DESCRIPTION

Designed as the latest evolution in the series of SRG control units, the SRG-340 EVO introduces multi-core functionality for an increased computational power. The unit can drive up to 4 Peak & Hold GDI injectors, a High Pressure Pump with 8 A peak current and 5 A hold current and up to 4 ignition coils, including logic command coils (SW option). The Actuation core, based on a high performance PowerPC microcontroller and an FPGA for diagnostic purposes, manages injection, ignition and general power
output. The data logger and communication processor is an ARM 32 bit Cortex with a flash disk up to 1 GByte. The communication with other units, such as dashboards and loggers or from the PC-based configuration tool, made through 3 CAN lines, a 100 Mbit/s Ethernet line and a full-speed USB 2.0. The unit provides analogue inputs for single-ended, temperature and knock-sensors and an interface for a switching lambda sensor. The unit also provides Half-Bridge output stages for use with suitable “Drive by Wire” actuators. Up to 10 configurable speed sensor inputs (Inductive, Rate or Hall), provide full flexibility of configuration for engine-angle detection and other frequency inputs, such as wheel or shaft speed.
