Fuelino Proto3 wiring diagram

In this article, I will explain how to connect a Fuelino Proto3 to your motorcycle. 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, you can increase the power of your engine. Even if this modification is optional, … Continue reading "Fuelino Proto3 wiring diagram"

Fuelino fuel injection increment validation

As I already explained in the previous posts, basically Fuelino increments the fuel injection time by a specific period (defined in %), based on how the calibration maps are set (using the calibration tool). In particular, the maps are 2: one map defines the increment (%) depending on the engine rotation speed (rpm); the other … Continue reading "Fuelino fuel injection increment validation"

Fuelino SW validation using Pico DrDaq and VisualStudio

This article shows how I am performing one part of Fuelino software validation. First of all, why is software validation necessary? The main reason is to verify that no software bug is present, and the second one is to make sure that the software behavior, in term of injection management, is according to the theory. … Continue reading "Fuelino SW validation using Pico DrDaq and VisualStudio"

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"

Custom ECU for Fuel Injection regulation: schematics and layout

Today I would like to share with you the schematics of the DIY ECU which I built for my Honda CBR125R. This additional ECU does not have the purpose of substituting completely the original Honda (Keihin) one; it is an ECU which works, in series with the original one, to manage the signal of the … Continue reading "Custom ECU for Fuel Injection regulation: schematics and layout"
