Powertrain Control Unit

TAG-310B

The TAG-310B is the main processing unit for complete powertrain control of a racing car. It may be used with companion driver units (e.g. IGN-310 and ING-310 or PB2006) to provide direct control of ignition and injection, along with all other powertrain control functions. The TAG-310B provides a powerful processing platform with minimum latencies for customer applications based on PowerPC processors. Application code is autocoded using our Graphical Development Environment (GDE) from Matlab/Simulink control modules. The unit comes with integral data logging and high speed communications capabilities.

The TAG-310B is configured by System Monitor and the logged data is displayed and analysed by ATLAS.

For example system configurations please refer to the Application Notes.
