ECU Archive Software is the Windows desktop client for our ECU file archive. Install it once, paste your key, and the whole catalogue opens inside the program — browse by category, search by brand or control-unit code, and pull any file straight to your PC.
One credit downloads one file. Credits live on your key, not on an account, so the same key works in the program and on the website — there is nothing to register and nothing to log into. Your remaining balance is shown at the top of the window and is counted on our servers, so it is identical everywhere you use the key.
Windows 10 or 11, 64-bit. No .NET installation needed — the runtime is inside the program. An internet connection is required to list and download files.
Unused keys lose 1–10 credits per month after 30 days without a download. Keys used at least once a month are never reduced.
