DIGITAL ECU TUNER 3 – User Manual
Attention!
Digital ECU Tuner 3 can be used only for motor sports and cannot be used on public
roads!
The installation of the de ice can be conducted only by trained specialists. The
installation performed by an unskilled person may lead to the damage of both the de ice
and the engine!
Incorrect tuning of the engine with Digital ECU Tuner 3 (DET3) can result in a serious
damage of your ehicle!
Ne er modify the de ice’s settings when the car is mo ing because it may cause an
accident!
Ecumaster is not responsible for the damages caused by an incorrect installation or/ and
tuning of the de ice!
Important !
The manual below refers to the 1.0 (HW Version 1.0) ersion of the Digital ECU Tuner 3
(DET3).
Modification of the tables should be conducted only by people who understand the
working rules of the de ice and working rules of the modern injection and ignition
systems.
Always use the AFR meter during the modification of fuel settings.
Ne er short-circuit the lines of the engine’s wiring loom as well as the outputs of the
DET3 de ice.
All modifications of the engine’s wiring loom as well as of the DET3 de ice must be
performed with the unplugged negati e terminal of the battery.
It is important for the quality of the joints of the wiring loom links to be high and to be
correctly insulated.
The connection wires should not be longer than 30 cm.
All signals from the ariable reluctant sensors should be connected by using shielded
cables.
E ery unused input should be connected to the Ground.
The de ice must be disconnected during welding of any car body elements,!

Di ital ECU Tuner 3
Description of the device
Digital ECU Tuner 3 is used to modify signals from sensors to ECU (Electronic Control Unit). Thanks to this
function, it is possible to modify such engine parameters as the fuel dose, ignition angle, boost controlling or extra
injectors. Additionally, some of the de ice’s functions help to tune the car thanks to the ad anced datalogger and
the road dyno, which can measure the power and the ehicle’s torque in the real conditions (a car dri ing on the
road).
The device’s characteristics
•4 independent tables 16x 16 (fuel table, two PWM tables, ignition table),
•8 correction tables 16 x 1,
•2 independently switching table sets,
•an option to modify a single analog signal,
•4 analog inputs,
•built in Data Flash, which enables the signals to log in without plugging in the laptop,
•measurement of the power supply oltage,
•an option to modify a signal from the frequency based MAP and MAF sensors (in range of 17Hz-4kHz),
•supporting the ignition signal with using: ariable reluctant sensors, Hall’s, optical sensors and signals,
which control the ignition module. The de ice ser ices both the single ended and differential signals.
•support of many ignition types: 60-2, 36-2, 36-1, 18-1-18-1, EDIS, Multitooth, Ignition Modules, Subaru
GT, Honda D Series,
•an option of boost control using 3 way solenoid al es,
•ser icing of 4 high-Z injectors (batch fire system),
•an option for a direct modification of the injection time for the batch fire systems,
•ON/ OFF type parametric output,
•automatic con ersion from MAP to MAF using auto learning system,
•launch control,
•road dyno,
•an option to calibrate any analog sensors, which enables the analog alues to be displayed in their real
alues ( for example, a signal from MAP sensor in bars, a signal from a WBO meter as AFR, etc.) ,
•an option for a free firmware upgrade ( new ignition modes, additional functions),
•USB communication port.

Minimal PC confi uration
For the correct functioning of the de ice, the following minimal configuration is required:
•Windows 2000, XP, Vista , Windows 7
•128/256/512 MB RAM
•Resolution, at least 1024x768 16bit,
•600MHz CPU or better,
•USB
Elements of the set:
•DET 3 de ice,
•USB AA cable,
•Connector,
•A set of connector pins,
•CD with the software, dri ers and the user’s manual in English,
•Additional set of resistors and a rectifying diode, useful for the installation of the de ice.
Firmware
Firmware is the internal software of the de ice which is responsible for its functioning. Because Firmware is
upgradeable, it is possible to update it, which will make the de ice more functional in the future. Additionally, to
use a new firmware, a proper software (client) should be used for Windows. The software is compatible
‘backwards’, which means that the new ersion of the software for Windows works with all pre ious ersions of
the de ice’s firmware. The latest software can be found at www.ecumaster.com .

Firmware's update
Due to the changes in the de ice’s firmware, (for example:
impro ements, additional functions) it is possible to change the
firmware.
To do this, the Upgrade firmware... function should be used (in
the File menu). To choose a new firmware, press Open. In the
Firmware History window there will be displayed a list of
conducted changes for a gi en firmware. To continue, press the
Upgrade button.
A window with a warning will be displayed: “All your tables and configuration will be lost.”
After accepting, a window informing about the progress of
the firmware’s change will be displayed. At this time, don’t
switch off the computer nor the de ice! If, during the
installation, communication with the de ice will be broken, to rescue the installation do the following:
1) Connect the de ice to a laptop,
2) Power up the de ice,
3) Start the client for Windows,
4) Choose Upgrade Firmware from the menu and follow the abo e directions.
Attention!
Updatin the firmware causes the loss of the saved tables and setup parameters! The
project should be saved on a disc before updatin !
Warnin !
Firmware chan e should not be conducted if there are problems with the
communication between the device and PC computer!!!

Software installation
Client installation
To install a client, executable file (EcumasterDET3_1_xx.exe) should be acti ated. After choosing a language and
accepting the license agreement, choose the targeted folder. It is important to remember that before installing a new
ersion, the old one should be uninstalled! User’s folders will be sa ed.
Driver’s installation
Windows XP
During the first connection of the de ice to a computer, a message will appear, informing that a new equipment is
found.
Next, choose the option: “Install from a list or specific location”. When installing from a CD from the set, choose
CD and DET3\USB_DRIVER folder, (for example, D:\DET_3\USB_DRIVER). If the dri er is installed from a
hard dri e (for example downloaded from www.ecumaster.com) choose a proper folder.
The abo e directions should be repeated for e ery new equipment found by the computer. If FTDI dri ers of FTDI
brand are already installed on a computer, the information about finding a new equipment will not appear and the
dri ers’ installation will not be necessary. After a successful installation, a client can be started.

Tables
Digital Ecu Tuner 3, has 4 3D, 16x 16 tables which allow to modify / generate signals in the engine’s speed and
load functions. Additionally, e ery 3D table has two 2D correction tables assigned (16x1).
Interface description
1) Table’s area is 16x16. Values in the table’s cells ha e different meanings for each map (and sometimes mode):
- for the Fuel Table, the alues mean a change of a defined input signal (Analog In), or a change of the
frequency of the signal from the input Ignition#2 In (more on the topic can be found in the chapter about
frequency signals’ modification.).
- for the PWM1/PWM2 tables, alues in the cells denote the le el of impulse duty cycle (0 – 100%). In
the mode of the direct injectors steering, table alues range from 0 – 200%.
- for the Ignition table, alues in the cells denote the angle of the ignition retard (negati e alues), or
ignition ad ance (positi e alues).
2) 3D table graphics representation. To rotate the 3D graph, keep the left mouse button pressed and mo e it on the
3D area.
