If you are a Vauxhall or Opel owner who prefers DIY maintenance over expensive dealership visits, you’ve likely encountered the diagnostic tool. However, the community is often plagued by firmware issues, "bricked" interfaces, and software mismatches.
Unlike some "fake" high-version firmwares (like 1.99), a verified 1.67 is less likely to contain malicious code that locks the PIC18F458 chip.
The software will query the device. A verified setup will return: "Interface Test Ended Successfully. Firmware Version: V01.67." Installation Tips for a Stable Setup opcom 167 firmware verified
If you have recently purchased an interface or are looking to upgrade, you can verify your firmware version using the following steps:

Key Benefits of Verified 1.67 Firmware: The software will query the device
To run verified 1.67 firmware effectively, the hardware must be capable. Not all OP-COM clones are created equal.
