Opcom 167 Firmware Work [updated] Jun 2026
Firmware flashing typically requires a device with a real PIC18F458 chip ; clones with cheaper chips (e.g., PIC18F45K80) may be restricted or risk "bricking" if updated.
To understand the significance of the "167" firmware, one must first understand the hardware it drives. The OP-COM interface is a diagnostic tool used primarily for Opel and Vauxhall vehicles. While official diagnostic hardware (like the MDI or Tech 2) is available, it is often prohibitively expensive for independent mechanics and hobbyists. This gap in the market led to the proliferation of "cloned" interfaces—hardware manufactured by third parties, largely in China, designed to mimic the functionality of official tools.
These versions are often just older 1.37 or 1.41 firmware with a modified label. They frequently lack the ability to be reflashed and may not communicate with all modules on newer cars.
Getting to work correctly allows for advanced diagnostics and coding on Opel and Vauxhall vehicles manufactured between 1987 and 2021. This specific firmware version is essential for compatibility with the newer OP-COM 200603a software. Key Features and Compatibility opcom 167 firmware work

Run the flash program and select the 1.67 firmware file. Once finished, verify the update by going to in the OP-COM software. Troubleshooting Common Issues
OP-COM firmware 1.67 is widely regarded by automotive enthusiasts and professionals as the definitive "stable" version for diagnosing and programming Opel and Vauxhall vehicles. Unlike newer, often counterfeit versions like 1.95 or 1.99, version 1.67 is considered the latest "genuine" firmware standard capable of working seamlessly with official and high-quality clone interfaces. Key Features and Capabilities
He bought a used OP-COM interface that looked rough but intact: a black dongle with an FTDI chipset, a 16-pin OBD connector, and a USB cable. The first step was straightforward — install the PC software. The ecosystem around OP-COM was informal: community-built packages, patched executables, and a scatter of guides. Mark downloaded a reputable-looking OP-COM package and, more cautiously, a copy of the “OPCOM 167” firmware image others had recommended for his adapter’s hardware revision. While official diagnostic hardware (like the MDI or
