I created a small python scripts that will check all available PIDS  on the motorcycle. This way you can see what will be available to you in DMD2 for your motocycle. On my motorcycle (Honda CRF 300L Rally) majority is not supported. I will try some custom and extended PIDS maybe I can find gear indicator which would be a nice feature. I’m hoping that developers will fix Voltage issue and add ATRV command for the ELM327 dongle owners.

You can download the script at: https://github.com/omadon/Moto_OBD2_Discovery

Below is the example from my bike:

 

C:\OBD2>python OBD_supported_features.py
Available serial ports:
1. \.\COM3
2. \.\COM4
3. \.\COM5

Enter desired serial: 2

CRF300L Rally 2021 everything works except battery voltage (and the fuel indicator but this is probably not exposed over obd2). I’m using ELM327 V1.5 (Single Board PIC18F25K80). When using Torque on the same tablet it can normally read battery voltage and other sensor info. If someone can help me troubleshoot this it would be great.

There are two ways to read the Battery voltage, from ECU or from dongle, in the new DMD2 Beta in OBDView Settings there is an option called “Get Voltage from Dongle”. Can you tell me which other sensors work in Torque that do not in DMD2?

Finally found some time to troubleshoot missing voltage value using ELM327 adapter on my Honda CRF 300 Rally. I seams that for “Get voltage from the dongle” you are using STVR command which is part of the extended ST command set available only on the new Obdlink adapters. There is original ATRV command which is compatible on both Obdlink and ELM327 adapters. Is there a way that you can add both options in the OBD configuration window?

I tried the beta version and the “Get Voltage from Dongle” option but the voltage was still 0. I presume for this option you use ATRV command instead of reading specific PID. In Tourque get voltage from the adapter is working ok.

I will check every PID in Torque and let you  know  whats is working and also all PIDs in the DMD2  for the Honda 300 Rally.

Is it possible for you to share which PIDs are you using for fuel gauge, voltage and gear indicator. This way I can check what is not working and maybe find an alternative.
