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
  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.

It works perfectly here. Very easy to correct some absurd default values on AI.INI file which make certain cars being impossible to race in street circuits.
it used to work in 1.50, but the 1.52 doesn't give me any cars to select even though i did the exact thing when it was still 1.50 and it worked just fine. So can you give us the previous patch to download. Thank you (:
To get it working, you must extract the Car Tuner file to the AC install folder, if it's on another drive it won't recognize the AC install folder.
when i tune my cars , there are some cars that turns blue and i dont understand why
doesn't work
Great program! I'm working on a nutty tune of a Corvette Z06 and I'm swapping the stock transmission with a 7 or 8 speed dual-clutch. I still haven't decided whether I'd have 7 or 8 gears, but that's the least of my problems now, because the car recognizes I have 7 gears at the moment, however it has no power.

What do I do, or what did I forget?
Thank you very much!!!! One of the coolest yet simplest mod i've discovered
Now i can swap the Lotus engine to a Fiat 500 ;)
doesnt select folder even when its the right one
Just doesn't work for me. Despite having twice the engine power and a bigger torque after recalculating curves with the new datas, the car I used still has the exact same speed. Am i doing something wrong ?
Working nice and i have question can i change the stering angle in advanced tuning because i cant find option?
don't work :(
works great, swapped Zonda V12 into E30 lol
Currently doesn't work...creates and uploads the tune without any of the new settings
Don't work.
It doesn't find the folder and import cars so I can modify
Works great
the engine swap featured seemed to work, but when trying to increase the torque and turbo also decrease the weight nothing worked. i watched quite a few videos on the software and nothing worked
For anyone wondering why there isn't anything coming out of the columns, you have to do this before :

"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."

Once you've done that, you'll be editing a tune, and options will be available to you
Just installed the tuner. Trying to do a motor swap but nothing comes on the drop down menu any help
nothing works. sure would be cool if it did
