The wide varieties of passenger cars which exist today globally address a range of legislations and buyers preferences unique to different markets. These requirements would be impossible to meet without the electronics that manage everything from ignition and fuel delivery to every aspect of emissions control. A single platform solution of Engine management system (EMS) which addresses the functional requirements of all engine types makes it difficult to reach cost sensitive segments and markets. An engine management system has been developed for the emerging market considering low cost and reduced time to market. A product line approach has been implemented for this development to reuse product components and apply variability. The emerging markets require a number of strategies for reducing the overall system cost, some of which are also addressed in this paper.

In motorcycles, Engine Management systems (EMS) are used mostly in high end models. However, increasing demands for improved fuel efficiency and tighter legislations for reduced emissions have made it inevitable to adopt EMS, instead of the carburetors even in small gasoline engines motorcycles which are already quite fuel-efficient. Today's system cost is significantly high and comparable with passenger car applications and success in emerging markets due to fun-to-drive aspects is likely to be limited to premium segment. So there is an obvious requirement for minimized system cost along with smart system solutions. For reducing the number of sensors and cost, highly accurate methods have been developed to eliminate sensors like barometric sensor and cam timing sensor. An engine management system has been developed for the unique problems of one cylinder, high performance engines.
