Hi, I wanted for some time make my bike a little bit more powerful by adding a piggyback ecu. They are quite expensive so I want to make my own as some people had before. What Im working with is an arduino uno and a efi single cylinder 125cc so has anyone some idea of how to do it? I would like to use the oes injector timing and just add onto it. It would also need to use the throttle position, wich is easy enough to get and the rpm to know how much fuel to add. So like some tables with values to change and adjust maybe: RPM, Throttle position in % and time added. Thanks for any helper.
