The Modular Engine Management System, or MEMS, is an electronic control system used on engines in passenger cars built by Rover Group in the 1990s. As its name implies, it was adaptable for a variety of engine management demands, including electronically controlled carburetion as well as single- and multi-point fuel injection (both with and without electronic ignition control). The abbreviations "SPi" and "MPi" refer to the single-point and multi-point injection configurations, respectively.[1]
In 1985, Rover Group made the decision to develop a new electronic engine management system in-house, and from its inception, the system was intended to be flexible enough for use with future engine designs. It was also intended to improve quality and reliability and to consume less power and occupy less underbonnet space than previous engine management systems.[2] The system first became available in 1989, when it was fitted to the Austin Montego 2.0L. Over the next seven years, the system appeared on cars across Rover's model lineup, including the Mk VI and Mk VII Mini and the MG F / MG TF. It was also paired with Rover engines used by other marques, such as the Lotus Elise and several Caterham models using the Rover K-series engine.[3]
