  • split cursors for separate measurements per lane


  • generator to capture 'proper' track maps with several display modes
  • A and B driven lines can show two telemetry parameters
  • shows absolute and delta cursor positions
  • zoom and pan, with follow cursor option


  • framework for scriptable dashboard design
  • multiple dashboards driven by loaded sessions, live sessions or scripts

Download and installation

The current 64 bit version, 0.12, can be downloaded here.

The current 64 bit version, 0.12, can be downloaded here.

If your virus software throws a warning, fear not, the installer has been scanned and cleared with Avast.

Version 0.12 is the first public release and any installed versions prior to v0.12 must be uninstalled in full before installing v0.12: Please remove the "C:\Users\Documents\pCARS Telemetry" folder, and delete the registry keys "HKEY_LOCAL_MACHINE\SOFTWARE\Leistad Systems Development" and "HKEY_LOCAL_MACHINE\SOFTWARE\Leistad Systems Development".

The minimum OS requirement is Windows Vista, Windows 7, Windows 8, 32 or 64 bit.


If the application crashes, please put the files "_crashlog.txt" and "_minidump.dmp" in a zip archive and attach it to a posting describing the circumstances of the crash. These files can be found in your "Documents/pCARS Telemetry" folder.

The distribution comes with some installed scripts which effectively are 'applets' that extend the application. They can be found in the folder "managed_scripts" inside the "pCARS_Telemetry" folder. They can be managed using the Script Manager. The scripts are using the gui library and have registered buttons on the Script Toolbar (the leftmost toolbar at the top of the window). Clicking these buttons will toggle the guis open and closed. The installed scripts are:

  • BigNums - showing a variable number of parameters in a row colum layout
  • CSV-Export - CSV telemetry data export
  • CursorStats - computes statistics for a parameter using the delta cursor pair for the range.
  • Dash1 - example instrument panel, speedometer, rev counter and timing
  • Dash2 - example instrument panel, speedometer, rev counter, timing and controls
  • Dash3 - example instrument panel, gauges for four selectable parameters
  • Dash4 - example instrument panel, temperatures, wear and g-forces
  • Dash5 - example instrument panel, "minigraphs" of a few parameters
  • GraphFilter - plots a graph with a low or high pass filter applied
  • Lap2Lap - plots the lap to lap difference for a parameter
  • LapHistogram - histogram tool applet
  • LapStats - tool for computing statistics for a parameter over a lap range
  • LiveaStats - shows live parameters with running averages and maxima
  • LiverNumsRecorder - performs ad hoc live recording. Saves to CSV files
  • RaceInfo - using dash_module.lua to create an race infor intrument panel
  • ScatterStats - tool to perform scatter plot and statistics for two parameters

So far the documentation is brief and incomplete - the user manual proper is a WIP. It can be found on the apps Help menu, or in the "Documents/pCARS Telemetry/manual" folder. In the manual folder you will find some additional text files. The file "user_manual.txt" is a general operations manual, the file "scripting_manual.txt" is the beginnings of a reference manual for the scripting, the file "dashboard_manual.txt" is the documentation for the dashboard framework. These are raw text files hacked together while coding, so they're not too friendly. Eventually it will all be reworked and included in UserManaul.pdf.
