HYDRA ECU
Compatibility
Configuration
The ECU must be configured to output data with the standard checksum at a baud rate of 19200.
Connections
This ECU utilises standard RS232 (serial) connections:
If using a Race Technology ECU Serial Interface, connect the 'ECU' labelled connector directly to the ECU.
If using a product with a built-in interface, use the below image to connect the product to the ECU:
