Arduino Software for the Fuel Injection controller (Version 1)

In this post, you can find the downloadable version of the software to be flashed in the ECU. After creating the ECU electronic circuit for adjusting your motorcycle Fuel Injection timings, it is necessary to upload the software inside the Arduino Micro. The software which I created is composed by 2 parts: "Tempo" library. It … Continue reading "Arduino Software for the Fuel Injection controller (Version 1)"

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"

How PGM-FI Electronic Fuel Injection works

As many people already know, an engine is a system which transforms chemical energy into mechanical energy: an engine receives the energy from one or more types of fuel (for example, gasoline, in most motorcycles); this energy is transformed into mechanical energy (mechanical work at the engine shaft) and heat by mean of combustion. In … Continue reading "How PGM-FI Electronic Fuel Injection works"

Akrapovic carbon racing exhaust sound check

Yesterday I took some videos to show how the sound will change after mounting an Akrapovic carbon racing exhaust on your Honda CBR125R motorcycle. First of all, let me list up the mods that I did on my bike: Akrapovic carbon racing exhaust system Modified air filters (Daytona 45mm + Kijima 12mm) Athena bore-up kit … Continue reading "Akrapovic carbon racing exhaust sound check"
