Protezione della lettura OBD

OBD Reading Protection — Anti-Read via OBD for Tuned ECUs

Protezione della lettura OBD is a professional ECU calibration service that prevents third-party tools from reading out your tuned file via the OBD diagnostic port.
With the protection enabled, leggere attempts are blocked, while write/programming, dealer software updates and normal diagnostics remain fully available (where platform allows).
This is the ideal safeguard for tuners and workshops who want to protect their intellectual property and avoid unauthorized copies of bespoke calibrations.

What OBD Reading Protection does

Modern ECUs expose multiple diagnostic services over OBD (UDS/KWP/Manufacturer-specific). A readout usually leverages seed-key access, service $22/$23/$27, or vendor-defined routines.
Il Protezione della lettura OBD calibration edits the ECU’s access control and/or read routine mapping to deny memory readback from flash areas that contain your calibration.
Crucially, it preserves essential workflows:

  • Programming (write/flash) of updated files remains allowed (master tools and bench/boot methods remain unaffected).
  • Dealer updates e standard diagnostics (DTC read/clear, adaptations, service functions) stay operational where supported by the platform.
  • In many ECUs, virtual read still works (tool fetches stock file from its database), but reading your tuned image via OBD is blocked.

When to use OBD Reading Protection

  • After delivering a custom remap and you want to prevent competitors from copying the file via OBD.
  • In multi-installer networks (fleet, franchise, dealership) to protect IP across branches.
  • Per motorsport and R&D vehicles where file confidentiality is critical.
  • As a deterrent in rental/lease or track-day cars that should not expose the tune.

Vantaggi e note tecniche

– Protects the calibration image from unauthorized extraction over OBD.
- Conserva serviceability (diagnostics & updates) intact on supported platforms.
– Works alongside your normal tuning workflow (OBD write, bench/boot procedures).
– Reversible: the protection can be removed if you need to revert to stock or migrate to another configuration.

Importante: behavior can vary by ECU family, tool vendor and firmware level. Always test your specific toolchain (master/slave, brand, protocol) after enabling protection. This feature is intended for professional use.

Protection can be applied to

  • BMW — Bosch EDC17
  • VAG Group (VW / Audi / Skoda / SEAT) — Bosch EDC16 / EDC17 / ME7 / MED9

Additional ECU families and brands are available on request. Coverage is continuously expanded; if your platform is not listed, contact support with ECU family, microcontroller and tool used (OBD/Bench/Boot).

Note on dealer visits: on many platforms, dealer online updates remain possible; after a dealer flash the tune and protections may be overwritten by stock software and need reapplying.
