A system for controllably sensing, recording, and selectively displaying data associated with operational characteristics of a vehicle is described. A plurality of transducers are connected to a programmable logic device along with data entry, data storage, and data display devices. Information received from the transducers is processed by the logic device to determine whether a certain operational characteristic has occurred during the time that certain other characteristics are present. In addition, the amount of time that the particular characteristic occurs is determined.

A method for controllably sensing, recording, and selectively displaying data associated with operational characteristics of a vehicle and associated engine having a plurality of transducers respectively connectable to a programmable logic device and adapted to produce parameter signals in response

A method for controllably sensing, recording, and selectively displaying data associated with operational characteristics of a vehicle and associated engine having a plurality of transducers respectively connectable to a programmable logic device and adapted to produce parameter signals in response to respective preselected engine and vehicle parameters, and having a storage device connected to said programmable logic device and data entry and display devices connectable to said programmable logic device, comprising the steps of: controllably manipulating said parameter signals to produce responsive information signals; accumulating the amount of time a preselected one of said information signals occurs during a period defined by at least a preselected one of said remaining information signals having a predetermined value; delivering said accumulated time value to said storage device; and, controllably delivering said accumulated time value to said display device.
