ABSTRACT:
A system for converting a signal from a substantially linear transducer detecting a parameter on a motor vehicle electronic fuel injection system, and so enabling parameter acquisition to varying degrees of accuracy; wherein the transducer is a potentiometer for detecting the setting of the throttle regulating air intake by the engine; and wherein the conversion system itself comprises an electronic circuit featuring at least one amplifier for supplying at least one signal differing in slope as compared to that supplied by the transducer; and a processing unit for enabling parameter acquisition to a degree of accuracy depending on the modified slope of the signal supplied by the aforementioned electronic means.
