Historically, stand-alones are seen as expensive and hard to understand and tune. Most of all stand-alones have the reputation of being a nightmare to wire, often requiring custom harnesses and additional sensors. Their capacities and complexity usually make them best suited for race cars. However, the leading-edge technology and high specific output of many of today's import street cars need this level of control to keep the power flowing reliably. Many companies are making the transition from piggy back systems to standalone systems simple.
There are several different configurations and manufacturer's of standalone engine management systems. To properly select one you'll need to know what you'll be doing with it, future upgrades, data acquisition needs and budget.
