MBE ECUs
MBE 967
The MBE 967 serial – Race Technology interface connects between the ECU and either a data logger or a dashboard enabling monitoring of all the data channels.
NOTE: Due to the non-standard pinout of this ECU an adapter cable is required, contact Race Technology.
The output of the ECU must be enabled for continuous operation on the serial port. Please refer to your ECU documentation for instructions on how to do this.
For the output of the MBE ECU to be decoded correctly, the 16 channel output from the ECU must be set up to send the following data, which will appear on the following channels.
The ECU should be set up with following configuration:
