Direct injection technology in 2-stroke motorcycle engines can be a hope for overcoming exhaust emissions and optimizing ignition 2-stroke engine performance because direct injection engines use high-pressure pumps based on injection time and duration. On the TPS (throttle position sensor) to produce the optimal fuel mixture. This research will focus on Remapping the Arduino Uno-Based Electronic Control Unit (ECU) Module to Analyze Optimal Engine Rotation Speed in Spark Ignition 2-Stroke Direct Injection Machines. Experimental method using a Spark Ignition 2-Stroke Direct Injection engine with a capacity of 110cc. Variation of injection time angle 5°, 10°, and 15° Before BDC, 0° BDC, and 5°, 10°, and 15° after BDC, variations in injection duration based on TPS opening 20%, 40%, 60%, 80%, and 100%, as well as the fuel injected duration of 3ms, 3.25ms, 3.5ms, 3.75ms and, 4.25ms. Arduino module as a control system for timing and duration of fuel injection. Then tested alternately to get the optimal engine speed using a tachometer. Optimal results are obtained on the injection time curve 15 before BDC produces optimal engine speed with a value of 5480 rpm with a duration of 3.75 ms based on TPS openings of 61-80%. © Published under licence by IOP Publishing Ltd.
