How It Works
Configure the protocol
OBD-II for cars, J1939 for trucks
Automatic reading
The module reads and stores the parameters
Data available
Query any parameter in real time
Custom Parsers (CXECU)
In addition to the automatic protocol, you can configure up to 28 custom parsers to read specific parameters not in the standard, such as manufacturer proprietary data.
Devices with ECU Module
Requires physical CAN Bus connection to the vehicle.
