The engine speed sensor provides the ECM with a crankshaft position signal. The ECM uses the signal to determine a crankshaft reference point (Top Dead Center) and calculate engine speed (RPM.) The signal is also used by the On-Board Diagnostic system for misfire detection. The ignition system will not operate if the ECM does not receive an engine speed sensor input.
By reprogramming the engine ECM.
The ECM reads the TPS, the O2 sensor, the engine coolant temp., the ambient air temp., barometric pressure, engine RPM, road speed, and will calculate the air volume consumed by the engine. Depending on what the programed algorithms in the ECM say, the ECM will pulse the injectors a set amount of time.
The speed controls are programmed into the engine ECM. The only way to disable them is to have the ECM settings adjusted.

It's used in reference to the Electronic Control Module (ECM), which is a computer.
The speed controls are programmed into the engine ECM. If it's not your truck to do this with, the ECM is probably password protected.
The injector pulse would be different the sensor readings would be different so engine would never run smooth IF even started.
