A method and control apparatus for an internal combustion engine that allows an operator to calibrate engine performance relative to an engine operating characteristic. The control apparatus comprises a base engine control map that correlates values of the characteristic with values of a base engine
A method and control apparatus for an internal combustion engine that allows an operator to calibrate engine performance relative to an engine operating characteristic. The control apparatus comprises a base engine control map that correlates values of the characteristic with values of a base engine control, a trim control map that correlates the values of the characteristic with values of a trim control, an engine control unit that obtains from the base engine control and trim control maps the respective base engine control and trim control values that are based on the characteristic value, and a panel that is operatively coupled with the engine control unit and includes a first switch regulating a trim signal supplied to the engine control unit. The trim control map is separated from the base control map. The engine control unit calculates an engine operating control value based on the obtained values. The calculated engine operating control value is supplied to the internal combustion engine to vary the engine performance. The first switch is adapted to be manipulated by the operator. And the trim signal causes the engine control unit to modify the trim control values in the trim control map.

A vehicle tire monitoring system for monitoring a tire mounted on a wheel and having a tread surface for contacting a ground surface, said tire monitoring system comprising: a first sensor located on a tire and generating a first electrical signal containing information about a first tread contact length; a second sensor located on the tire and generating a second electrical signal containing information about a second tread contact length; a third sensor located on the tire and generating a third electrical signal containing information about a third contact length; and a controller for processing the first, second, and third electrical signals and determining the first tread contact length based on the first electrical signal, the second tread contact length based on the second electrical signal, and the third tread contact length based on the third electrical signal, said controller further processing the first, second, and third tread contact lengths to determine a characteristic of the monitored tire. 12. The tire monitoring system as defined in claim 11, wherein one of said first, second, and third sensors is substantially centered about a tread portion of the tire and is substantially located midway between the other two of the first, second, and third sensors. 13. The tire monitoring system as defined in claim 12, wherein said other two of the first, second, and third sensors are located near side walls of the tread portion of the tire. 14. The tire monitoring system as defined in claim 11, wherein said controller compares the first, second, and third tread contact lengths and determines a tire inflation characteristic. 15. The tire monitoring system as defined in claim 11, wherein said controller determines a tire-to-ground surface camber. 16. The tire monitoring system as defined in claim 11, wherein said controller determines a slip angle of the tire. 17. The tire monitoring system as defined in claim 11, wherein said controller determines a contact patch area as a function of the first, second, and third tread contact lengths. 18. The tire monitoring system as defined in claim 11, wherein the first, second, and third tread contact lengths are determined based on first, second, and third measured time periods, respectively. 19. The tire monitoring system as defined in claim 11 further comprising a transmitter for transmitting the first, second, and third electrical signals to the controller, said controller being located remote from the transmitter. 20. A method of monitoring a tire mounted on a wheel and having a tread portion for contacting a ground surface, said method comprising the steps of: sensing contact of a tread portion of a tire with the ground surface with a first sensor at a first location of a tire; sensing contact of the tread portion of the tire with the ground surface with a second sensor at a second location of the tire; generating a first electrical signal containing information about a first tread contact length; generating a second electrical signal containing information about a second tread contact length; processing the first and second electrical signals to determine the first tread contact length based on the first electrical signal and the second tread contact length based on the second electrical signal; and determining a characteristic of the monitored tire based on the first and second tread contact lengths. 21. The method as defined in claim 20 further comprising the steps of: sensing contact of the tread portion of the tire with the ground surface with a third signal located at a third location of the tire; generating a third electrical signal containing information about a third tread contact length; and processing the third electrical signal to determine the third tread contact length based on the third electrical signal, wherein said controller determines the characteristic of the monitored tire based on the first, second, and third tre ad contact lengths. 22. The method as defined in claim 21, wherein one of said first, second, and third locations is substantially centered about the tread portion of the tire and is substantially located midway between the other of the first, second, and third locations. 23. The method as defined in claim 20, wherein one of said first and second locations is substantially centered about the tread portion of the tire, and the other of the first and second locations is located nearer to a side wall of the tread portion. 24. The method as defined in claim 20 further comprising the step of determining a tire inflation characteristic as a function of the first and second tread contact lengths. 25. The method as defined in claim 20 further comprising the step of determining tire-to-ground surface camber as a function of the first and second tread contact lengths. 26. The method as defined in claim 20 further comprising the step of determining a slip angle of the tire as a function of the first and second tread contact lengths. 27. The method as defined in claim 21 further comprising the step of determining a contact patch area as a function of the first, second, and third tread contact lengths. 28. The method as defined in claim 20 further comprising the step of determining a first measured time period that the tread portion of the tire is in contact with the ground at the first location and determining the second time period that the tread portion of the tire is in contact with the ground surface at the second location, wherein the first and second tread contact lengths are determined as a function of the first and second measured time periods. pathogenic microorganisms, especially fungi.
