Unsigned
Client-side · zero file upload

Strip WinOLS signature locks, privately.

Upload a stock + locked ECU file. We detect and remove WinOLS hexdump signatures, NOREAD markers, and tags — and prove the result is clean. Your files never leave your machine.

Scan + visual verification are free. Pay only to download the clean file.

Files never leave your browser

Processing runs locally via an in-browser engine. We never receive, store, or see your tuning files — there is nothing to leak or subpoena.

See the locks vanish

A three-way hex compare and map-surface heatmap show the signature noise in the locked file disappearing in the clean output — before you pay.

Proven, not promised

Every unlock is re-scanned and diff-audited. A green VERIFIED banner means the output is byte-clean against the same gate our regression suite enforces.

Handles real ECU dumps

Bosch MED17, MG1, VGS-NAG3 and more — from 0.5 MB to 32 MB. Signed maps, NOREAD markers, and injected tags all detected and removed.

The honest workflow: verify first, pay last.

Load your stock + locked pair, watch the engine find and remove the signing, and inspect the result cell-by-cell. The download gate is the only thing that costs a credit — and only once the output passes verification.
