Abstract
A vehicle electronic control system includes a processor, a reprogrammable memory, and a wireless receiver. The reprogrammable memory includes an EEPROM, flash non-volatile memory, and/or other memory which can be reprogrammed to remotely upgrade instruction sets, such as configuration data, operational instructions, or the like which control vehicle performance. These upgrades are remotely achieved by wirelessly transmitting an updated instruction set to the reprogrammable memory through the receiver. The updated instruction set replaces the previous instruction set currently programmed in the reprogrammable memory, such that vehicle performance is improved.
