The use of an electronic system to regulate the injection system is a solution that can improve the performance and fuel efficiency of an engine. However, conventional vehicles require retrofit to be able to use the electronic fuel injection (EFI) system. The design uses a microcontroller system with ARM32 architecture. The inputs used to determine the duration and timing of the injection are a crankshaft position sensor (CKP), throttle position sensor (TPS), manifold absolute pressure (MAP), air temperature sensor (ATS), and lambda sensor. Before the sensor signal enters the microcontroller, the signal is filtered using a low pass filter (LPF) with a cut-off point of 50Hz. The actuator system consists of an injector. While the ignition system can use a capacitor discharge ignition (CDI). The novelty in this design is that the type of sensor can be replaced with a resistant type sensor. So that there will be many variants of the fuel injection system tuning retrofit that can be done with conventional motors.
