If you are looking to update your specific device, I can help you identify if your hardware is compatible. Do you know if your board has the chip, or
Version 1.67 was released by the original manufacturer (Scantool) around 2012-2013. Here is why it remains the most requested firmware:

the OPCOM interface and identify the PIC18F458 chip.
The Opcom interface, particularly version 167, remains a staple for enthusiasts and independent garages working on pre-2010 Opel, Vauxhall, and Holden vehicles. Unlike later USB-to-CAN adapters, the Opcom device relies on specific microcontroller firmware to communicate correctly with vehicle ECUs. A verified OP-COM_Firmware_1
OP‑COM (often spelled Op‑com ) is a Windows‑based diagnostic tool designed specifically for . It connects to a car’s OBD‑II port via USB and allows users to read and clear fault codes, view live sensor data, perform actuator tests, program immobiliser keys, and carry out coding/adaptations across most electronic control units (ECUs). Many enthusiasts and small workshops rely on OP‑COM because it offers functionality that rivals much more expensive professional scanners, but at a fraction of the cost.
The is widely recognized as the "gold standard" for genuine and high-quality clone diagnostic interfaces used for Opel and Vauxhall vehicles. While many clones claim to have "later" versions like 1.95 or 1.99, these are often older firmware (such as 1.39) faked to appear more modern, whereas 1.67 is considered the final stable and genuine release for professional-grade hardware. Core Capabilities of Firmware 1.67
Because genuine OP‑COM interfaces are relatively expensive (and have limited distribution), the vast majority of devices sold on marketplaces such as AliExpress, eBay and Amazon are . To make these clones appear more attractive, sellers often modify the firmware version number to something that sounds newer, such as 1.70, 1.78, 1.85, 1.90 or 1.99. None of these versions were ever released by the original manufacturer – they are entirely fake. Do you know if your board has the chip, or Version 1
It provides reliable communication with both High-Speed and Mid-Speed CAN buses, essential for accessing modules like the Engine, Transmission, and Infotainment. Identifying a Quality Interface
This article provides a deep dive into the 167 firmware, why it is sought after, how to verify it, and how to safely use it for your diagnostics. What is OPCOM and Why Firmware Matters
This article provides a comprehensive overview of the V1.67 firmware, why it is highly regarded, how to verify it, and best practices for its use in 2026. What is OPCOM Firmware V01.67?
The magic phrase refers specifically to the firmware inside the hardware. In an ideal world, the software version and the firmware version match. In reality, due to Chinese clones and bootleg flashing, they rarely do.
