There are several apps listed here, but some of them don't link to any download location
http://www.projectcarsgame.com/apps.html there are some for Android and Apple devices.
You have to set
Shared Memory to true. I think the setting is in the hardware tab of the graphics settings.
@mister dog says that if you use shared memory & watch a replay there is a bug which can wipe your profile, so you might want to research that, or be careful that you know what the setting is before you watch a saved replay
The particular one I used was from
http://www.tomshane.cz/profiler/
You just install that. There are no instructions that I could find.
but...
Start the profiler before starting pcars.
Find the
connect icon right at the top.
Start PCARS.
Go into free practice & do some laps.
Alt -tab back to the profiler & you will see all the recorded lap data. CLick the disconnect & you will be able to look through & compare all the data from your laps.
Then have a look at the Graphs & indicators menus, you can choose from some preset displays for tyre temp, wear damage etc...
I created 3 custom layouts - analysis (with telemetry graphs), Pitboard(with all the live telemetry gauges etc..) and Recording (which only shows the lap times - I thought this would be useful when I just want to record the laps without the overhead of updating the live gauges / graphs.
