to Nitromethane, Nitropropane and even fuels that contain MTBE and ETBE. Silver plated terminals ensure the best electrical connection possible
along with an EV1 style connector for positive locking and vibration resistance.
Warranty terms
The use of this equipment must be in complete compliance within the terms set out in this manual, failure to do so excludes the manufacturer from
all responsibility.
This product is not certied for aeronautic purposes or any ying vehicles, as it has not been designed for such applications.
Before starting any electrical installation, disconnect the battery.
This product is not certied for aeronautic purposes or any ying vehicles, as it has not been designed for such applications.
In some countries where an annual inspection of vehicles is enforced, no modication in the OEM ECU is permitted. Be informed about local laws and
regulations prior to the product installation.
Important warning for proper installation of this product:
Always remove and insulate unused wires. NEVER roll up excess wiring as this may create an antenna that
captures electromagnetic interference that may generate product malfunction.

Installation
Electrical
- Pin 1: 12V to 24V switched power (never wire to constant power, this will damage the injector)
- Pin 2: ECU injector output (Blue outputs)
Electrical with Peak and Hold
Use the Peak and Hold is mandatory when to use injectors in gray and yellow outputs. In this case its necessary
to install a Peak and Hold 8A/2A. See Peak and Hold manual’s for more information.
Testing your injectors before rst startup
- Go to the outputs screen under the sensors and calibration menu in FTManager software
- Setup each injector output, write map to ECU
- Once the outputs are set, you can power the ECU up and click on the lightning bolt button near each injector output. The injectors will pulse when
the test button is pressed. Test each injector to ensure correct functionality, and to make sure they’re on the correct cylinder and rail according
to your selection.

EN
If your injectors are not working use the diagnostic
guide below
- Check all fuses related to injector power
- Check to make sure all relays related to injectors are energized
- Check for power at the injector connector with a voltmeter or
LED test light
- Check the injector output from your ECU with a noid light set or
LED test light
- Make sure either your peak and hold driver or jumper is plugged
in if using a FuelTech terminated harness
- Check for power and ground at your peak and hold module
Fuel injector installation
O-ring style injectors
a. Lube the upper and lower o ring with petroleum jelly or ATF
b. Press the bottom of the injector into your intake manifold injector
bung
c. Align all injectors and press the fuel rail onto the top of the injector
ensuring all of the o rings are intact and seated properly
IMPORTANT
Once installed, pressurize the system to inspect
for leaks before starting
NOTE
In some cases, it will be necessary to increase the diameter of the injector tting holes in the intake manifold.

Conguration
Navigate to engine settings on the quick access panel.
a. Click Fuel injection
b. Enter your total ow by adding your injectors together
Example: 170lb/h x 4 cylinders = 680
c. Enter your primary injector dead time
Battery voltage compensation
Next step is on battery voltage compensation in fuel tables.

EN
Base fuel pressure (differential)
The recommended base fuel is 43.5PSI, this allows a better fuel atomization in the combustion chamber.
Execute the following steps to regulate it:
a. Disconnect the fuel regulator vacuum hose
b. Rev the engine up to 3000RPM steady
c. Regulate the base fuel pressure at 43.5PSI or desired pressure, making sure to have a stable number
IMPORTANT
It’s not recommended use more than 120PSI of differential fuel pressure, this will damage the injectors

Max ow vs Pressure
Injectors are a volume ow device, This means it ows a certain volume of uid through it at whatever differential pressure you currently have over a
certain amount of time.
Example: cc/min (Cubic Centimeters per minute) or GPM (gallons per minute)
However Injectors are often talked about and displayed in pounds per hour. In Order to accurately dene this you need to know the density of the uid
you intend on owing through them. Below is some simple math on how this is done.
First you must know the specic gravity of the uid you will be owing through your injector. And then you need to know how many grams are in 1
pound (453.592)
Example: 0.72 grams per cubic centimeter or 720 kilograms per cubic meter.
Now you multiply your cc/min ow rate by the specic gravity then divide it by how many grams are in one pound and multiply by 60 to convert from
minutes to hours. Here is how that would calculate out below: (1785cc/min × 0.72 ÷ 453.592) × 60 = 170.003 Pounds Per Hour
If you change to a uid with a different density you need to do the calculation with the specic gravity of that new uid.
Now that we know how it’s calculated, here are some of the more popular fuels used in the racing industry.

Off season maintenance (Removing injectors)
If you will have the car sitting for more than 3 weeks without running, follow the instructions below:
a. Drain or seal your fuel system
b. Remove the injectors from the car
c. Pulse each injector continuously for 3 seconds, applying clean/dry compressed air (30 to 90 psi) into the fuel inlet portion of the injector. This
operation removes residual fuel from inside the injectors.
d. Store your injectors in a plastic sealable bag
If you do not use an oxygenated fuel simply seal your fuel system off by capping the breather and keep the fuel cell or tank lled to the top.
Do not attempt to disassemble the product or to remove or replace any of its components. Any attempt to do so could damage the product and will
void the product warranty. FuelTech will not service or replace any injector that has been opened or where attempts to open are visible. Failure to heed
any of the warnings or precautions described in this manual may cause engine damage and will void this product warranty.
Off season maintenance (without removing injectors)
If you will have the car sitting for more than 3 weeks without running, follow the instructions below:
a. Remove and drain the fuel rail
b. Turn on the ignition and go to the Outputs menu in the FTManager software, hold the “lightning bolt” test output feature button continuously for
3 seconds whilst applying clean/dry compressed air (30 to 90 psi) into the fuel inlet portion of the injector. This operation removes residual fuel
from inside the injectors.
c. Assemble the fuel rail. This procedure is necessary if the vehicle will be sitting for more than 3 weeks without running.
This procedure is necessary of the vehicle sitting for more than 3 weeks without running.

Do not disassemble the product or remove/replace any components. Doing so may damage the product and
will void the warranty.

multímetro ou luz de teste;
- Verique a saída de injeção da ECU com luz de teste
- Verique os relés e fusíveis relacionados aos injetores
Instalação do FT Injector
Injetores tipo O-ring
a. Lubrique o anel de vedação superior e inferior com vaselina
ou ATF
b. Pressione a parte inferior do injetor no coletor de admissão
c. Alinhe todos os injetores e pressione a auta de combustível
na parte superior do injetor garantindo que todos os anéis de
vedação estejam intactos e encaixados corretamente
IMPORTANTE
Uma vez instalado, pressurize o sistema para
inspecionar se há vazamentos antes de iniciar
NOTA
Em alguns casos será necessário aumentar o diâmetro dos furos de encaixe dos injectores no coletor de admissão.
