A tool for RaceRoom Racing Experience which shows you launch data.

Run the tool, change the Stop Speed to whatever you want, and then it will show you information about 0 to that speed runs. If the timer starts running without the car actually moving, increase zero_threshold in config.json.

You can check out pre-compiled versions in the Forum (might be outdated), or run the setup.py file to compile (into a directory called R3E_Launching). Another thing to note is that setup.py requires Python3, and py2exe which you can install by running:

$ pip install py2exe
