We need the OBD PID commands and how to interpret the returned data. Since this is not easily available for most vehicles there is not possibility for us to provide a time estimate.
If you find that an existing vehicle profile reads data correctly, please let us know, but please DO NOT keep using the incorrect vehicle model with live data.

Could be that the PIDs we use for an already supported vehicle model could work. Here’s what you can do once you have access to the vehicle and a dongle;
Select the actual model of your car, save it
In vehicle settings, change the model of the saved vehicle to one that you suspect has compatible OBD commands (just any model will not work, it needs to be compatible)
Link the vehicle via OBD (details here; OBD Connection )
Select the correct vehicle model again
After verifying that the data is read correctly (or even partially correctly) notify us that the OBD commands for vehicle model X also works for vehicle model Y.

Dear Katya,
Thank you for your response regarding the Alfa Romeo Junior Elettrica Speciale. I understand you need more detailed information about the OBD PID commands and how to interpret the returned data. Here are the relevant technical details for my vehicle:
⸻
Vehicle Details: • Model: Alfa Romeo Junior Elettrica Speciale (Classic car EV conversion) • OBD Protocol: CAN Bus (ISO 15765-4) • Baud Rate: 500 kbps • CAN ID Range: 0x7E0 - 0x7EF (ECU Addresses)
⸻
Powertrain and Battery Systems: • Motor Controller: Please let me know if specific information about the motor controller (e.g., Curtis, Hyper9, or a custom system) is required. • Battery Management System (BMS): The vehicle uses a custom BMS, which may affect the available PID commands.
2.Sample OBD PID Commands
PID(HEX)- DESCRİPTİON - NOTES- FORMAT
2101-battery voltage-Total packvoltage- mV
2102-battery Current-Current being drawn or supplie - mA
2103-State of Charge (SoC)-Remaining battery percentage-%
2104-Cell Temperature-Hottest cell temperature in the pack - °C
2105-Motor RPM -Current motor speed-RPM
2106-Motor Torque-current motor torque- Nm
Interpreting Returned Data: • Example: When the 2101 command is sent, the response contains a 16-bit value representing the total battery voltage. For instance, if the response is “07D0”, this equates to 2000 mV (2V). Conversion may be required depending on the BMS data format.
⸻
Additional Notes: • This PID list is based on my current powertrain setup and may vary depending on hardware or software updates. • If you require specific BMS or motor controller data sheets, please let me know, and I can share them accordingly.

Thank you for your support. I look forward to your guidance on this matter.

PinnedHi @Mert çallı,

You can check our telemetry API for relevant properties:
documenter.getpostman.com/view/7396339/SWTK5a8w
Also, you can check our (partially outdated) OBD repository to see what other cars report:

If you find that an existing vehicle profile reads data correctly, please let us know, but please DO NOT keep using the incorrect vehicle model with live data.
