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).

Analo Inputs
Digital ECU Tuner has 4 analog inputs. All operate the oltage from 0 – 5V with 10 bit resolution. Voltages abo e
5V are interpreted as 5V, howe er, such high oltages should be a oided because they may damage the de ice in
bad conditions.
Caution!
All unused analo inputs should be connected to the round!
E ery analog input can be assigned as a modified signal, load or corrections. These assignments can ary
depending on the table, and also the analog signals can be used for different functions (for example as a modified
signal and load).
The output alue of the modified analog signal for fuel table is calculated on the following basis:
Vout = (TableValue * Vstep + Vin + analogOutOffset) * correction1 * correction2
If Vout < Analog Out Min then Vout = Analog Out Min;
If Vout > Analog Out Max then Vout = Analog Out Max,
where,
Vout Output oltage (Analog Out 1)
Vin Input oltage (Analog In 1)
Vstep Modification step ( 0.019V, 0.098V, 0.0049V menu Analog Output Configuration)
TableValue Fuel table alue
Analo OutOffset Analog output offset (menu Analog Output Configuration)
Correction1 Proportional alue from the first correctional table’s cell
Correction2 Proportional alue from the second correctional table’s cell
Load
Load is used to determine the table’s column, where the alue will be used (X axis). The example of the sensor,
which oltage (or frequency) can be used as load, are, for example: TPS (for NA engines only!) , MAP sensor,
MAF sensor, etc.
To obtain as many signal modifications as possible, the range of the input signal must be correctly configured
(Analog Inputs Configuration menu).The minimal and maximal alue of the chosen analog input should be set for
the correct highest and lowest frequency alue indicated by the sensor.
For example, if the MAP sensor gi es 0.5 V at the 40kpa of absolute and 4.0 V at 200kpa, then parameters should
be set: 0.5V and 4.0V, respecti ely. This way, it will be possible to use all cells from the table. It is important,
howe er, not to use the signal from the TPS as load in the turbocharged cars, because the opening angle of the
throttle doesn't reflect the real load of such engine! In this case, signal from MAP or MAF sensor must be used.
Page 15

DIGITAL ECU TUNER 3 – User Manual
Caution !
In turbochar ed cars, a si nal from the TPS sensor cannot be used as Load, because the value
from TPS sensor does not reflect the real load of such en ine! In this case, si nal from MAP or
MAF sensor must be used.
The ranges of the input analog signals can be defined in the
Setup/Analog Inputs Configuration window. In this window,
it is also possible to precisely define the range of the input
oltages and to switch the filtering of the signal using digital
low - pass filter. This option can be ery useful if the input
signal is noisy.
Each analog input can be configured as a correction input.
(eg. ignition angle in function of the temperature intake).
Also, all spare analog inputs can be used for logging
additional signals, like signals from WBO controller.

Analo output (Analo Out)
Analog output (Analo Out) is made of a high quality 10 – bit
DAC con erter. Maximal signal resolution is 0,0049V. In the
Setup/Analog Output Configuration window, it is possible to choose
the oltage step, which would correspond to the alue 1 on the map.
It is 0.0195V, 0.0098V or 0.0049V, respecti ely. The choice of the
step directly influences the maximal possible change of the output
signal. For 0.0195V it is +/- 2.5V, for 0.0098V +/-1.25V and for
0.0049 +/-0.625V. No matter which step of the signal change is
chosen, the interpolation of the map’s alues is conducted with the
full 10 bit resolution. There is also an option to define the initial range of the output signal. It means that
independently of the calculated analog output alue, the output will ne er be lower than Analog Out Min or higher
than Analog Out Max. In the Setup bookmark, it is possible to set the offset (Analog Out Offset) for the analog
output (the way of calculating the alue of the output oltage can be found at the description of the analog inputs).
The possibility to set the alue of the de ice’s initial oltage is an additional option. DET3 needs about 7ms for the
initialization and to start working. During this process, oltage of the analog output equals 0V. It is possible to
enforce a gi en initial oltage during the initialization process. It may be required for some ECU, which at this time
is reading the oltage from a sensor (MAP sensor, MAF sensor), and in case of 0V, to report an error. In such
situations, the initial oltage alue should be set to the sensor’s reading when the engine is turned off.
Attention !
Connectin the analo output directly into the round or + 12V may cause a dama e
of the DAC converter!

The de ice has an ad anced ignition input (Ignition #1 In), with configurable functionality. Thanks to that option,
one input can ser e both signals: the VR and Hall’s/ optical sensors.
Input mode of I nition #1 In Description
VR Sensor adapti e threshold Input mode, which ser es VR sensors. Thanks to the signal true zero cross
detection and the adapti e hysteresis, this input mode is ery noise immune.
VR Sensor fixed threshold This mode is used to ser e VR sensors using true zero cross detection and

be higher than 2.5V.
Other sensors This mode ser es other inducti e and Hall’s sensors without hysteresis.
The de ice has 3 ignition outputs:
1) I nition Out (Pin 6) – used for the unipolar signals,
2) Bipolar I nition Out (Pin 5) - used for the bipolar, unbalanced signals (single ended),
3) Bipolar I nition Out Inverted (Pin 4) – complementary signal for the signal from the output Bipolar
Ignition Out used for bipolar, balanced signals (differential),

Value of the ad ance angle change is calculated as follows:
I nAn le = MapValue + CorrMap1Value + CorrMap2Value
If I nAn le < Maximum Retard then I nAn le = Maximum Retard
If I nAn le > Maximum Advace then I nAn le = Maximum Advace
Positi e alues on the table correspond to the ad ancement of the mixture ignition, negati e alues retarding the
mixture ignition. Depending on a type of a modified signal, which controls the ignition, the range of the ad ance
angle changes. Therefore, the permitted change for a signal from the toothed wheel is 60-2, +/- 90 degrees.
In case of retarding of the symmetrical signal from the camshaft or crankshaft sensor, a permitted angle equals to
the angle between two consecuti e teeth. Therefore, if there is a toothed wheel with four symmetrical teeth on the
crankshaft, the angle between the teeth is 90 degrees and it is the maximal angle of the ignition retard. Ignition
configuration can be done in the Setup/Ignition Configuration menu.

Si nals types
Depending on the kind of crankshaft / camshaft sensor, there are different kinds of signals sent from the sensors.
The simplest sensor is the ariable reluctant sensor (VR sensor), which, based on the induction laws, generates
bipolar signal, which amplitude depends on the rotational speed of the crankshaft / camshaft. The signal has
approximately the shape of a sinusoid. With low engine rotation speed, the oltage amplitude is measured in
dozens mV and may reach a few dozen Volt with its high re olutions. Some of the car ECU interprets a signal for
the sensor as single ended, which means that one of the sensor’s poles is connected to the ground and the signal is
taken from the other one. The second approach is treating the signal form the sensor as a balanced one
(differential) and using both hal es of the signal.
Another kind of sensors are optical/ Hall’s sensors. They require power supply and generate a rectangular, unipolar
signal.
Unipolar signal. Bipolar si nal
Information about the type of a signal is crucial for the correct
configuration of the de ice. For VR sensors, in Setup/Ignition
Configuration menu, choose the Input Type: VR Sensor a aptive
Threshol Ignition . For optical/ Hall’s sensors choose Hall Effect or
optical sensor. Choosing an incorrect type of signal may cause an
incorrect functioning of the de ice (lack of engine speed, ignition
errors, etc.)
