Here’s a ready-to-use forum-style or blog post regarding MultiECUScan ELM327 port settings for 2021, which remains relevant for current use as well.

• Engine (ECM)
• ABS
• Airbag (ORC)
• Body Computer (BCM)
• Dashboard (IPC)

1. COM Port Number: Change this to COM1, COM2, COM3, or COM4. Why? MultiECUScan struggles with high COM port numbers (e.g., COM17). Keep it under 10.
2. Latency Timer (msec): This is the magic setting.
   • Update MES to the latest version (post-2021 updates improved CAN handling)
   • Try a dedicated "modified ELM327 for MES" – generic v2.1 adapters often lack proper timing.
   • Use a USB 2.0 port, not USB 3.0 (some adapters misbehave on 3.0)
