Abstract

Program instructions and/or data used in vehicle computers can be downloaded into the vehicle from a personal computer, which obtains the information from a web server. Different types of programmed modifications can be readily downloaded into a vehicle simply by downloading the appropriate program. Once the program instructions and/or data are downloaded, they can be copied into a vehicle computer using available interfaces, such as the onboard diagnostic system connector (OBD-2) available on many vehicles.

data and instructions for a computer of a vehicle, said data and instructions to be downloaded by said second processor into a computer in a motor vehicle.

13. The system of claim 12, wherein said first memory device stores computer program instructions, which when executed, cause the first processor to function as an Internet web-site server.

14. The server of claim 13, wherein said first memory device stores computer program instructions, which when executed, cause the first processor to require said second processor to provide identifying data to said first processor, prior to said first processor sending data or instructions to said second processor, said identifying data identifying a person who is authorized to receive data and instructions from said first processor.

15. The server of claim 13 wherein said first memory device stores computer program instructions, which when executed, enable the first processor to receive at least one of:

data and instructions, from an engine controller of a vehicle.

16. The server of claim 13 wherein said at least one memory device is a memory device that stores at least one of:
