In this article, I would like to show the analysis which I have done on the ECU installed on Honda CBR125R. One person from France kindly sent me for free this ECU, and I sent him a Fuelino Proto3. Before opening the ECU, it looks as in the following picture. First of all, the following … Continue reading "Keihin ECU on Honda CBR125R"
This article has the purpose to explain how Fuelino calculates the control signal which is output to the fuel injector. In order to better understand how this simple control works, I decided to create a scheme using Matlab Simulink. The signal flow goes from left to right. First of all, in order to work, Fuelino … Continue reading "How Fuelino manages electronic fuel injection"
Some weeks ago, I received at home the second prototype of PCB for the Fuelino shield (compatible with Arduino Nano r3). Since all components are "through hole mount", and there are quite many, the soldering and testing phase required about 1 h. First of all, I decided to solder the resistors (they are the components … Continue reading "Fuelino proto2 PCB mounting"
Few months ago I decided to start with this project: Fuelino. I was looking for a customized ECU (Engine Control Unit) piggyback with the purpose of adapting my motorcycle (Honda CBR125R) to the custom parts which I installed on it (Athena 166cc bore up kit, conic air filter, Akrapovic racing exhaust system, and so on). … Continue reading "Fuelino proto1 schematic and board"
Today I have the pleasure to show you my latest project: Fuelino. The name comes from "Fuel" and "Arduino". The unit is a fuel controller for single cylinder engines, and it is addressed especially to small engine motorcycles and scooter (less than 250cc). The unit gives you the opportunity to modify the fuel injection control, … Continue reading "An introduction to Fuelino project"
