Many "Chinese clones" marketed today come with firmware 1.95 or 1.99. However, the Vauxhall owner community frequently warns that these are often designed to work with low-cost, inferior chips that cannot be reflashed.

Using firmware for a PIC18F2580 on a PIC18F25K80 hardware. Solution: Only use firmware labeled explicitly for "167" or "clone V2." Check forum threads on Digital-kaos or MHH Auto for verified dumps.

Updating the OPCOM 167 firmware is important for several reasons:

: Unlike some later "fake" versions (like certain 1.99 versions which are locked or "empty"), 1.67 is often capable of being downgraded or upgraded to match specific software requirements without "bricking" the device.

Here are some common issues that may arise when working with OPCOM 167 firmware:

Surprisingly, Opcom 1.45 firmware (latest) may fail on 1990s KWP2000 cars (Vectra B, Calibra). Workaround:

, automatically selecting the correct pins on the OBD connector for various communication protocols like KWP-2000 or CAN Why Version 1.67?
