The XK8 engine management system and electronic engine control module

The increasing demand for feature enhancements on passenger vehicles combined with more stringent emissions and legislative requirements world-wide has lead to a high level of complexity within engine control modules, associated emission control hardware and equally important, software. This paper briefly explains how the functions of the AJV8 engine control work and how the diagnostics form an integrated part of the system design. The author covers throttle control, ignition control, and fuelling control.
