A single chip radio transceiver includes circuitry that enables received wideband RF signals to be down-converted to baseband frequencies and baseband signals to be up-converted to wideband RF signals prior to transmission without requiring conversion to an intermediate frequency. One or more engine parameters, such as EGR, VCT, boost, throttle position, are coordinated with the direct injection to reduce torque and EGR transients. In one embodiment, a web server provides content to a client system which includes commands that, when executed, cause the input mechanism to be automatically populated with a quantity value upon receiving the user’s selection indication.
