Reads the engine's sensors and controls fuelling, timing and the protection shutdowns so the engine runs to its programmed rating.

⚠️ Common Signs of Failure

• Engine will not start, or cuts out, with nothing wrong at the fuel side

• Instruments dropping out or reading erratically
• Engine held in reduced power with no obvious cause
• Corrosion or water tracking in the unit's connectors

🛠️ Service Notes

• Only 26 grams separate this unit from the 1.146 kg units in the same group, so weight is not a safe way to identify it
• Control units are matched to the engine's build and rating, so order against the engine designation
• Isolate the batteries before unplugging it, and check the harness and earths before condemning the unit
