring directly 

connects the Dual-Sync Distributor to your LS1-style 

wiring harness, and the ignition adapter wiring then 

mates directly to your harness and interfaces with an 

aftermarket ignition box through a simple, one-wire 

hook-up. A 1999-2000 Camaro/Firebird LS1 PCM and 

custom tuning are required. Benefits include fully sequential 

injection, ignition timing control and the ability 

to run a late model 4L60E or 4L65E transmissions.

• State-of-the-art magnetics improve injector opening times in order 

to yield faster throttle response 

• Precision ground pintle and wide spray angle both help to produce 

and deliver superior fuel atomization 

• Redesigned valve body resists clogging & improves hot starting 

• High-impedance injector models available up to 60 lb/hr for trouble-free 

OEM computer or XFI compatibility 

• Low-impedance 1 injectors available up to 60 lb/hr for maximum

Note: Low-impedance injectors can not be used with OEM computers 

2.550" (Center To Center) 

Choosing your Precision-Flow Fuel Injectors 

1. Take your target peak horsepower and multiply by 

• .5 for naturally aspirated • .6 for supercharged 

• .625 for turbocharged 

2. Take that figure and divide by the number of cylinders. 

3. Divide by .9 (for 90% duty cycle). 

This will give you the lbs/hr you will need from each injector. 

Example: 520 horsepower, naturally aspirated V8 

(520 x .5=260), (260/8=32.5), (32.5/.9=36) 

This application would require 36 pound per hour Precision-Flow Fuel Injectors 

(Part #303608). If the formula gives you a number that is not one of 

the injector sizes, the general rule is to move up to the next largest size.

The Biggest. The Baddest. The Most Powerful. 

GM LS manifold technology has been completely reinvented. With a three-piece modular design for easy disassembly 

and porting, a runner design that is longer and less restrictive and a larger air inlet to increase flow, these manifolds 

deliver significant increases in horsepower and torque – right out of the box. And with popular performance upgrades, 

the gains just get bigger. The LSX and LSX R 

 

manifolds are both designed from a state-of-the-art polymer material that, 

compared to aluminum, is stronger, lighter, easier-to-modify and much cooler – helping your engine avoid the powerrobbing 

“heat sink” effect common with aftermarket aluminum manifolds. Both manifolds retain all factory fitments and 

under-hood clearance requirements. 

The most powerful & durable Gen III and Gen IV LS manifolds ever built by FAST .


• Increases horsepower over stock 

manifold with no loss of drivability 

or low rpm torque 

• Incorporates high-quality polymer 

materials which resist “heat sink” 

effect of aluminum 

• Maximizes potential of other popular 

engine performance upgrades 

such as cylinder heads 

#54039

The patented FAST LSX 92mm Intake Manifold is a three-piece Gen III composite manifold proven to deliver increased 

performance without compromising bottom-end drivability or high rpm power. For both street and racing GM Gen III 

(LS1, -2 & -6) applications, this intake manifold is a bolt-on installation and is designed to work with the FAST Big Mouth 

92mm Throttle Body . The FAST LSX 92mm Intake Manifold maintains the performance gains achieved over stock 

intake manifolds with no loss in drivability or low rpm torque. While it delivers terrific performance right out of the box, 

it can be ported for even more flow. The intake features the added benefits of corrosion-free stainless steel assembly 

bolts, an improved throttle body sealing flange and o-ring gasket and threaded insert throttle body mounts that provide 

increased durability.

Big Mouth Throttle Bodies 

When it comes to improving your engine’s performance, increased airflow is a key ingredient. The FAST Big Mouth 

Throttle Bodies for the FAST LSX 92mm & LSX R 

 

102mm Intake Manifolds increase airflow through a series of innovative 

design changes and a slightly enlarged throttle opening. FAST also invested significant testing & engineering 

resources into optimizing cross-sectional flow and eliminating airflow turbulence, especially at part throttle operation. 

18 

In addition, these throttle bodies offer increased throttle blade thickness to eliminate 

deflection commonly found with other throttle bodies, especially those in 

boosted applications. A smoother operating offset blade pivot improves throttle 

response, and a beefed up linkage and dual throttle spring mechanism ensure 

total throttle control. The FAST Big Mouth 92mm Throttle Body will deliver bolton 

GM Gen III (LS1, -2 & -6) horsepower while the LSX R 

 

is designed to maximize 

potential performance upgrades on L92/LS3/LS7 engines.

LSX R 102mm Intake Manifold 

FAST engineers teamed up with airflow specialists at RHS to develop a polymer intake manifold for rectangular port 

GM L92/LS3/LS7 engines. Testing on a stock LS3 engine with a Big Mouth 102mm Throttle Body produced gains of 30+ 

 

horsepower and 25+ ft/lbs of torque at the flywheel over the stock intake. The LSX R 102mm Intake Manifold features 

a three-piece modular design that allows easy disassembly and porting. Extensive testing led to a runner design that is 

longer and less restrictive and gives the user the ability to remove individual runners from the manifold for modification. 

Constructed from the same advanced polymer material as the LSX 

92mm Intake Manifold, the LSX R offers a host of benefits over aluminum aftermarket intakes, including 

 

lighter weight, increased strength and improved heat dissipating characteristics. While the LSX R features a 102mm air inlet that is perfectly suited to the FAST Big Mouth 

102mm Throttle Body , it can also be used with stock or aftermarket 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on 

fitment that allows the use of factory accessories without modification or clearance concerns.

Electronic Transmission Controller 

Today’s electronically-controlled overdrive transmissions can offer excellent fuel economy and performance, but factory transmission controllers often fall short of the mark when 

it comes to street/strip or retro-fit use, let alone all-out racing applications. The revolutionary Transmission Controller by FAST overcomes the shortcomings of performancecompromised 

OEM electronic transmission controllers and elevates electronically controlled automatic transmissions to a higher standard of performance and tunability. 

Engineered to work with nearly any electronically controlled automatic transmission, the FAST Transmission Controller is fully-programmable and can be run either as a 

standalone unit – even with a non-computer controlled engine – or in conjunction with either OEM or aftermarket ECUs, such as the FAST XFI Fuel Injection System and 

carbureted applications. The FAST Transmission Controller will work with most GM, Ford, and Chrysler electronically-controlled automatic transmissions and includes a wide 

array of tuning options including load, gear, rpm and speed-based programming – all of which can be adjusted via a simple serial port interface with any Windows-based 

PC or laptop. Its ability to communicate with any ECU that supports CAN 2.0b devices means that the FAST Transmission Controller uses a simpler, easier-to-install wiring 

harness than most other aftermarket transmission controllers. The FAST Transmission Controller includes easy-to-use T-Com software, which allows simple plug and play 

transmission operation via several built-in programs, as well as custom tuning and programming, data logging and fault diagnosis. 

• Compatible with almost all popular GM, Ford and Chrysler electronic 

automatic transmissions

MaxJet Precision Carb Jets 

Often you will hear a racer say, “I made two jet changes, but the engine still didn’t run properly.” The reason 

for this relates directly to the jets being used. Other jets are mass-produced with a wide tolerance, then plated. 

Many of these jets use the same orifice size with the only difference being different angle tapers that supposedly 

change the flow-rate characteristics. Other jets also use a “slot” that requires a special, expensive tool to install. 

Ultimately, these slots become damaged and that damage creates a turbulence that severely affects the fuel flow 

as much as 50 percent. 

MaxJet Precision Carb Jets are available from 0.050” to 0.120” in gasoline jets and from 0.121” to 0.140” in 

alcohol jets. Sizes are in 0.001” increments and are compatible with all known racing fuels. MaxJet Precision 

Carb Jets are easily crossed over from Holley jets; simply find the Holley size that you’re currently using and follow 

over to the MaxJet column.

Frequently Asked Questions 

What are the advantages and differences between the new XFI unit and my older style “classic” FAST system? 

The XFI computer processor is four times faster than the “classic” system, allowing it to control more features simultaneously. The new XFI system uses a 104 

pin wire harness versus a 60 pin wire harness on the “classic” system; again, these additional pins allow more features and devices to be controlled by the XFI . 

Additionally, performance features that had to be purchased separately with the “classic” FAST system are now included with XFI at no additional cost. Just 

click on the features you want to control in the included tuning software, i.e. four stage power adder control, boost control, traction control, etc. The XFI can also 

be run in either batch fire or sequential mode. If you choose sequential mode, you will automatically have individual cylinder control of both spark and fuel. 

Can my older “classic” FAST system be upgraded to an XFI ? 

Due to design differences, the “classic” FAST system cannot be upgraded to an XFI . You will be required to purchase both a new ECU and wiring harness. 

With the new XFI system, do I need a separate data logger? 

The XFI can be purchased with or without Internal Data Logging (See page 5). If purchased without the data logging feature, the XFI will record to a laptop when 

connected. FAST also offers an easy-to-use external data logger that simply plugs into the XFI . The external data logger will record up to one hour of data and 

does not require the use of a laptop (See page 9). 

I have an XFI but I would like to have some of the newer options such as Internal Data Logging and/or Intelligent Traction 

Control. Can I add these options to my existing XFI ECU? 

The answer is yes. Internal Data Logging can be added as a download via e-mail, or FAST can send a CD with the necessary option file. To upgrade an existing 

XFI to Intelligent Traction Control , you will need to send in the ECU, and FAST will upgrade it with the option file and a new billet enclosure that clearly identifies 

the ECU as having this option. You must call first and obtain a Return Authorization Number before sending an ECU in for this upgrade. For more information 

about either of these upgrade options, see pages 5 and 6 of this catalog, call us at 1-877-334-8355 or email us at tech@fuelairspark.com. 

Can I have my XFI upgraded to ITC (Intelligent Traction Control ) without changing the enclosure? 

Each and every XFI that has the ITC option must be in a black billet ITC enclosure. In addition to this, there is an ITC-specific LED sequence that appears at key 

on. This allows tech officials to identify an ECU with the Intelligent Traction Control option. 

Is Intelligent Traction Control legal in my class 

ITC is not legal in all sanctioning bodies/classes. It is the user’s responsibility to check with his or her sanctioning body to make sure that an electronic traction 

control device is legal in competition. 

What hardware is required to use the Intelligent Traction Control ? 

The only device required to take advantage of our ITC technology is a driveshaft speed sensor. See page 7 of this catalog for driveshaft speed sensor kits. 

What’s the difference between “batch firing” or “bank-to-bank” vs. “sequential” systems? Which do I need? 

Batch fire systems fire all the injectors simultaneously. Bank-to-bank systems fire the fuel injectors in “banks”; half of them fire on one engine revolution and 

the other half fire the next engine revolution. A sequential system fires the fuel injector for each individual cylinder in the firing order of the engine. In most cases, 

bank firing will be fine, but if you’re using an extremely radical camshaft, high boost, or over 600 horsepower, you might find sequential to be a slightly better fit. 

It will usually make marginally more power and help some radical engines idle better.

an array of sensors including O 2 , TPS, and others. 

EFI - Electronic Fuel Injection 

A means of injecting fuel into the intake manifold of an internal-combustion engine using various types of fuel injectors that are controlled by an ECU (see below). EFI 

takes many forms, including throttle body injection (TBI) where a carburetor-like throttle body houses the injector(s), and port injection, where rail-mounted fuel injectors 

feed into each runner of the engine intake manifold. 

MAP - Manifold Absolute Pressure 

An engine sensor that measures intake manifold vacuum. Generally measured in bars, MAP data is used to measure engine load, which in turn allows the ECU to regulate 

engine behavior such as fuel supply and air/fuel ratio. 

O 2 - Oxygen 

Commonly used either as a shorthand term for an oxygen sensor or to describe oxygen as it is measured in engine exhaust gases. O 2 data is primarily used by an ECU for 

the purpose of regulating the engine air/fuel ratio. 

TCU - Transmission Control Unit 

A vehicle-mounted transmission control computer that varies transmission behavior such as shift points, shift firmness, downshifting and torque converter lockup based 

on engine load, vehicle speed and other variables. 

TPS - Throttle Position Sensor 

An electronic sensor, generally mechanically linked to the throttle body of an EFI engine for the purpose of measuring how far the throttle is opened when the vehicle 

operator steps on the vehicle throttle pedal. Throttle position data is generally expressed in terms of percentage and plays an important role in many ECU functions, not to 

mention determining when power adders such as nitrous are deployed. 

VATS - Vehicle Anti-Theft System 

An anti-theft circuit built into most GM fuel injection ECUs made after 1989. VATS must be bypassed with a special chip in order for some EFI engines to run when swapped 

from one vehicle to another. 

VSS - Vehicle Speed Sensor 

An electronic speed sensor, generally mounted in the output shaft housing of a transmission (a VSS may also be mounted at a wheel or other location). VSS data is used 

by both ECUs and TCUs for a variety of purposes, including torque converter lockup, downshifting, etc.
