1. A system for monitoring an engine comprising a plurality of cylinders, the system comprising:
a plurality of sensors each coupled to one of the cylinders of the engine and configured to detect a peak firing pressure from each cylinder, wherein the plurality of sensors are each configured for coupling to a blowdown valve associated with one of the cylinders of the engine;
a controller coupled to the sensors and configured to calculate an average of the peak firing pressures of the cylinders and determine a condition of the engine based at least in part on said average; and
a monitor coupled to the controller for displaying the pressure data.
