The Editing Screen
The editing screen consists of the menu bar and the main screen area which can contain one or more selection, editing and status windows. All the work done through the laptop software takes place in the editing screen, the child windows contained within it and the panels and settings screens that can be opened using the menus and navigation elements.

Menu Bar
The menu bar at the top of the screen provides seven lists of menu items to select from:

Pasted Graphic


The File list allows you to open and save maps from either the Hydra Nemesis 2.7 unit or any of the laptop storage devices. It also allows you to exit the laptop software. It also has the “Import 2.7 Map File” function. Importing a 2.7 map allows specific maps and settings from other files to be imported into the current maps and settings contained in the laptop software. It is also the only method to convert maps and settings from older Hydra Nemesis 2.7 files into the 2.7 system. Pressing Alt+F also brings down the list of items available from the File menu.

The Edit list provides access to editing functions. Pressing Alt+E also brings down the list of items available from the Edit menu.

The Tuning Maps list allows you to select from the various available groups of maps and panels. This is one method of navigating to all of the maps and settings contained in a Hydra Nemesis 2.7 unit or file. The Number of Maps shown will depend on which Experience Level you chose in Tools-experience level. Pressing Alt+M also brings down the list of items available from the Map Group menu.

The Settings list allows you to select from one of the maps in the current Map Group. The content of this list changes depending on the last Map Group selected. Pressing Alt+M also brings down the list of items in the current Map menu.

The Comms list allows you to enable and disable the communications link with the Hydra Nemesis 2.7 unit. As we will later see, some functions can only be performed with communications between the laptop and the unit enabled and others can only be performed with the communications disabled. Pressing Alt+C also brings down the list of items available from the Comms menu.

The Tools list provides access to several useful tools and panels. Pressing Alt+T also brings down the list of items available from the Tools menu.

The View list allows for different default screen layouts to be selected. Pressing Alt+Valso brings down the list of items available from the View menu.

The Help list provides access to information about maps, hotkeys and other useful information. Pressing Alt+H also brings down the list of item available from the Help menu.

Work Area
Each child window can be minimized by clicking on the leftmost of the three square icons on the top-right corner of the window:

Pasted Graphic

When minimized, the window disappears to the bottom-most edge of the main parent window and shows up only as a small tab. The leftmost of the three square icons on the right end of the tab can be clicked again to restore the child window back to the original location it occupied when it was minimized:

Pasted Graphic


Each child window can be maximized by clicking on the middle of the three square icons on the top-right corner of each window or minimized window tab:

Pasted Graphic

When maximized, the child window expands to cover the entire main parent window and the three icons move to the top, right corner of the main screen. The maximized window can be returned back to the original location it occupied when it was maximized by pressing the middle icon again.

Each child window can be dragged to any location on the main screen and even mostly off the main screen by clicking on the top title bar of the window and, while holding down the left mouse button, moving the window to the new location desired:

Pasted Graphic

Each child window can be adjusted to any desired size by clicking any edge of the window as the mouse cursor turns into a vertical, horizontal or diagonal adjustment arrow pair and holding down the left mouse button while moving the edge of the window to adjust the size of the window:

Pasted Graphic

In some of the windows, making the window smaller than the contents of what it is displaying will cause horizontal and vertical scroll bars to appear so that the desired portion of the contents within that window can be moved into the visible portion of the window. To do this, use the left mouse button to click and drag the horizontal or vertical scroll handles to bring the desired content into view:

Tuning Maps
Tuning maps are located in the menu bar at the top. Clicking on any of the maps under the Tuning Maps menu will open the maps’ layout in the program. The maps included are shown below. More information on this menu is available in this manual under “The Maps Menu.”

Pasted Graphic 1

Note that some maps are hidden depending on your Experience Level. To view all maps for tuning, make sure your Experience Level is set to “Guru”. To do this, select “Guru” under Tools →Experience Level. If you are a beginning tuner, you may want to choose “Novice” instead.

Settings
Settings are located under “Settings” in the top menu bar. All settings open in separate windows and are updated in real-time. A list of settings is available below. More information on this menu is located in this manual under “The Settings Menu.”

Dashboard
Several gauges are present in the display child window. These gauges indicate the current readings of the sensors connected to the Hydra Nemesis 2.7 unit and the state of some important parameters controlled by the unit.

The dashboard window provides the following information:


Pasted Graphic

  • Advanced: ignition timing advance in degrees BTDC
  • Fuel Pulsewidth: injection pulse width in milliseconds
  • Ignition Cut Cycles
  • Fuel Cut Cycles:
  • Duty Cycles: injector duty cycles in percent
  • Vehicle Speed: vehicle speed
  • Left Narrowband: the raw voltage from the left narrowband oxygen sensor
  • Right Narrowband: the raw voltage from the right narrowband oxygen sensor
  • AFR: the reading from the O2 wideband sensor
  • Load: intake manifold boost gauge pressure
  • Battery Voltage: the voltage across the Hydra Nemesis 2.7 unit’s power pins
  • Air Temp: the air temperature sensor reading
  • Coolant Temp: the coolant temperature reading
  • Left Bank STT: the left module short-term closed loop fuel trim
  • Right Bank STT: the right module short-term closed loop trim
  • Throttle Position: the throttle opening value in percent
  • Idle Valve: the idle speed control output in percent
  • Knock Voltage: the knock sensor voltage
  • RPM: is engine speed


Map
The map child window displays a graphical representation of the currently selected map. The graph is either 2D or 3D depending on the type of map selected:

Pasted Graphic

The horizontal and vertical angles at which the graph is presented can be rotated for optimal viewing of any map using the horizontal and vertical scroll bars. Grab and move the horizontal angle and vertical angle widgets with the mouse and release you are finished to reposition the viewing angle.


Map Data
The map data window displays the selected map in a spreadsheet format. The spreadsheet is either 2D or 3D depending on the nature of the selected map:

Pasted Graphic

For the main 3D maps, the x-axis usually indicates engine speed and the y-axis indicates engine load. In such cases engine speed always increases on each column to the right.
