The S8 ECU offers an extremely high level of precise engine management control.

The twin processor unit uses a high speed RISC processor for code execution and an additional large FPGA for high speed engine position tracking, allowing the scheduling of code to be independent of signal patterns, increasing flexibility, efficiency and accuracy under transient conditions. This powerful combination also allows advanced control algorithms but allowing it to be easy to map for the end user.
