Efficient telematics data upload

A system comprising:

• a processor configured to, responsive to receiving a VIN from a remote vehicle and data about an internal bandwidth of a bus of the vehicle and a transfer rate of a connection between the vehicle and processor, transmit to the vehicle a parameter definition selected based on fields of the VIN, the internal bandwidth, and the transfer rate, wherein the parameter definition is configured to prompt
• a telematics control unit of the vehicle to select an alternative channel to operate on to increase available bandwidth of the connection between the vehicle and processor, and
• an ECU of the vehicle to enter a logging mode to capture operational data of the vehicle, to decimate the operational data to generate compressed operational data and conserve the internal bandwidth of the bus of the vehicle, and send the compressed operational data to the processor via the connection between the vehicle and processor.
