Abstract

A programmable electronic ignition system is provided including a hand-held programmer, or in the alternative a computer, for controlling engine control parameters including revolutions per minutes limiters, ignition timing retards, gear shift controls and revolutions per minute switching. The hand-held programmer or computer provides a menu driven interface which directs the user through the engine control parameters using easy to recognize terms. The programmable electronic ignition system can employ a cylinder location sensor to identify a predetermined cylinder for controlling individual cylinder ignition timing retards.

Claims

1. A method for allowing a user to adjust predetermined engine operational parameters via an electronic engine controller, the method comprising:

providing a data directory comprising data structures for facilitating an interface with one or more devices that allow a user to communicate with the electronic engine controller via the data structures;

arranging related engine operational parameters in the data structures according to predetermined groups;

associating indicia descriptive of the groupings of engine operational parameters with the data structures of the data directory;

providing a display device that allows a user to view the descriptive indicia corresponding to the different predetermined groups of related engine operational parameters from the data structures in one of a first mode or a second mode of operation allowing retrieval with the information processor of information from the data structures including descriptive indicia and operational data in the first mode of operation while providing access to the operational data in the second mode of operation independent of the descriptive indicia;

identifying the data structures for viewing the descriptive indicia corresponding to the group of engine operational parameters desired to be adjusted; and

making the engine operational parameters accessible for identified engine operational parameters and corresponding descriptive indicia to tailor performance to the user'"'"'s preference.

2. The method of claim 1 wherein the display device comprises a compact hand-held programmer with inputs operable by the user holding the programmer in the user'"'"'s hands.

3. The method of claim 1 wherein the display device comprises a computer with an input keyboard operated with the computer resting on a support surface.

4. The method of claim 1 wherein descriptive indicia are English or foreign language words so that the user views and reads English or foreign language words on the display to allow the user to readily determine the nature of the engine operational parameters to be adjusted in any one of the predetermined groups.

5. The method of claim 1 wherein the predetermined groups include a set of maximum revolutions per minute controls, and

the inputs are operated by a racer to adjust the maximum revolutions per minute values during different stages of a drag race.

6. The method of claim 1 wherein the predetermined groups include a set of ignition timing controls, and

the inputs are operated to adjust the predetermined degrees of ignition timing coordinated with the settings made to at least one of the other predetermined groups of engine operational parameters.

7. The method of claim 6 wherein at least one other predetermined group is one of gearshift controls, revolutions per minute values, the revolutions per minute during the starting mode of an engine, a time duration, and cylinders.

8. The method of claim 1 wherein the predetermined groups include:

a set of individual cylinder ignition timing retard controls, a set of gear shift controls,

a revolutions per minute switch, or a magnetic pickup compensation.

9. A user interface device for allowing manual adjustments of engine operational parameters via an electronic engine controller, the user interface comprising:

a housing;

a memory device;

a screen for displaying indicia conveying the engine operational parameters to the user;

an information processor programmed to generate the indicia for storage in said memory device as being descriptive of different groups of engine operational parameters that can be adjusted and readily interpreted by the user as associated with a specific one of the operational parameters;

a data directory comprising data structures in said memory device provided for facilitating an interface in a first mode of operation allowing users to communicate with said information processor via the data structures;

wherein said data directory facilitates an interface in a second mode of operation for communication with a personal computer which retrieved data from said data structure for display to users on a video display unit of the personal computer;

key inputs to change the descriptive indicia on the display to the desired group of engine operational parameters to be adjusted without need to reference other materials to interpret the indicia; and

a communications link allowing the key inputs to control the operation of the electronic engine controller to make the desired performance adjustments.

10. The user interface device of claim 9 wherein the housing has small predetermined dimensions for being hand-held.

11. The user interface device of claim 9 wherein the housing is for a personal computer including a pointing device attached thereto.

12. A method for allowing a user to adjust predetermined engine operational parameters, comprising:

providing an electronic engine controller that accommodates a plurality of devices for user communication via a data directory comprising data structures for interfacing with the electronic engine controller;

arranging related engine operational parameters in the data structures according to predetermined groups;

associating descriptive indicia and operational data of the engine operational parameters in the data structures;

obtaining information from the data structures in one of a first mode or a second mode of operation allowing retrieval with the information processor of information from the data structures including descriptive indicia and operational data in the first mode of operation while providing access to the operational data in the second mode of operation independent of the descriptive indicia; and

making the engine operational parameters accessible in the first mode and second mode of operations for modifying the engine operational parameters to tailor performance to the user'"'"'s preference.

13. The method of claim 12 comprising identifying the data structures in the first mode of operation for viewing the descriptive indicia according to the group of engine operational parameters desired to be adjusted.

14. The method of claim 12 comprising identifying the data structures in the second mode of operation for accessing the operational data corresponding to the group of engine operational parameters desired to be adjusted.

15. The method of claim 14 comprising providing an external computer in the second mode of operation for communication and display of retrieved data from said data structure with the descriptive indicia being provided by the external computer.
