SRT-E is a dedicated Engine Control Unit. A single SRT-E can drive up to eight injectors and six ignition coils. It is compatible with a wide range of sensors and actuators (especially F1 products) such as coils, injectors and sensors. SRT-E can also drive logic command coils (HW option).
Communication from the PC based configuration tool and to other units (such as dashboard and logger) is possible by 2 CAN lines and an asynchronous serial line.
Inside the unit there is a high performance RISC microcontroller and an FPGA for diagnostic purposes.
SRT-E provides analogue inputs for single-ended, differential, temperature and knock-sensor as well as an interface for a linear wide band lambda sensor. The unit also provides 2 HBridge output stages for use with suitable “Drive by Wire” or Trumpet Control actuators.
6 configurable speed sensor inputs (up to 3 inductive) provide full flexibility of configuration for engine angle detection as well as other frequency inputs such as wheel or shaft speed.
SRT-EDL is a version of the SRT E Engine Control Unit with an internal 64 Mbyte data logger.
