Constant vibration loosens engine parts just enough to affect performance. Parts become worn from friction and don’t fit quite as tightly. It’s built to last, but after a while, it just doesn’t work like the day your car rolled off the assembly line. You end up wasting less fuel and less money. The ECM automatically reduces the engine’s power output by decreasing the amount of fuel injected. When combustion occurs at just the right moment, your pistons work the hardest-and only then will your engine produce the most horsepower!Ĭontrols Engine Idle Speed: Less engine power is needed while your car idles. However, sometimes spark plug timing can be a little off. When the optimum ratio is reached, complete combustion occurs and the engine creates maximum power.Ĭorrects Ignition Timing: For the engine to create maximum power, the spark plugs must fire at just the right moment. It automatically injects enough fuel to produce the optimum ratio of air to fuel. Optimizes the Air to Fuel Ratio: The ECM constantly measures the mixture of air and fuel inside the piston cylinders during combustion. Here are just a few of the important things your ECM does: It’s the on-board computer that controls literally everything your engine does. The ECM is the brains behind your car’s brawn. Your engine not only drives your car, but provides power to every other vehicle subsystem. What Does an Engine Control Module (ECM) Do?
