The diesel performance industry including tuners, modules, and programmers can significantly unleash the optimum performance and fuel efficiency of modern diesel-powered vehicles. Devices used in performance tuning are simply known as “chips” involving different operating parameters such as fueling characteristics and timing, for optimum power output, increased performance, fuel efficiency, and additional features like modification and reprogramming features for engine factory calibration. The ECM refers to a computer, featuring many of the same parts of a computer you have at work and at home. The ECM programming device has a microprocessor that receives, interprets, and reacts to input sensors as quickly as they occur, consisting of hardware (standard circuit board) which is encoded with a software program (tells the vehicle how to run).
Every car has an ECM system, but it is not really an important factor when making a decision between different models. The exception to the rule are modified cars which need to run using a programmable ECM. Regardless of your car model and ECM, the inputs are pretty much the same in each system. The ECM system is used in monitoring and regulating the throttle position sensor, telling the engine how much air and fuel to mix to make power; the coolant temperature sensor, letting the engine know if it is running too hot (alerts the driver, with the use of the instrument panel light); the voltage regulator, for tracking and adjusting how much power is being sent throughout the car; the fuel injectors, providing fuel at precisely the right moment for optimum power delivery; the position sensors for the camshaft and crankshaft, identifying the engine’s cycles; the mass airflow sensor and MAP (manifold absolute pressure) sensor, for monitoring the different ways air affects the engine; the oxygen sensor, measuring exhaust quality; idle control; the EGR valve sensor, helping with emissions and the ignition control, regulating the spark plugs.
The ECM systems are sourced and customized and they are not really designed by automobile manufacturers. There are only a handful of OEMs or Original Equipment Manufacturers make ECM systems for cars. Each type and brand needs to be customized to fit the specifications of the automotive manufacturer. An ECM needs to be properly configured by the manufacturer so the car can perform optimally, taking into consideration the engine specifications and other factors. The same system is used to tune to different cars even if OEM suppliers are offering different engine computer products, and a good starting point is that ECM systems are broken down into categories such as fuel type (diesel or gasoline), engine size, and so on. It can be disturbing and nerve-wracking to think that the ECM System can go bad just like any other car part, so feel free to check our website or homepage now if you have ECM problems and you need ECM repair.
