Historical Background Before 1970 Carburetor & Distributors 1980s till now ECU Then we came New generation ECU

Motivation Nowadays: Most ECU’s today aren’t modifiable Expensive, Narrow Range Our Design: Engine modes: sport, economic, power More engines, more modes, more control

Project goals Building an Engine-Control-Unit, for power optimization of the engine performance. The unit controls the plugs and fuel injectors

specifications Real time system Read sensors with A to D Analyze and calculate using LUT’s Generate output with D to A
