Topic: Fuelino for Arduino Nano - motorcycle Fuel Injection control and data logger (Read 10347 times) previous topic - next topic


I would like to share with you the project for which I am working in the free time: the name is Fuelino.

Fuelino is a fuel injection controller and data logger designed for motorcycles equipped with EFI (Electronic Fuel Injection). By regulating the fuel injected in the cylinder, it is possible to increase the power of the engine. Even if this modification is optional, if you have a stock engine, it becomes mandatory if you change some components of your motorcycle, such as exhaust pipe, camshaft, cylinder size (bore up kit), air filter and so on.
Fuelino helps to adjust the injection timing, to achieve the proper stoichiometric air-fuel ratio which maximizes the output power of the engine, or minimizes fuel consumption. The compensation applied to the original signal timing, in %, depends on the throttle position sensor signal (if connected), and the engine rotation speed (calculated from the measured time period between 2 consecutive "start of injection" events).

The project is completely open source, you can find more info at the following links:



The following image shows how to connect it to the motorcycle (schematic example refers to Honda CBR125R). The connection scheme is general, and can be applied to any 1/2 cylinders engine equipped with Electronic Fuel Injection.
