The dashboard is made in the housing of the standard dashboard. It is compatible with all GD series bodies in terms of dimensions, mountings and connectors.
For connection the OEM electrical connectors of the native braid (3 pcs) are used, as well as additional USB connectors for connection of the joystick dashboard control, GPS antenna, COM-USB adapter (for VEMS ECU). Connection to the OEM ECU is made via K-LINE to the diagnostic connector, or directly to the K-LINE wire through a toggle switch, to ensure the ability to operate diagnostic equipment using the same line.
The USB connectors are interchangeable, the order of connection does not matter. The rear panel has an RJ45 (ethernet) connector for connecting an analog signal converter and CAN bus, which is used to receive data from CAN bus compatible ECUs (LINK, ECUMASTER, STEALTHPCM, MAXXECU, MEGASQUIRT3, SPTRONIC, ABIT).
When using a standard ECU CAN bus can be used to connect an additional module for processing data from analog sensors:
- coolant temperature
- oil temperature
- AT temperature
- engine oil pressure
- fuel pressure
- boost pressure
- exhaust gas temperature
The following types of sensors can be used as additional temperature sensors (calibrations are already stored in the dashboard):
- depo s3747-jpn
- AEM
- defi (original)
- bosch 2in1
Any 5 volt three-wire sensors (aem, bosch, depo, defi, etc.) can be used as pressure sensors. The measuring range can be changed in the settings.
Displayed parameters when using the standard ECU and without the use of additional modules:
- speed
- RPM
- fuel level in liters
- Coolant temperature (standard sensor with an error of up to 5 degrees)
- turn signals
- lamp of emergency oil pressure
- brake handbrake / low brake fluid level lamp
- lamp indication of brake light bulb malfunction
-abs light - charge lamp
- open door lamp
- check engine lamp
- lamp indicator lamp for parking lights on
- high beam indicator lamp
- airbag indicator lamp
- odometer
The dashboard is switched on when the ignition is switched on or when the door is opened. After the ignition is turned off, the dashboard remains on for the configured time interval, then enters the sleep mode with the display off, from which it can wake up instantly when the ignition is turned on. If there is no ignition signal after the set sleep time, the dashboard switches off completely.
The dashboard is controlled by means of a joystick. Enter the menu by pressing the joystick. The brightness is adjusted by turning the joystick knob.

Alerts and Warning Log.
Tachometer
Yellow and red revolutions zone are set, these zones determine the behavior of some arrow tachometers and are also used as shifter lamp trigger zones.
Speedometer
Set the speed threshold after which the speed reading digits change color from white to red, for example, if the speed limit in the city is 80 kmh, you can set the threshold to 78-79.
Coolant temperature
The threshold is set, when it is exceeded, a pop-up window with the current temperature value and a sound signal is displayed. Each alarm is recorded in the warrnings log (time and value).
Oil temperature
A threshold is set, above which a pop-up window with the current temperature value and an audible alarm is displayed. Each alarm is recorded in the warrnings log (time and value).
Engine oil pressure
5 oil pressure values are set for different engine speeds. When the oil pressure drops below the threshold corresponding to the current RPM, a pop-up window and an audible alarm are displayed. Each alarm is recorded in the warrnings log (time, engine speed, oil pressure value).
Exhaust gas temperature
A threshold is set, above which a pop-up window with the current temperature value and an audible alarm is displayed. Each alarm is logged in the warrnings log (time, temperature, rpm, boost, ignition angle, mixture).
Voltage
The lower voltage threshold is set when the engine is running. If the voltage drops below the threshold, a pop-up window is displayed.
Fuel level
The lower threshold of the fuel level is set. A pop-up window is displayed if it falls below the threshold.
Current mixture, desired mixture
Sets the maximum deviation of the current mixture from the desired mixture. Only works with boost values greater than 0.1 bar. Operates only if the ECU is transmitting current and target mixture data. Each actuation is logged in the warrnings log (time, rpm, boost, ignition angle, current mixture, desired mixture).
Ignition angle rollback
The maximum value of the ignition angle rollback is set. If exceeded, a pop-up window and an audible alarm is displayed. Each actuation is logged in the warrnings log (time, rpm, boost, ignition angle, rollback, current mixture).
Logger
Recording of the main engine operation parameters is carried out in automatic mode. The start of recording is determined by simultaneous exceeding of engine speed and pressure in the intake manifold above the specified limits. The limits are set in the LOG-SETTINGS menu. Recording stops if one of these two parameters falls below the set limit.
The log is displayed as a graph of up to 4 parameters at a time, there are several parameter layouts, switching is done by double-clicking up. Navigation left-right by rotating the joystick knob, zooming by pressing left-right. The upper line shows all recorded parameters in text form. When the marker of the current position is moved, the values corresponding to this marker position are displayed in the upper line.
When the ignition is turned off, the record (all saved data from the moment the dashboard is turned on) is saved to the built-in media in the ARCHIVE section. The last 10 records are stored in the archive. If GPS receiver is available, the date, time and length of the record in seconds are added to the record name.
The archive of recordings can be copied to a USB flash card as CSV files for viewing in megalogviewer or analog.
Peak values
Peak values are determined for the main parameters, which are reset either by pressing the joystick up in the peaks window or by turning off the instrument panel.
If data on the current transmission gear and intake manifold pressure are available, the peak pressure values are plotted in RPM-pressure coordinates for each gear.
If cylinder-by-cylinder detonation level data is available, peaks are plotted for each cylinder.
In the presence of data on the current mixture and inlet manifold pressure, a statistical graph is continuously plotted in pressure-rpm coordinates, where the points corresponding to the value of the current mixture for the current rpm and inlet manifold pressure are marked in color.
If there is data on detonation level, a statistical graph is continuously plotted in pressure-rpm coordinates, where the points corresponding to the value of the current detonation level for current rpm and pressure in the intake manifold are marked by the color value.
Acceleration measurements
In the presence of a speed signal, acceleration measurements are made 0-100, 100-200 in automatic mode. The results are displayed on the main screen, in the right panel in the indicator “acceleration”. The indicator is made in the form of a table in which the time of the event, the name of the event, the result of measurement are recorded line by line. For example “00h-35m acceleration 0-100 5.6sec”.
Drift map
If you have a GPS receiver, you can display the driving trajectory in the form of a line with color segments. Each color of the line corresponds to a certain speed of movement. Also in automatic mode the staging speed is measured and the results are displayed in the form of a table. The staging speed is defined as the peak speed before the beginning of braking.
Measurement of lap time.
If GPS receiver is available, it is possible to measure the lap time. For this purpose it is necessary to first determine the start-finish line, then at repeated crossing of this line in any direction the time between crossings will be measured. To set the start line it is necessary to put the car not less than 10 meters from the start line and move perpendicular to it. Then stay on the start line and press the joystick up. The current position will be defined as the start line, located perpendicular to the direction of the car and 5 meters wide on both sides of the car. The line will be displayed on the screen as a thin red line. The measurement results are displayed in the form of a table. The measurement results and the start line are not saved after the power is turned off.
CAN bus monitor
The dashboard can operate in the mode of displaying CAN packets in byte form. The mode is useful for debugging and customizing the operation
