Load your setup.json — every value is explained in plain English (tyre pressure in psi), and one click turns a twitchy setup into something you can drive. Everything stays in your browser.
Documents\\Assetto Corsa Competizione\\Setups\\[Car]\\[Track]\\ — that is where ACC stores your setups. Load the file of the setup that is giving you trouble.
Pro setups from the internet often feel undriveable to beginners. This tool reads your ACC setup file (setup.json), explains every value in plain language — including the tyre pressure conversion to psi — and, at the press of a button, produces a calmer, more forgiving version to download.
Only safe fields are toned down: more TC and ABS, more rear wing, brake bias forward, softer anti-roll bars, less differential preload. Springs, dampers and ride height are left untouched, because wrong values there can make a car worse. Everything runs in your browser, nothing is uploaded.
Under Documents\Assetto Corsa Competizione\Setups\[car]\[track]\. That is where ACC saves all your setups as .json files.
The setup.json stores a raw value, not a real unit. The approximate psi value comes out of 20.3 + raw value × 0.1. This tool converts that automatically.
Nothing is uploaded. The file is read and processed purely locally in your browser — there is no server that ever sees it.
