2. Objectives Study the Microsquirt Project Design our own engine control unit (ECU) Design a convenient connection method Test on Harley Davidson Motorcycles – Injection & Ignition Timing – Engine Specific Sensors and Signals 2

3. What is the Microsquirt? Electronic Fuel Injection Controller – Compact – Less Driving Current – Suitable for Motorcycles or other small vehicles Programmable by End User 3

4. Custom Board Layout Layout Specifications Two layer board Separate ground planes to reduce noise –Analog (High power) –Digital (Communications) Total board side 6.3x4” 4
