New in update:
  • Tunes no longer replace the stock car. Tunes will now be a selectable upgrade in-game. newinstall.PNG
  • However this means that every time you make a new tune you will have to go to "general settings" and click "clear car preview cache" for them to appear in-game, or simply restart the game (just use "clear car preview cache" it is must faster).
  • UI has been slightly updated, you no longer have to click install tune or save tune, only click apply if you have made any changes in "Basic Tuning", "Advanced Tuning" still saves automatically.
  • You should now be able to create tunes of modded cars who have a data folder and not a data.acd file.
  • Many have reported that in some cases Engine Swaps do not give the car more power. Try turning off traction control and report back.

If you make a cool video using a tune made with this tool, send it to me and I'll put it up here.
Assetto Corsa Car Tuner:
This program allows you to tune any car in the game. You can do so with either "Basic Tuning" or "Advanced Tuning". Basic Tuning let's you modify preselected data like torque, turbo's, wheel drive and more! Advanced Tuning is for the more experienced tuner, and let's you mess around with the data files. Once you have made your changes, click save tune (If you used Basic Tuning click "Apply" first), then install tune to have it available in-game.

The program saves tunes as a seperate car that is selectable as an upgrade in-game, the original car is therefore not changed!

  1. Unpack CarTuner.zip
  2. Open program by clicking the "Assetto Corsa Car Tuner.exe".
  3. Click "Select Assetto Corsa Folder" and a dialog window will pop up, select your Assetto Corsa install folder, it's usually under Steam/steamapps/common/.
  4. Select the car you wish to tune.
  5. Type a name for your tune in the textbox under "New Tune Name:" and click "Create New Tune". The program will automatically select the tune you just made.
  6. You can now modify the car using either "Basic Tuning" or "Advanced Tuning". When using "Basic Tuning" remember to click "Apply". "Advanced Tuning" let's you access the data files, any edits to these will auto save.
  7. Once you have made your edits simply boot up the game, and when you select the car you tuned, it should let you select upgrades, like so: newinstall.PNG
  8. You can do these changes while having the "Assetto Corsa Launcher" open. However, you will have to go to "general settings" and click "Clear car preview cache" for new tunes to appear. Tunes that already appear as selectable, can be modified, and the new changes should load next time you start a race.
  9. If you have any bugs, report them here :)
The tunes that you make do not work online, unless the tune has been installed on that server. Each player will then have to have the same tune installed for it to work.

My program is essentially just an advanced text editor that manages files, and can make quick changes using basic tuning. To unpack the files it uses the program called QuickBMS. For ease of install the quickbms.exe file is included in the zip folder. QuickBMS however is capable of much more, check it out here:

If you have any questions or suggestions feel free to write them in a comment on this post.

Does what it says on the tin well. Only issue that it can lead to major space bloat because it copies and pastes all the assets from the original file to the new one in order to make a tuned version. For those who like to keep their storage clean and free of bloat, this can be an annoyance, especially as a tune can mean duplicating over 100mb of assets depending on the vehicle and its details.
dosent work at all
This use to work excellent now it does nothing at all
Must have something to do with ac maybe cause now when you go to select the folder location for the tuner it does nothing
software is bugged, i cannot click on anything,
the car tune just falls threw the track am sure this is a bug because the stock car doesn't fall threw the track plz fix.
This tool is insanely fun! There were quite a few modded cars which were not functioning properly as in hitting the limiter too early due to wrong gear ratios, etc.

Also great fun for making your own dream cars. Absolute must have mod for people wanting to tinker with their cars!
I just want to know how to do this select assetto corsa folder step
Work like is supposed to be.
From any people is in trouble with "Select Assetto Corsa Folder", you need is extract admin. Will be work fine.
doesnt work, kept saying wrong folder is selected when i select the assetto corsa folder
When i select cars map it says "Not right map selected" and i cant select any car. Someone pls help?
Great tool to unlock the car's data files. I'm having trouble sharing the cars that I have modified with friends though. Many kinds of errors can prevent them from working properly on other people's computers. I am just sharing the entire modded car file with them from the assettocorsa/content/cars folder.
I can't do anything when I select a folder.
When I apply settings, nothing happens.
it does not choose the car set
I understand the whole program but i cannot charge the archives of the game, equal to do nothing
When i download it, it downloads the v1.50 instead of the v1.53 and the 1.50 crashes everytime i try to tune a car
It work perfectly as is, very easy to use for engine swapping with other existing mods. Definitely recommend
This is a great tool! It´s really nice for personal use to play around and learn how to setup car physics to your liking and if you are into car modding.
Copies files and then crashes when I try to "create new tune", also crashes when I hit "apply"
