What it does
KeiMXecu is an engine-control-unit — sensing, ignition/fuel timing, safety interlocks — running at the deterministic MCU layer on STM32H743. A higher-level controller can speak to it through a narrow, well-defined interface, but never touches the inner real-time control loop directly.
Why a dedicated controller
Engine and powertrain control has hard real-time constraints. A general-purpose application processor sharing the loop with a planner or an ML model is a liability. KeiMXecu separates the concerns at the silicon boundary.
