Abstract
An electronic means for monitoring and controlling engine performance. The device takes input signals from vehicle engine speed sensor and ignition values. The electronic means is capable of recording an RPM event, and playing it back on the existing vehicle tachometer. Either the entire RPM event may be replayed, or the highest RPM value achieved during the event. Furthermore, the electronic means comprises a dial to set the RPM limit of an engine to prevent over-revving. Once the engine reaches the maximum user-defined RPM value, the electronic means interrupts the ignition system to prevent the engine from revving above such pre-determined value. The electronic means further comprises a shift light which illuminates once an engine reaches a pre-determined RPM value in order to alert the driver to shift gears.
