An ML engine controller trained in simulation for a motocross engine, designed to run as firmware on an STM32H743 at the deterministic microcontroller layer, beneath any higher-level controller.

## What it is

KeiMXecu is trained in simulation to control a motocross engine and is designed to run as firmware on an STM32H743, at the deterministic microcontroller layer. A higher-level controller would speak to it through a narrow, well-defined interface and never touch the inner real-time loop directly. It is not meant to drive ignition on a real engine before dyno data exists.

## 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 is designed to separate the concerns at the silicon boundary.
