https://docs.emtronaustralia.com.au/engine-management/functions/trans-brake-control/index.htmlThe Transmission Brake Function allows the ECU to directly control the Trans Brake inside the gearbox. Output The Function can be switched ON from the Config view -> Functions -> Motorsport Functions tab -> Transmission Brake Control. This menu allows the Output Channel to be selected and configured. When driving the solenoid directly from the ECU, use ONLY Auxiliary Channels 13-16. These solenoids typically require a minimum of 10A to switch. Make sure the ECU is grounding the solenoid and sufficient ECU grounds are connected to support the current. Typically a PDM would be used to supply power to the solenoid. Input Two Inputs will need to be setup under the Config View -> Inputs -> Motorsport TabHugoen-us
