- **MED17.5.5 threads exist** with users requesting and receiving IMMO OFF files [1], [7], [12]
- **File-based approach**: Users exchange pre-modified files via PM, suggesting EEPROM or full-file modification [1]
- **Successful confirmations**: Similar ME7.1.1 IMMO OFF work was confirmed working in testing [2], [3]
## What the sources do NOT provide:
- Specific memory offset locations for IMMO data in MED17.5
- Pin/MAC extraction procedures for this platform
- Checksum or security algorithm details
- Tool recommendations (KTAG, Galletto, J2534 method compatibility)
For detailed MED17.5 IMMO OFF methodology, you'd need to consult specialized tuning resources or contact experienced community members directly through the MHH forum.

**Safety reminder**: Writing IMMO modifications to an ECU will disable immobilizer security—only perform on vehicles you own or have explicit authorization to work on.
