Well, it first monitors the CPS to establish the approximate timing of the engine when the starter has turned it 2 revolutions. If it decides that the timing parameters are correct at this point, it enables the fuel pump and proceeds to fire the injectors and spark plugs. Once the engine is running, it then also monitors the Camshaft Position Sensor to establish the exact engine timing, from which it decides to advance or retard depending on engine demands.

So, you would be telling the engine to run WITHOUT specific control.

Your engine, your choice.
