Fuelino system layout and connection pins

The picture below shows the system layout of Fuelino "proto1". In its most simple configuration, Fuelino requires only 4 pins connections: Battery voltage (12V). Positive pole of the injector. Ground (0V). Vehicle chassis metallic frame. Injector command from original ECU. The original ECU has a transistor which controls the status of this pin: when the … Continue reading "Fuelino system layout and connection pins"

Since I also modified some parameters of the ECU software, I first had to flash it on the Arduino Micro. In contrast with the data logger, … Continue reading "Engine speed, injection time and throttle position visualization"
