New update (I know this is not the original car tuner, but it will be included in it through a second button when I get something "playable")
Done:
-Build a database from user content folder to be read by the app --> OK
-Option to choose which tracks/cars to include in the database --> OK
-Create a shop with cars/skins from content folder --> OK
-Start a hotlap or quick race mode from the app on any track config from content folder --> OK
-Display car data from any car in the shop (traction, power, torque, weight, hybrid if available), data is set at 13% default loss of power through drivetrain--> OK thanks to database building directly from content folder
Still do do:
-Save/Load current progress from a "slot" --> should be "easy" enough in excel
-When building the database, sort cars by traction/power, etc... to use as opponents in events--> in progress
-Build events from sorted cars/tracks database (Clubman cup, FF challenge, FR challenge, and the like....)
-
Read results from race/hotlap session (would need some race_out.json from people reading this topic as I'm not able to do too much racing in AC while working/coding/having a real life outside of this 
) --> need some race_out.json from quick race and hotlap events in CM
-Car tuning --> really after a stable release is OK as it would mess with user's content folder and need some work....
Bulding database takes a few minutes, depending on the number of cars in the content folder (only 692 for me on a high-end computer it takes about 2 minutes) but is only needed once (unless content folder is modified after that)
It's just something I'm doing as a hobby as I always dreamed of a GT like game but with a more robust physic engine (not saying AC is perfect, I play many sims but AC is the most easily moddable ^^ )
Hope to get something "playable" in a month or so if I get enough time for this!
