No need to, i get what you mean. For that purpose i use MoTec i2 Pro, the game outputs suitable telemetry for it. i2 Pro is free to use for this purpose so we get one of the best programs in the market (it's very expensive if used with data gathering modules in real life...)
You need to make a few changes to your .PLR file, located in Documents\SimBin\Race07\Userdata\[player name]:
Data Acquisition Rate="10" // rates 1, 2 ,5, *10*, 20, 50, 100
Data Acquisition In Race="1"
Data Acquisition EXE="C:\Program Files\MoTeC\i2\1.0\MoTeC.exe"
Data Acquisition File="E:\SimBin\RACE 07\UserData\vehicledata.spt"
MoTeC LogFolder="C:\Program Files\Steam\steamapps[steam_username]\race 07\MoTec"
MoTeC Minimum Time="20" // minimum MoTeC recording time (sec)
MoTeC Multiple Logs="1" // generate unique filename for each new log
That's a copy of mine, SteamUser masked of course... Check those marked red and change them to fit your needs. EDIT: You need to create a folder where the telemetry-files will be saved, it's not autogenerated. I use "MoTec" named folder but it can have any name you want..
