ABSTRACT:
A system for testing an automotive engine management system (EMS), comprises (a) means for generating a series of EMS input signals which are equivalent to input signals generated by an automobile; (b) means for applying the EMS input signals to the EMS in a manner which simulates that of the inputs from an automobile; (c) a series of loads connected to outputs from the EMS, the loads being equivalent to the loads imposed by systems within an automobile under the control of the EMS; (d) sensors for measuring the EMS outputs; and (e) means for coordinating, in real time, application of the EMS inputs and measurement of the EMS outputs.
