DIGITAL ECU TUNER 3 – User Manual Analog Inputs Digital ECU Tuner has 4 analog inputs. All operate the voltage from 0 – 5V with 10 bit resolution. Voltages above 5V are interpreted as 5V, however, such high voltages should be avoided because they may damage the device in bad conditions. Caution! All unused analog inputs should be connected to the ground! Every analog input can be assigned as a modified signal, load or corrections.
DIGITAL ECU TUNER 3 – User Manual Caution! In turbocharged cars, a signal from the TPS sensor cannot be used as Load, because the value from TPS sensor does not reflect the real load of such engine! In this case, signal 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.
DIGITAL ECU TUNER 3 – User Manual Analog output (Analog Out) Analog output (Analog Out) is made of a high quality 10 – bit DAC converter. Maximal signal resolution is 0,0049V.

DIGITAL ECU TUNER 3 – User Manual Signals types Depending on the kind of crankshaft / camshaft sensor, there are different kinds of signals sent from the sensors. The simplest sensor is the variable 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.
DIGITAL ECU TUNER 3 – User Manual in case of a VR sensor connected to the ECU as single ended, signals should be connected to the ignition input Ignition In (9), and the signal’s output to Bipolar Ignition Out (4). ECU Ignition In (9) Bipoloar Ign.

DIGITAL ECU TUNER 3 – User Manual Boost control To control the boost pressure of the turbocharger, connect the suitable 3 way electro valve. It should be able to work with a relatively high frequency (>30Hz) and allow the control with duty cycle at least from 20% to 80%.
DIGITAL ECU TUNER 3 – User Manual Controlling additional injectors The device can control up to 4 high-Z injectors per 1 power output. Using PWM map, it is possible to control the opening time of the extra injectors, and as a result, enriching the fuel mixture. A typical connection of the additional injectors is as follows: Power Out #1 (20) Power GND (19) Injectors DET 3 +12V The PWM frequency should be set in range of 30 – 40 Hz.
DIGITAL ECU TUNER 3 – User Manual Direct control opening time of injectors When the injector system works in the “Full group” mode (all injectors work simultaneously), it is possible to directly control the injectors’ opening time. The connections should be as follows: ECU Power Out #1.(20) Injectors Freq.

To do this, click the right mouse button on the map area and choose Display As/ Frequency on the context menu. Page 36 www.ecumaster.
DIGITAL ECU TUNER 3 – User Manual 2. Generating of the frequency signal using the Fuel Table. In the frequency MAF sensor to analog MAP sensor conversion, choose the frequency generating mode. The output frequency is generated based on the fuel table values. Frequency of the generated signal is calculated in the non linear way. For this mode, input signal from the Frequency In input is ignored.
DIGITAL ECU TUNER 3 – User Manual 3. Clamping the upper and lower value of the input frequency. When “clamping” the frequency signal value is necessary (for example, removing road speed governor by limiting frequency of the VSS sensor) it is advised to use “Clamp VSS frequency signal” mode. This mode doesn't require the Fuel Table, so this table can be used for other purposes.

DIGITAL ECU TUNER 3 – User Manual Scales configuration There is an option to connect different kinds of sensors, which represent voltage, pressure, temperature, AFR, etc. to the analog inputs. Basic unit of the input signal measurement is voltage in Volts. However, it is easier to use signals with the value expressed in units, which are measured by the signal (for example pressure in Bars). And for this purpose, scales of the analog inputs can be used.
DIGITAL ECU TUNER 3 – User Manual Signals logging Dataloger is a basic tool used during tuning of a car. It helps to trace the changes of signals, which are being logged and modified, and make decisions about the modifications of the tables. Using extra analog inputs, with the help of the external WBO controller, it is possible to log a current composition of the mixture (AFR).
DIGITAL ECU TUNER 3 – User Manual -Dyno start marker, marking the beginning of the area of the log used for generating the dyno graph, - Dyno end marker, marking the end of the log used for generating the dyno graph, - Make dyno graph, generating the dyno graph. 5) Area marked by using the Dyno start/end marker option, 6) Options of displaying the device’s outputs and inputs on the log. Every signal is logged, even when it’s not marked as a displayed signal.
DIGITAL ECU TUNER 3 – User Manual Road dynamometer It is possible to generate the torque and power graph on the vehicle’s wheels, based on the data from the data log. Additionally, it is possible to put any signal from the analog inputs on a graph. To do this, it is required to drive on a flat fragment of the road, which will allow the car to accelerate on a given gear in the full rotational speed of the engine.
DIGITAL ECU TUNER 3 – User Manual For example, for Opel Astra (Astra Vauxhall) these values are 0.28 and 2.06 m2. For Audi A3 0.31 and 2.13 m2, respectively. There is also an option to correct the graph concerning the car’s rolling resistance. It is important though to have data about the loses on a given gear in the revolutions function (for example, a graph from the roller dynamometer with the loss put on it). Next, these data should be written in the Trans and tires looses table.
DIGITAL ECU TUNER 3 – User Manual The generated graph can be exported to a folder in a BMP format. To do this, choose Export Dyno Graph as BMP option from the Dyno menu. It is also possible to export text data in CSV format for further analyzes in other programs (eg. Microsoft Excel). To do this, choose Export Dyno Graph to CSV file option from the Dyno menu.. Page 45 www.ecumaster.
DIGITAL ECU TUNER 3 – User Manual Launch control Launch control function (starting procedure) is used to set the optimal starting engine speed (for a given RPM the ignition is cut off). In turbocharged engines, it also enables the increase of the boost pressure at the start thanks to retarded ignition and an increased fuel dose. Caution ! Using the launch control function in the turbocharged engines may lead to damaging the turbocharger.
DIGITAL ECU TUNER 3 – User Manual Scope DET 3 device has a possibility to analyze the trigger signal from the Ignition #1 input. To activate this feature, choose the Scope ignition mode from menu (Setup/Ignition configuration), and the Ignition input type suitable to sensor type. In this mode, the signal from the ignition input is copied to the ignition output, what allows to run the engine, but there is no possibility to modify ignition advance nor to store tables using the Make maps permanent function.
DIGITAL ECU TUNER 3 – User Manual MAF (0-5V) to MAP conversion To make the conversion, connect MAF sensor to one of the analog inputs of DET 3.As a load connect map sensor.
DIGITAL ECU TUNER 3 – User Manual Corrections on the map should be made if needed (special attention should be paid to the idle revolution). Additionally, using the air temperature sensor in the intake manifold, it is possible to make correction of the fuel dose, depending on the intake air temperature (lower the fuel dose when the temperature of the intake air rises). Caution ! In some cars, ECU checks the value of the signal from the flow meter just after the car’s start.
DIGITAL ECU TUNER 3 – User Manual Conversion of the frequency MAF into analog MAP sensor To make the conversion, connect the frequency MAF sensor to the Frequency In input and analog MAP sensor to the one of the analog inputs (load). In most cases, signal from frequency MAF will require a pull-up resistor at the Frequency input. In the example below, MAP sensor is connected to the analog input #4.
DIGITAL ECU TUNER 3 – User Manual Corrections on the map should be made if needed (special attention should be paid to idle revolution). Additionally, using the air temperature sensor in the intake manifold, it is possible to make correction of the fuel dose, depending on the intake air temperature (lower the fuel dose when the temperature of the intake air rises).
