If you have a Razer Chroma keyboard and/or mouse, then this application will utilize them as RPM indicators. It will also display your current gear to the number row and whether or not traction control and abs is enabled represented by an illuminated 't' and 'a' respectively.
The colour of the RPM indicators are now fully customizable and are set within the application and you can also adjust the update frequency (see the included documentation for more information).
This program is a standalone application and requires no installation as such, simply extract the downloaded *.zip file to a location of your choice, e.g. program files, and then you can right click on the *.exe -> Pin to Taskbar/Send To -> Desktop to create shortcut.
See the included documentation for more information.
