An engine system incorporating an intake manifold, a compressor, and a controller. The compressor may provide air to the intake manifold and the controller may be connected to the intake manifold and the compressor. The controller may receive a control signal and control air flow from the compressor to the intake manifold based on the received control signal. The controller may control the air flow from the compressor to the intake manifold based on a first equation when a value related to the control signal is on a first side of a threshold and according to a second equation when the value is on a second side of the threshold. The controller may control the air flow between the compressor and intake manifold according to the second equation to prevent the compressor from operating at a surge condition when controlling the air flow according to the first equation.

Methods, systems, and products monitor environmental conditions in an enclosed environment, such as a garage or storage shed. If a dangerous environmental condition is determined, such as elevated carbon monoxide, an entry door may be opened. If further remedial measures are required, ignition of an internal combustion engine may be prohibited.
