Understanding The Check Engine Light

Car Engine Control SystemWhen the light comes on, a single or additional diagnostic difficulty codes (DTC) are stored in the engine control module. This produces a volumetric efficiency of significantly less than 1. At times however, when you have a tuned induction/exhaust method or a forced induction program (supercharger, and so forth.), more air will enter the cylinder than it should generally hold and you get a VE greater than 1. This table is employed as a sanity check, in particular when the car is beneath high load, so that the personal computer knows how to adjust fuel and spark values to respond to anticipated cylinder pressures.

With careful intake/exhaust tuning you can get a spike in torque at a higher RPM, which will make a higher peak HP value but if the location under the torque curve is pathetic, your car or truck will always be much less strong than an additional with a flatter torque response, reporting a reduce peak HP so don’t assume you can race and beat any person whose car has significantly less advertised HP than you.

Hood Security Switch – This is an significant security function for you or the mechanic who performs on your automobile This prevents the remote car or truck starter from starting when the hood is up. You may not assume you need to have a hood security switch, but when your vehicle breaks down or runs out of gas, probabilities are the initially thing you will do is pop the hood.

The induction method is a considerable restriction in your airflow so this is where most individuals start off when they look to acquire efficiency. A fantastic remote car or truck starter can begin your car or truck from really a distance, shop about and evaluate. If car efficiency does modify, drive …
