1. A motorized-vehicle information system for accessing and manipulating information relating to motorized vehicles, the information system comprising:
- a computer, comprising a user input interface capable of receiving instructions and values from a user, a microprocessor, coupled to the user input interface, the microprocessor for executing instructions and for creating a first video signal, and an output interface coupled to the microprocessor, the output interface capable of receiving the first video signal and of providing a perceivable output to a user; and
a monitoring system, coupled to a motorized vehicle and the computer, the monitoring system comprising a data acquisition system for monitoring attributes of the motorized vehicle and for providing attribute signals to a version of a monitored attribute, and a video waveform generation system for converting the attribute signals into a second video signal representing a waveform, the second video signal capable of appearing in combination with the first video signal as a real-time perceivable output at the computer'"'"'s output interface.

Abstract
An engine analyzer senses the electrical signals of a combustion engine and displays a representation of the signals on a display that is shared with a separately operable computer platform. The representation of the signals is digital and is in real-time. The display of the signals does not affect the computational burden on the separately operable computer.
