Motorsport TAG Control

Electronic Control Unit TAG-320B

TAG-320B is the main processing unit for powertrain control of a racing car. It may be used with an external driver unit to provide direct control of ignition and direct or manifold injection, along with all other powertrain control functions. The TAG-320B provides a powerful processing platform with minimum latencies for customer applications based on 32-bit microprocessors. Application code is autocoded from Matlab/Simulink control modules. Advanced data logging, high-speed telemetry control and rich communications are all provided. The TAG-320B is built with full FIA security measures including advanced memory protection and supports applications already running on the TAG-320 and TAG-310B.
