ECU Original Files (ORI) Database

Welcome to Tuningbot’s ECU Original File Database (ORI) — a curated library of factory ECU binaries
Every ORI file is an unmodified, verified stock read, essential for restoring ECUs, comparing modified maps, or diagnosing corrupted software.
Use the filters below to browse by Brand, ECU Brand/Model, HW, or SW. Each record provides clear identifiers, making it easy to match the correct file for your specific control unit.
Designed for professional tuners and workshops, this archive focuses on data integrity, consistency, and traceability.
Whether you’re reverting a bad tune, analyzing calibration differences, or preparing a new project, starting from a clean, certified ORI ensures safety and precision.

What is an ORI file? An ORI (original) file is the factory ECU software readout — a reference map used for restoring and comparing modified binaries.

How do I choose the right file? Match Brand → ECU Brand → ECU Model → HW → SW. When in doubt, use both HW and SW identifiers to narrow the list.

Can I use an ORI with a different SW version? Sometimes yes — within the same ECU family — but always verify hardware and software compatibility before flashing.

Are the files verified? Yes. All ORIs are checked for completeness and checksum integrity.
