All You Need to Know About Diesel ECM Programming

For modern diesel-powered vehicles, tuning can unleash the performance and fuel efficiency. Performance tuning involves usage of devices which are mingled into the term “chip”, involving modification of various operating parameters such as timing and fuel characteristics, in favor of maximum output, with little or no regard to vehicle emissions, with the aim of increasing performance, fuel economy, and modification or reprogramming of the factory calibration of an engine. When it comes to Em programming, it involves using a computer with microprocessor, with similar features and capabilities of your computer at home or office. 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 monitors and regulates the throttle position (indicating the amount of air and fuel needed to make power), the coolant temperature sensor (if the engine is running too hot), the voltage regulator (tracks and adjusts power), the fuel injectors (providing fuel on the right timing for optimum delivery), the position sensors (for camshaft and crankshaft of engine cycles), the mass airflow sensor, MAP (manifold absolute pressure) sensor (monitor different ways air affects the engine), the oxygen sensor, (measures exhaust quality), idle control, the EGR valve sensor (helps with emissions), and the ignition control (regulates the spark plugs).

The ECM systems are not designed by auto manufacturers but are rather one of the components that is sourced and customized. Only a few of Original Equipment Manufacturers (OEMs) make ECM systems for cars. Each brand and type must be customized according to the specifications of the automotive manufacturer. Proper configuration is very important for every ECM system so a car can optimally function, take into consideration the engine specifications and other relevant factors. The OEM suppliers offer different engine computer products with different features and benefits, and ECM systems are broken down into categories such as fuel type (diesel or gasoline), engine size, and so on.
