Tuners and researchers have searched for ways to pull data from cars and modify it ever since the introduction of the first on-board computer in the late 1960s. The advent of fuel injection and computer-controlled engines in the 1990s brought computerized tuning front and center. And while the OBD2 standard — made mandatory in 1996 —standardized the interface and made it easier to read diagnostics and log some parameters, modification and advanced logging was still complicated and expensive.

Professional tools and open source hardware popped up in the past decade to allow deeper access into a car’s electronics, but most ready-made products were still expensive. Open source variants also required knowledge of soldering and programming. Now, Macchina has taken the best of both worlds and packaged it into an inexpensive product that should prove useful for researchers as well as tuners.
