The Engine Control Unit
The ECU is responsible for ensuring that the engine in your Jaguar is running at its optimal performance.
There are a huge number of sensors in your car engine which are critical in reporting how your engine is running as they feed information back to the ECU which in turn makes adjustments.
One variable controlled by the ECU is the Air/Fuel Ratio.
Every engine needs oxygen to works as they work by combustion. Therefore it is essential that the correct amount of air gets into the engine when it needs it. This is also true of fuel injection, if the engine requires more fuel at a higher rate then the rate in which fuel is delivered needs to be higher. This is where the ECU comes into play. When you accelerate, the ECU will deliver a higher amount of fuel and air into the engine.
