Juice Box 2 is an open-source full engine management ECU designed around the Speeduino project.
Taking the development of the Juice Box to the next level, I designed this fully-fledged Engine Management ECU to convert my Triumph Spitfire to fuel injection. With robustness as the primary aim, Juice Box 2 features a robust design and a fully sealed enclosure to protect it from the harsh automotive environment. See the wiki for more details.
