I waited for this moment for a long time. After designing, manufacturing, soldering and mounting the Fuelino Proto3 board, today I finally tested on my motorcycle (Honda CBR125R).
At first, let me introduce this board very quickly. Fuelino project was born just 3 months ago. I was trying to design a piggyback ECU, which can be mounted on 1/2 cylinder motorcycles, capable of customizing the fuel injection command, and also acquiring (logging) data on a Micro SD card. This is the result. I fixed the board, which is just 5cm x 5cm, into a plastic enclosure, and manually made the wiring harness to connect it on my Honda CBR125R.
- One connector (2 pins) comes from the original ECU, and it has "+12V" and "injector command signal".
- One connector (2 pins) comes from the original injector, and it has "+" and "-". The "+" should be connected to "12V", and the "-" should be connected to the command coming out from Fuelino.
- One connector (1 pin) coming from the chassis (it corresponds to Ground, 0V).
- One connector (1 pin) for Throttle signal.
Finally, the next video shows the behavior of Fuelino Proto3 in "engine idling" conditions, about 2000rpm (the engine was cold). I am sorry, the video is very short, and since there are many houses around here, I could not run the engine for a long time. In the next days, I will update more videos, including data logs obtained with the Micro SD card.
