Why import & export
A project (an uploaded BIN plus all the work you did on top) is portable. Export to back it up, share it with a customer, or move it to another INSTATuner install. Import to bring someone else's project in — full SHA-256 verification refuses tampered archives.
The .itproject format
A .itproject file is a zip with five members:
manifest.json— format version, project name, vehicle, ECU IDs, SHA-256 of the BIN, who exported it and when.original.bin— the unmodified binary, byte-for-byte.drafts.json— every cell mutation you made in the editor, grouped by map.audit.json— a trimmed audit trail of editor events for that file.readme.md— a human-readable summary you can open in any text editor.
Format version 1 is the only published version. Newer files made by future releases are refused, never silently downgraded.
Exporting
- Open My Tunes.
- Open the ⋮ menu on a row.
- Click Export project (.itproject). The download starts immediately.
Importing a .itproject
- Open My Tunes.
- Click "Import a project or definition" near the top.
- Drag the .itproject onto the left lane (or click to browse).
- We verify the SHA-256 of the BIN matches the manifest, then create a new project for you with every draft restored.
Up to 128 MB per archive. SHA mismatch is logged and the import is refused.
Importing a TunerPro .xdf
XDFs ship map definitions: address, dimensions, axes, scale, signedness, byte order. We parse them into our internal map registry and attach them to one of your projects so the editor sidebar picks them up.
- Pick the project to attach to (the dropdown lists every BIN you have uploaded).
- Drag the .xdf onto the right lane.
- Open the editor for that project — the imported maps appear under their original TunerPro categories.
Linear math equations (X*S, X*S+O, (X+O)*S, X/D) are reduced to scale + offset automatically. Non-linear equations fall back to identity and warn so you know the conversion was approximate.
DAMOS / A2L
Bosch DAMOS support is on the roadmap. The current import wizard already shows a placeholder so you know it's coming. When it ships, the workflow is identical: drop, attach, edit.
Privacy
Imported BINs land in your private storage on this server only. They never enter the public catalog and never leave your account. Sharing happens only when you export, and only to whomever you hand the .itproject.
