This study aims to optimize fuel consumption in the Garuda UNY Urban Gasoline-19 vehicle by changing the injection time mapping. Injection Timing Mapping using Programmable ECU software MegaSquirt III and Tuner Studio 3. Based on standard ECU data, Mapping Timing Injection Case 1 (IT-C1) and Timing Injection Case 2 (IT-C2) were generated. Performance tests are carried out using static tests in the laboratory and dynamic tests in the field. The application of IT-C2 resulted in the best reduction in fuel consumption, namely 12% in the static test and 11.08% in the dynamic test. The delay in initiation of injection results in less responsive acceleration. © 2020 Institute of Physics Publishing. All rights reserved.
