This Quick Start Manual is designed to get you up and
running with the Go Street Kit and either the 40003 Fuel
Command Center or the 40005 Inline Fuel Delivery Kit.
The FiTech Go EFI System is the industry's most advanced throttle body EFI system and also the easiest to
install. It includes a very advanced Handheld Controller
but is also capable of being far more tunable than any

About your FiTech Go EFI System
The Fitech Go EFI System will bolt directly to any 4-BBL
intake manifold. To fit on a spread bore 4-BBL manifold
will require an inexpensive adapater plate to avoid leaks.
Note that the FiTech throttle body will bolt directly to a
spread bore 4-BBL manifold but may leak without the

adapter plate. Suitable adapter plates are available from
several suppliers such as Summit Racing (SUM-G1420).
The Fitech Go EFI System is self tuning once the simple
initial setup is performed using the Handheld Controller.
When the necessary initial inputs are made with the Hand-
held Controller the Go EFI System creates a base fuel
MAP to get the engine running. Then the self tuning programming will fine tune the MAP to produce optimum
power and performance. Through the use of a wide band
O
sensor the system can continuously make adjust-
2
ments in the fuel delivery to provide the correct air/fuel
ratio under all climate and altitude conditions.
The ECU (computer) is mounted on the throttle body
thus eliminating the necessity of remote mounting the
ECU module and the need for an unsightly harness
draped over your engine. Several sensors are also integral to the throttle body assembly including the throttle
position sensor (TPS), manifold absolute pressure
(MAP), intake air temperature (IAT), and a fuel pressure
sensor.
Initial Programming: This simple procedure is performed using the Handheld Controller. A laptop computer
is not required. This unit plugs into the throttle body ECU.
After a few initial inputs are made the Handheld Controller
can be removed or left connected. When connected, there
is a dashboard and gauges screen that will show engine
parameters in real time.
Fuel Delivery Systems: You may have chosen one of the
two optional Fuel Delivery System Kits from FiTech. Instructions come with each kit. If using other fuel delivery
components you must use a 30-micron filter ahead of the
fuel inlet fitting on the Fitech throttle body.
Wide Band O
Sensor: This is the key component of any
2
EFI system. Only one sensor is required. This sensor continuously monitors the exhaust gas mixture and sends
the information to the ECU where adjustments are con-
stantly made to maintain the air/fuel targets.
Trigger Tach Signal: The FiTech EFI requires an rpm/trigger reference to operate. This is obtained by a connection
to the negative post on a 12V coil. On HEI distributors,
this connection is made to the "Tach" terminal that is indicated on the HEI distributor cap.
FiTech #40003 Fuel Command Center
Fuel Delivery Requirements
FiTech offers two different fuel delivery options. One is
the 40003 Fuel Command Center. When using this option,
you can configure the system to operate on a returnless
basis. The other fuel delivery system is the 40005 Frame
Mount Inline External Pump. Using this pump the system
must have a return line. The Fuel Command Center uses
your existing carbureted fuel pump and fuel lines to deliver the fuel to the Command Center which is mounted
in the engine compartment. The only plumbing required
is from the Center to the EFI.
High pressure hose and fittings are supplied with this
kit to plumb from the Command Center to the EFI throttle
body. A 340 L/PH EFI pump is submerged in the fuel in
the Command Center sump tank. The Center also has a
regulator and fuel pressure gauges.
When using the 30001/30002 Go EFI kits, the Com-
mand Center is suitable for engines making from 200 HP
to 600 HP. Either fuel delivery system can be used with
these EFI systems. When using the 8-injector 30012 Go
EFI System and the Fuel Command Center, the system is
suitable for engines making up to 800 HP. When combining the 30012 Go EFI System with the 40005 Inline
Pump, it is suitable for engines up to 600 HP.
Note: If you have elected to use the Fuel Command
Center and your vehicle currently has a high pressure fuel
injection pump, it must be replaced with a low pressure
carbureted style pump. Note that vehicles equipped with
factory high pressure EFI pumps are not compatible with
the Fuel Command Center.
If you choose to use some other fuel delivery system
other than FiTech, it is important to make sure that you
confirm its compatibility with the FiTech EFI system. Contact the FiTech technical staff to check compatibility. Failure to do so can void your warranty.

Note the following special instructions:
• We recommend using the Fuel Command Center for all installations. A submerged pump is quieter and lasts longer.
• If using the Frame Mount Inline Fuel Pump, it should be mounted
s close to the fuel tank as possible and also as low as possible. It
a
should be within two to three feet of the tank. This type of pump is
designed to pump, not draw, and works best when gravity fed.
• Only use hard fuel lines when using proper EFI rated flared fittings.
Make sure that you remove ALL low pressure flex joints on factory
fuel lines and replace them with EFI rated fuel hose and use proper
flared connections and clamps. Be careful not to mix 45° and 37°
AN fittings , they look similar but will not work together. 45° fittings
usually come from a hardware store or auto parts store while 37°
AN fittings are the ones supplied by Fitech and most speed shops.
Remember that your system will be running at 58 PSI so consult a
rofessional if you are not certain about this portion of your instal-
p
lation. Fitech does not recommend aluminum fuel lines EVER! Or
ou can use the supplied EFI high pressure fuel hose that is supplied
y
in your Fuel Delivery Kit.
• Use the supplied push lock style hose ends only with the supplied
hose and vice versa. Intechanging hose ends and hose with other
rands could cause leaks.

VERY IMPORTANT NOTE: Your fuel tank must have a vent to prevent
pressure building up inside the tank.

Oxygen Sensor Installation
The supplied O2Sensor can be installed in either exhaust
bank. The Sensor cable connects to one of the cables
coming out of the ECU on the throttle body.
A. The ideal location for the Sensor is 2-4 inches after the
exhaust collector. It must always be at least 18-inches
from the exhaust tip. Where short or open headers are
utilized, install the sensor in the primary tube of the rear

cylinder. Must be at least 8-inches from the exhaust port.
It will not work on "zoomie" style headers.
B.The sensor should be at least 10° above horizontal (see
figure #3) to allow condensation to run off. If this is not
adhered to, the sensor is susceptible to water damage.
C. Never position the sensor on the outside of a bend in
the tubing.
