You will receive a zip file containing both the Qualy and Race setups (plus 2 eSports setups) of the specific car & track you chose. If instead, you purchased a bundle, you will receive a zip file containing all Qualy and Race setups from each of the 23 ACC tracks.
You can also use them on PS4/PS5 and Xbox! The only difference is that while you can copy and paste the setups file on PC, on PlayStation and Xbox you will instead need to add each value manually on the setup section after you’ve started the session in ACC. In order to read the value you will need to visit accsetupcomparator.com and upload the setup file (the json one, not the zip) and then manually add each value on your ACC setup section. Always remember to make sure you’re using the same track and track from the setup otherwise the setup won’t work.
The short answer is: “it depends”. It mainly depends on what current setups you’re comparing them from, though from a standard ACC setup you can easily expect to find 4 to 6 tenths (or more) in lap time. From other setups providers it’s difficult to compare, though our sim racers seem to like them a lot and immediately get up to speed after a few laps.
Regarding different cars, no, unfortunately, you can’t since the setup won’t be properly loaded by ACC. So you’ll always need to make sure that you paste the setup in the exact car of ACC’s setup folder. But regarding the track, since version 1.9 you can now use the same setup on different tracks without any issue.
Remember though, even for EVO and non-EVO cars it makes a difference and the setup will not work on the “wrong” car (Example: The Audi RS LMS EVO and Audi RS LMS EVO II can’t run on the same setup!)
