                                              Repeated reference will be made to the table lookup function in later
                                         chapters. In particular, Chapter 7 will discuss how a typical digital engine
                                         control system frequently obtains data using table lookup.
                                              After a chapter on basics of automotive engine control and a chapter on
                                         sensors and actuators, this book will deal more specifically with particular
                                         microcomputer automotive instrumentation and control systems to show how
                                         these systems are used in the automobile to control the engine and drivetrain
                                         and many auxiliary functions.
