Help with RealDash on Pi4 + CAN HAT (only RPM and Oil Pressure working)

General

Hi everyone,

I’m running RealDash on a Raspberry Pi 4 using DietPi OS and a CAN HAT. I uploaded the XML files for my MoTeC M130 ECU, but right now only RPM and Oil Pressure are showing correctly on the dash. None of the other parameters (TPS, coolant temp, boost, AFR, etc.) are working.

I’m not sure if the issue is with:
• The XML configuration (maybe incorrect CAN mapping?)
• The CAN wiring/termination (I measured ~90–110 Ω between CAN H and CAN L at the dash connector, car off)
• Or something with the Pi4/DietPi setup

Has anyone faced this before, or can guide me on how to debug? Do I need to adjust the XML or set something in M1 Tune for proper CAN transmit?

Any advice or example configs for M130 + RealDash would be greatly appreciated.

Thanks in advance!

If you can see constant flow of data in RealDash CAN Monitor, it probably is not a wiring or CAN bus resistance issue. That leads to the issues in CAN XML configuration.
