2130914 9320345 PCTABS00027 A control system (140) for an internal combustion engine (100) having a plurality of cylinders (C1-Cn) and a rotatable crankshaft (110). Each cylinder (C1-Cn) has an electronically actuatable intake valve, exhaust valve (120, 125) and fuel injector (130). The control system includes a sensor (155) which monitors the rotation of the crankshaft (110) and responsively produces a crankshaft pulsetrain. A computer (216) produces operator parameter signals. The operator parameter signals including one of a plurality of operating modes of the engine (100). A first microprocessor (226) receives the crankshaft pulsetrain, responsively determines the speed of the engine (100) and produces a signal representative of the determined engine speed. A second microprocessor (222) receives the operator parameter signals and the engine speed signal, responsively determines valve and injection events for each cylinder (C1-Cn) to responsively achieve the one engine operating mode. The second microprocessor (222) produces signals representative of the determined valve and injection events.
