A portable cover unit includes a fabric cover supported by a flexible frame. The fabric cover has sleeves that secure members of the flexible frame, which is constructed with primary frame members extending in a first direction and at least one secondary frame member extending in a second substantially perpendicular direction between the primary frame members. A plurality of connectors are attachable to an object to which the portable cover unit is installed, each including an aperture sized to receive the primary frame members. Structure is also provided for securing the fabric cover to the object to which the portable cover unit is installed. The portable cover unit can be mounted to any open portion of a vehicle such as a boat, golf cart or the like or can be used independently. The structure can be readily disassembled and stored in a compact package.

The system of claim 12 wherein the control computer is configured to control the actuator control signal to allow exhaust flow through the EGR conduit if the EGR valve position signal indicates that the EGR valve is closed and the EGR cooler condensation state indicates that condensation would not be occurring if the EGR valve was otherwise positioned to allow engine exhaust flow through the EGR conduit.15. The system of claim 12 further including:an ambient temperature sensor producing an ambient temperature signal indicative of ambient temperature;an ambient pressure sensor producing an ambient pressure signal indicative of ambient pressure;an ambient relative humidity sensor producing an ambient relative humidity signal indicative of ambient relative humidity; andan intake manifold pressure sensor producing an intake manifold pressure signal indicative of pressure within the intake manifold;and wherein the control computer is configured to determine the amount of water present in the engine exhaust flowing through the EGR conduit as a function of the ambient temperature signal, the ambient pressure signal, the ambient relative humidity signal, the intake manifold pressure signal and an amount of water resulting from combustion of fuel in the engine.16. The system of claim 15 wherein the control computer is configured to determine an amount of water present in fresh air en
