1. A method of updating an engine control unit (ECU) of a vehicle connected to a network, the network including a local device that is electrically connected to the ECU, a client device connected to the local device, and a server connected to the client device, the method comprising:

  • establishing a data connection between the local device and the ECU using a diagnostic port;

    establishing a wireless network connection between the local device and the client device;

    generating, by the client device, a first vehicle data request;

    receiving, at the local device, the first vehicle data request;

    retrieving, by the local device, first vehicle data from the ECU based on the first vehicle data request;

    transmitting, by the local device, the first vehicle data to the client device;

    generating, by the client device, a second vehicle data request;

    receiving, at the local device, the second vehicle data request;

    retrieving, by the local device, second vehicle data from the ECU based on the second vehicle data request;

    wherein the second vehicle data includes at least one parameter for the ECU;

    transmitting, by the local device, the second vehicle data to the client device;

    transmitting, by the client device, a request for updated firmware, to the server;

    receiving, at the client device, updated firmware from the server including a list of a plurality of sets of preconfigured parameters for the ECU;

    displaying, at the client device, the list of the plurality of sets of preconfigured parameters for the ECU;

    making, at the client device, a selection of a set of preconfigured parameters for the ECU from the list of the plurality of sets of preconfigured parameters for the ECU;

    receiving, at the local device, the updated firmware from the client device including the selected set of preconfigured parameters for the ECU; and

    ,loading, from the local device, the updated firmware onto the ECU, wherein loading the updated firmware reconfigures at least one parameter for the ECU and the second vehicle data.
