In Assetto Corsa free version, there are literally a ton of great starting point 'mods' for usage approximating various race cars.
In this area I will plan to host a few specially tweaked 'mods of mods' where I have run the loop a few times with Motec data from the simulated lap, compare with some actual info (such as recorded lap video, lap times, section splits, etc.) and ask AI to help recode the next iterations of Assetto Corsa car mod and OpenModelica model (for analysis of variables and optimization) to get closer to the real race car.
It will be possible for others to get an even better approximation by putting real track data (Motec or other sensors) and really making the OpenModelica model loop for optimization more valuable to going faster.
