Since your tool just need a model of the car, wouldn't it be pretty "easy" to make it work for other simulators?
For example iRacing, which i've started to run. What kind of info would you need to know about the cars? And can you get it directly out of Telemetry data or how would you collect it?
Sorry i've been away a bit, but i saw that you implemented this function! Very nice!
However, what i was looking for was a "realtime" telemetry function!
Let me explain.
It should simultaneously as you are shown your split time (e.g. Sector1 36.50) by LFS , show either a red or green text in the same font, right below it, with the difference from your entered !target.
So when you pass the split, you'll know if you're inside or outside your designated target time.
Connect to Torsdagsrace A and type !target and you'll see what i mean.
How about adding a !target splitting function so you can see on which splits you need to cut time.
e.g. !target 1.15:00
Will automatically show for each split how close i am to making 1.15:00.
