2. Presentation
Congratulations! You are now part of the high performance world
of FuelTech! Know that this equipment is exactly the same used in
many winners cars around the world. From NHRA drag race cars and
circuit race cars to exotic brands with 12 cylinder, the FT500 SFI and
FT500LITE SFI represent the maximum technology, ease of use and
performance that an ECU can provide. We, from FuelTech, wish you
have many victories and have fun on your path, because winning is
in our DNA!
The FuelTech FT500 SFI/FT500LITE SFI is a fully programmable
ECU, which allows you to change all fuel and timing tables, as the
engine conditions, in real time. You can tune your engine directly
on the ECU, through its screen touchscreen 4.3’’ (only FT500 SFI)
or via FTManager software (FT500 SFI and FT500LITE SFI) with
high-speed USB communication. The tuning of main fuel and timing
tables may be performed in basic (2D) or advanced (3D) mode with
configurable break points. It can be applied to any type of engine Otto
cycle using indirect injection, 2 or 4 strokes, up to 12 cylinders or
4 rotors, gasoline, ethanol, methanol, CNG, nitromethane and other
compatible fuels.
The electronic throttle control is fully integrated to the module and
configured directly in the display without any additional computer or
module. It is possible to set alerts to dangerous situations for the
engine, such as over rev, low oil pressure, high engine temperature,
among others. These alerts can also be programmed to limit rpm or
shut off the engine bringing more security the user. The ECU also
features five maps fully independent, allowing different settings to
engines and/or cars.
The timing control can be done through distributor or crank trigger.
Thus, it is possible to work with a single coil, double coils or COP coils,
on wasted spark or sequential ignition. The fuel injectors can work on
sequential, semi-sequential or multipoint mode, with individual cylinder
trim. Tune the injection phase angle is also possible.
The equipment also has the Favorites menu, which seeks to facilitate
access to the main engine setup menus, allowing executing rapid
changes in maps. The dashboard panel is fully configurable, where
the user can change the display size and the types of readings for
each parameter, as well as reading range presented on the screen.
The FT500LITE SFI is a FT500 SFI without touchscreen. If you want
to upgrade your FT500LITE SFI to FT500 SFI, please contact our
technical support.

4.4 Auxiliary outputs
As FT500’s outputs can be set up in many different ways, they
have different capacities according to the function. Bellow is
some important information about them:
Blue outputs [#1 to #8]: by standard, used as injector outputs. Each
one of them can control up to:
- 6 saturated injectors impedance above 10 Ohms (maximum of
12 injectors considering all of the blue outputs)
- 4 saturated injectors impedance between 7 and 10 Ohms
(maximum of 8 injectors considering all of the blue outputs)
The use of a Peak and Hold driver is mandatory when the number of
injectors is higher than the maximum quoted above or when using
low impedance injectors (impedance below 7 Ohms).
During the Engine Setup configuration, blue outputs will be selected
automatically from Blue #1 to Blue #8.
When more than 8 injector outputs are needed, the ECU will use Gray
#1 to Gray #8 or Yellow #1 to Yellow #4. In this case, the use of a
Peak and Hold driver is mandatory on Gray and Yellow outputs (for
saturated and low impedance
injectors).
Blue outputs not used to control fuel injectors may be used as auxiliary
outputs (controlling fuel pump, cooling fan, etc.). In this case, the use
of a relay is mandatory.
Gray outputs [#1 to #8]: by standard, used as ignition outputs.
According to the engine setup, they can be set up as injectors or
auxiliary outputs.
During the Engine Setup configuration, ignition outputs will be selected
automatically from Gray #1 to Gray #8. It’s not possible to have more
than 8 ignition outputs.
Gray outputs not used for ignition control can be set up as injectors
outputs (the use of a Peak and Hold driver is mandatory) or as auxiliary
outputs (the use of a relay is mandatory).
Yellow outputs [#1 to #4]: by standard, they’re as electronic throttle
control (Yellow #1 and #2) or stepper motor control (Yellow #1 to #4).
Yellow outputs not used for electronic throttle control can be set up
as injectors outputs (the use of a Peak and Hold driver is mandatory)
or as auxiliary outputs (the use of a relay is mandatory).
Tach output: by default, it is configured in the gray #8, but if this
pin is needed for other function, we recommend to use one of the
yellow outputs for tach. If the yellow wires are being used, you can
use any other output with a 1k ohms pull-up resistor connected from
the signal to 12V.
4.5 Internal MAP sensor
This ECU is equipped with an internal MAP sensor. Use a 6mm
pneumatic hose (4mm internal diameter) to connect the sensor to
the intake manifold. Pneumatic hoses are flexible, durable and highly
resistant. Usually found in black or blue colors.
Silicon hoses are not recommended because they can be easily bent,
blocking vacuum/boost readings on the ECU MAP sensor.
Use a hose exclusively for FT MAP sensor, avoiding splitting it with
valves, gauges, etc. Connect it to any spot between the throttle and the
engine head. Its length must be as short as possible to avoid lags and
errors on the sensor readings. When using individual throttle bodies,
it is a good idea to connect all intake runners into a single point and
then connect to the FT MAP sensor; otherwise, MAP readings may
be erratic or inaccurate.
4.6 USB port
The USB cable is used to update the ECU firmware version, setup
maps and adjusts trough a computer and FTManager software and
download data recorded by the internal datalogger.
4.7 FuelTech CAN network
FuelTech CAN port is a 4 way connector placed on the back of the
ECU and is responsible for FT500 / FT500 LITE communication
with other FT modules (as KnockMeter and GearController) and
Racepak dashboards. A FuelTech CAN-CAN cable is used to establish
a connection between them.

5. First steps with FT500 / FT500LITE read
before installation
This chapter is a step-by-step guide that must be followed to start
FT500 / FT500LITE basic setup before electric installation, as the
function of each wire may vary according to engine setup (number of
cylinders, injectors control mode, ignition coils and auxiliary outputs).
1. Connect the flash drive in the PC USB port and install the
FTManager software. Remember to check if the software and
the ECU are in the lastest version at www.fueltech.net.
2. Connect FT500 / FT500LITE to the computer using the USB
cable included on the package. The ECU will be powered up;
3. With the ECU in hands go through chapter 6, that introduces all
basic information about menu navigation and operation;
4. Chapter 7 guides the user through all the menus where data

and ignition control modes, etc.);
6. Getting to know the ECU
6.1 Main menu
Navigation through touchscreen is intuitive, because the ECU display
makes the access to information very easy, eliminating physical
buttons. So, all changes on maps, setups and functions are done by
light touches on the screen.
To enter menus, press the screen twice, just like a double click. This is
a feature that prevents the user from entering the wrong menu when
managing the ECU inside the car.
1 - Dashboard: Shows real time engine information (RPM,
Temperature, pressure, timing, injection time, etc.)
2 - Fuel Tables Adjust: Main fuel map, overall fuel trim, RPM
compensation, TPS idle fuel table accel fuel enrich and
decay, engine and intake temp, compensation battery voltage,
compensation, post start enrich, ect.
3 - Ignition Tables Adjust: Main ignition map, overall ignition
trim, MAP / TPS compensation, air and engine temperature
compensations , individual cylinder trim, timing split, etc.
4 - Alert Settings: Access to shift alert settings, safe mode RPM
limiter, alerts by fuel and oil pressure, TPS, etc.
5 - Engine Settings: Engine basics info as inition mode, RPM signal,
pedal/throttle settings, idle actuador, injectors deadtime, ignition
dwell, wiring harness diagram.
6 - Interface Settings: LCD backlight and alert sounds, dashboard
configs, meansurement units, touchscreen calibration serial
number and version.
5. The last step before the electric installation is to check harness
connections. Go to the “Engine Setting” menu then click the last
option “Wiring harness diagram”. Check and write down the
connections and use it as guide to know how functions were
allocated to the pins. TIP: take photos with a mobile phone.
6. Chapters 8 to 14 guide through details related to the electrical
installation of injectors, coils, 12V inputs, grounds, sensors,
etc. Chapter 25 shows full wiring diagrams as example for your
installation;
7. Chapter 15 gathers information on sensors settings for
temperature, pressure, RPM, speed, etc.
8. With the electric installation finished, proceed to chapter 15.14
and check all the information needed for the first start of the
engine, ignition calibration, sensors checking, etc.
9. Lastly, chapters 17 to 24 show detailed descriptions about all
functions of the ECU. It is a very interesting reading; it also details
every function and operation that the FT can perform.

6.3 Warning sounds in FT500LITE
The FT500LITE has several warning sounds that indicate error
conditions, safety alerts or gear shifting rpm. Check out the meaning
of these alerts:
Short duration alert at short intervals (40 ms with sound,
10 ms without sound)
• Shift alert: the alert turns on at a programmed rpm.
Average duration alert at short intervals (400 ms with
sound, 100 ms without sound)
This warning refers to any safety configuration inserted in the Alerts
Settings menu
It can refer to:
• Over rev
• Injector duty cycle
• Overboost
• High oil pressure
• Low oil pressure
• Minimum oil pressure @ RPM
• High engine temperature
• Low fuel pressure
• Base fuel pressure
The alert will only sound if the function is enabled at the Alert Settings
menu.

FT500 SFI / FT500LITE SFI
15
Long duration alert with average intervals (800 ms with
sound, 400 ms without sound)
This alert may correspond to different situations in ECU:
ECU firmware error: (need to update the module via the FTUpdater);
Missing cam sync sensor: a setting was sent to the module which
requires the use of cam sync sensor (12 teeth crank trigger and
sequential ignition). In this case, go to the RPM Signal menu and
enable the cam sync sensor;
Ignition must be configured as a distributor: a configuration has
been sent to the module that only works in distributor mode. In this
case, connect the module to the PC and go to Ignition menu and select
the “Distributor” option;
Disabled outputs: connect the FT500LITE to the PC, go to the Engine
Setup menu and select the check box “Enable Outputs pins”;
TPS not calibrated: connect the module in USB and calibrate the
TPS before starting the engine;
These alerts will be played continuously and will only stop when the
error condition ceases to exist.
IMPORTANT:
When connecting FT500LITE to the USB, it is
normal that the warning sound is weak. It is a
strategy to save the battery when connecting the
ECU to notebooks.
6.4 Dashboard screen
When the engine is running, the dashboard screen shows real-time
information of sensors that are being read by the ECU.
Chapter 23.3 has more information on how to change the instruments

The Diagnostic Panel is a tool used to detect anomalies on FT500
inputs, outputs, sensors and actuators. In order to access it, touch its
icon , at the main menu.
Information is split on 6 pages:
• Page 1: general engine information;
• Page 2: status of white inputs;
• Page 3: status of blue outputs;
• Page 4: status of gray outputs;
• Page 5: status of yellow outputs;
• Page 6: RPM reading diagnostics;
Pages 2 to 5 shows input/output at the left column, position/command
sent to the actuator, (outputs)/voltage read (inputs) at the central
column and the main information used to calculate the position/
command at the right column. For a thermatic fan output, i.e., diagnostic
panel shows its status at the center column and the engine coolant
temperature at the right column.

Getting to know the ECU
On page 6 are information regarding the engine RPM signal readings.
Below are some common erros and possible causes:
Crank trigger error: gap detected at the wrong spot - it detected
the gap (missing teeth) in the wrong place; it can also happen with a
trigger wheel without missing tooth when there is a cam sync signal
in the wrong place. Also occurs in engines with a very light flywheel
that accelerates and decelerates quickly during compression strokes
at engine startup and running.
Crank trigger error: wrong number of teeth - number of teeth is
different on the crank trigger wheel than what is set at ECU. Electrical
noise can cause a reading of a “ghost” tooth, for example.
Crank trigger error: missed tooth reading - the ECU detected less
teeth then it should have. Also happens in engines with a very light
flywheel that accelerate and decelerate very fast during compression
strokes at engine startup and running.
Crank trigger error: abnormal acceleration - tooth error detection.
Usually caused by signal noise.
Cam sync sensor: signal noise - cam sync signal detected in the
wrong spot. Typically this error is caused when the ECU detects noise
in the cam sync sensor signal or when the cam trigger wheel has
more than one tooth.
ATTENTION
when the 2-step and 3-step are set to activate
by speed, its operation can be checked through
the page 1 of the Diagnostic Panel, not through
page 2, since you are not using an analog input
(white wire) to switch

7. Engine settings
FuelTech ECUs leave the factory without maps or adjustments, so you
need to create the injection maps, ignition and the inputs and outputs
settings before running the engine.
The FuelTech Default is an automatic calculation of the basic injection
and ignition maps for your engine based on the information provided
in the “Engine Settings”. Performing this automatic adjustment every
injection and ignition maps, including temperature compensation, etc.
will be filled based on your engine characteristics.
The information provided must be correct and consistent, maximum
RPM and boost values should be according to the engine capacity and
the injectors should be properly sized to the estimated engine power.
The use of an instrument, such as oxygen sensor (wideband
recommended) and/or an analyzer of exhaust gases, to make the
analysis of the air/fuel mixture is extremely important.
Caution, especially in the start-up, is needed, since it is an initial tune
that will meet most engines, there are no guarantees for any situation.
Be extreme cautious when tuning your engine, never requires high
loads before it a good tune.
Start tuning with a rich map and a conservative timing, because starting
with a lean map and advanced timing can severely damage the engine.
To create a default map by FTManager, click the “File” menu and
then “New” to start the wizard. The menu “Engine Settings” will be
passed in sequence.
Check in later chapters the descriptions of all these options required
to complete the step by step and create the default map.
To generate a new map through the touchscreen, just get in a setting
that is empty and a message appears telling you that the setting is
empty and asking if you want to create a new tune.

TPSMAP
MAP: this mode is indicated for turbo or naturally aspirated engines.
That’s the mode that better represents engine load, because engine
vacuum varies under different loads, even with the trottle on the same
position.
TPS: this option is mostly used on naturally aspirated engines with
aggressive camshafts, when this causes the vacuum on idle and under
low load conditions to be unstable. When this option is selected, MAP
compensation is available for fuel and timing maps.
TPS idle fuel injection table: This is the mode the fuel injection
on idle speed will be controlled. When enabled, a table that relates
injection time versus engine RPM is activated whenever TPS is equal
to 0%. Enable this feature an engines with high profile camshafts and
unstable vacuum on idle.
For street cars with stable vacuum on idle, it is recommended to keep
this feature disabled. In this case, injection time for idle will be set up
directly on the vacuum ranges on the main fuel MAP.

this parameter to Inverted (Rising Edge)
First tooth alignment: set here the crank trigger alignment related to
the TDC. This alignment can be checked by turning the engine to the
cylinder #1 TDC and counting, counterclockwise, angle distance, from
the crank trigger gap to the RPM sensor. If there crank trigger has no
gap, the angle distance is from the previous teeth to the RPM sensor.

according to chapter 16. When the ignition is not
correctly calibrated, the timing shown on the ECU
screen is different from the one that is being applied
to the engine. This may cause serious damage to the
engine.
Cam sync sensor
This option indicates if a cam sync sensor will be used and if it uses a
hall effect or magnetic variable reluctance (VR) sensor. This sensor is

option only for tests, because with individual coils and sequential
ignition the firing order can be lagged (inverted) in 360º, so the
engine won’t start.
Cam sync sensor edge: this option changes the way the ECU reads
the cam sync signal. As there’s no simple way of telling which one is
the correct option (without an oscilloscope), select the option Falling
edge. If the engine starts with misfires, change this parameter to
Rising edge.
Cam sync position angle
The adjustment is degrees before top dead center (ºBTDC) of cylinder
1 combustion.

position angle
Engine position angle (BTDC)
when the cam sync sensor is
over the cam sync teeth. This
information is used to improve
noise rejection and prevent
cam sync errors and doesnt
require precise number since it
doesnt affect timing precision.
This angle is not mandatory and won’t affect the ignition calibration.
If you don’t know the position angle, set the same alignment as crank
index position or select the cam sync sensor as random.
With the random mode enabled, the position angle in the log and
diagnostic panel.
