Editing Files with TunerPro


rpm limiter

A constant, sometimes called “scalar”, is a singulary value in binary file. A constant might be used, for example, to represent the maximum rpm of the engine.

To edit a constant select the constant from constants list. The desired parameter and its current value are displayed in the constant editor. You can select the number in the edit field and type in the value you desire.

When the item is saved (pressing save button) the chosen value will automatically get rounded to the nearest possible value in the bin.

Another chance is to hit the keypad + and – keys or Ctrl + “+” or Ctrl + “-” on the main keyboard to increment or decrement the values to their nearest possible values.


lambda removal

A flag represents a bit within a series of bits. A bit can only be set or clear (1 or 0). Each bit, therefore, can represent a “switch” or “flag”. For instance, a flag could be used to enable or disable a feature, where a bit value of 1 represents “on” and a bit value of 0 represent “off”.

A flag in TunerPro has two states, set or not set.

To edit a flag, select the desired flag set from the flag list. You will be presented with the flag into in the flag editor. Check or uncheck the values you wish. A checked item means the bit for that item within the mask is set (=1). No check means the bit is cleared (=0).


requested torque

A table, also called map, is a group of values representing the output on two or more axes where each value is a cell in a table. For instance, the torque requested at a given load (% of accelerator pedal) and RPM might be represented as a 3D table in a binary where the X axis is the RPM, Y is the load, and Z is the output in Nm.

To edit a table, double click the table in the table list. This brings up the table editor. Edit the values you wish to edit using the same guidelines as the constants.

Range Selection

You can select a range of cells in a table by either left-clicking on the first cell in the range and, while holding the mouse button, dragging the mouse to the last cell in the range. With a range of cells selected, you can increment or decrement the values in the selection range all at once, or make use of the table functions in the table editor toolbox to modify the selected range. You can also copy and paste data to and from the selected range.


Table data can be copied to and pasted from the Windows clipboard. Once you have selected a cell or range of cells in the editor, you can copy the data to the clipboard by either pressing control + c or by right-clicking in the table and selecting “Copy Selection”. When data is copied to the clipboard, it can be pasted elsewhere into the table or into another program such as Microsoft Excel. To paste data into a table, select the first cell and hit control + v, or right-click in the table and select “Paste starting at cursor”.

Table Tools

The table editor toolbar has a group in it that allows you to edit the current selection with special functions, such as smooth, offset, multiply, etc. This allows you to, for instance, multiply an entire row, column, or table by a desired factor, or add to an entire column.

  • Offset adds or subtracts to the values
  • Multiply multiplies by the desired factor
  • Divide divides by the desired factor
  • Cpy frm cmpr copies the corresponding values from the comparison bin
  • Fill w/ value replace selected area or single cell with a chosen value
  • Smooth allows a smooth transition among adjacent cells (values from 0.01 to 0.99)

Input the factor/offset you wish to use. You may use a “-” to input negative numbers. Select the area you want modify and then click “Execute”.

If you would like to work in %, please select the area you require to modify, use “Multiply” function and put 1.1 as value in order to increase +10%. For example, if you want to increase +25%, you have to put in value area 1.25 (.25 in the desired percentage).

You can see units of maps and axes opening the 2D/3D view. To open this view just click on button “show table graph” or F11 shortcut on the keyboard.
