Remove the Opcom 167 PCB. Locate the (or the 2585 variant). Unlike the older 160 version, the 167 does not have a convenient ICSP header. I had to solder six jumper wires to the following pins:
for clone diagnostic interfaces used with Opel and Vauxhall vehicles. Unlike later versions (such as v1.99), v1.67 is built on the high-quality PIC18F458 microcontroller opcom 167 firmware work
: Version 1.99 is frequently a "fake" firmware label applied to non-upgradable hardware, leading to instability or failed connections with newer CAN-BUS models. or help identifying if your hardware chip is genuine? OP-COM 1.67 cable for diagnostics and coding Opel 1987-2016 Remove the Opcom 167 PCB
A: No. The memory map and CAN controller initialization differ. You will brick the device. I had to solder six jumper wires to
| Firmware | Best For | Weakness | |----------|----------|----------| | | Basic reading on old cars | No CAN, many bugs | | v1.45 | Immobilizer & key programming | Slow live data | | v167 | Balanced daily use (2000-2012) | No advanced coding | | v1.99+ (MDI clone) | Full SPS/GDS2 | Expensive, complex |
: This firmware usually runs on the PIC18F458 microcontroller. If your device uses a "fake" chip (marked as OP-COM but not a genuine Microchip PIC), attempting to flash or "downgrade" the firmware will likely brick the device.
