1. An interlock data collection and calibration system for use with an ignition interlock device, the system comprising:

  • a device computer having a computer processor and a computer memory;

    a gas delivery system for delivering a gas sample to the ignition interlock device, wherein the gas delivery system includes a cylinder of compressed alcohol sample gas, and a gas control valve operably installed on the cylinder and controlled by a microcontroller for releasing controlled samples of the compressed alcohol sample gas to the ignition interlock device;

    a data port operably connected with the device computer for enabling sample data from the ignition interlock device to be transmitted to the device computer;

    a calibration program operably installed on the computer memory of the device computer for receiving the sample data, calibrating the ignition interlock device, and generating confirmation data that the ignition interlock device was calibrated; and

    a local database operably installed on the computer memory of the device computer for storing the confirmation data;

    wherein the device computer is separate from and detachably connectable to the ignition interlock device via the data port, and wherein the device computer operatively controls the microcontroller of the gas delivery system responsive to the calibration program.
