ABSTRACT:
A high performance tachometer for use in high performance racing vehicles, such as dragsters, is disclosed. The tachometer has an input signal indicative of the vehicular engine speed and an output display for displaying the instantaneous engine speed as indicated by the input signal. The tachometer includes input controls for directing the control and operation of the tachometer. Special features associated with the tachometer include a memory device configured to store the value of the input signal at periodic and discrete time intervals, as directed by the input controls; a special event detector configured to detect a certain predetermined event or pattern of the input signal as determined by monitoring the output of the memory device, the special event detector being further configured to halt or freeze the output display (both deflection needle and digital readout) upon detection of the predetermined event or pattern output from the memory device; a multi-stage RPM switch is included to operatively control a plurality of controlled devices. The system is designed to allow the user to program the RPM switch to operate the controlled devices at a plurality of engine speeds. In addition, an automatic starting feature is provided. The automatic starting feature of a preferred embodiment is initiated in connection with the activation of the Line-Loc switch.
