Hello RealDash Team,
First of all, thank you for your support and for developing such a great platform.
After a lot of testing, I can confirm that we have successfully connected the MoTeC M84 to RealDash via CAN Bus. We are now able to receive all of the important engine data, including RPM, coolant temperature, throttle position, and other channels. Everything is working correctly.
However, there is one remaining issue:
Battery Voltage (VBAT) does not appear to be transmitted over CAN.
We have searched through the available CAN data, monitored all CAN frames, and compared the data with MoTeC Manager. While the ECU clearly displays battery voltage in MoTeC Manager, we cannot find any CAN message that contains this value.
Interestingly, we have noticed the same situation with other RealDash CAN definitions, such as some GMC XML files, where battery voltage is also not defined. This makes us wonder whether battery voltage is commonly excluded from the CAN stream unless it is explicitly configured.
Our questions are:
- Is battery voltage transmitted by the MoTeC M84 over CAN by default?
- If not, is there any way to configure the M84 to transmit battery voltage?
- Is there a recommended method to locate this value if it is hidden within another CAN message?
- Has anyone successfully displayed battery voltage from an M84 in RealDash?
Any advice or experience from the RealDash or MoTeC community would be greatly appreciated.
Thank you.
