ABSTRACT:
A control system and method for an internal combustion engine that employs a throttle position sensor and an engine speed sensor. The initial fuel air ratio control is based upon a map experimentally determined from throttle position and engine speed settings for optimum performance. However, in the event the throttle position sensor is deemed to be inaccurate, then another method is utilized for engine control purposes. In most embodiments, a map is also used in the other way.
