Have you tried to contact Motorsport Electronics (ME) if they know an adapter that is tested with their ECU?

Hello, I’m jumping into this thread; I’m having an issue with the ME442. I can’t get the AFR readings to show up in RealDash. All I see is a number—like 13.9—that barely changes, and even then, only after a long delay. However, when I connect my PC to the ECU, the AFR readings show up correctly on the PC. I’m using a USB connection via an Android head unit. Do I need to change any settings?
