engine control unit programming

Programming an ECU typically requires interfacing the unit with a desktop or laptop computer; this interfacing is required so the programming computer can send complete engine tunings to the engine control unit as well as monitor the conditions of the engine in realtime. By modifying these values while monitoring the exhausts using a wide band lambda probe, engine tuning specialists can determine the optimal fuel flow specific to the engine speed's and throttle position. The device detects eventual connection or communication errors thanks to the concept of its state-of-the -art design. So from these references, I think it is safe to say that there is no ambiguity … Experimental engines have been made and tested that have no camshaft, but have full electronic control of the intake and exhaust valve opening, valve closing and area of the valve opening. Most modern engines use some type of fuel injection to deliver fuel to the cylinders. This can be useful for identifying engine stalls, misfires or other undesired behaviors during a race. This process first saw fruition in 1980 with fuel injected Cadillac engines, followed by the Pontiac 2.5L I4 "Iron Duke" and the Chevrolet 5.7L V8 L83 "Cross-Fire" engine powering the Chevrolet Corvette in 1982. This process is often carried out at an engine performance facility. A significant portion of the power that an engine actually produces is used up just driving the valve train, compressing all those valve springs thousands of times a minute.

[6] The high volume ECU that was installed in GM vehicles from the first high volume year, 1981, onward was a modern microprocessor based system. In such an engine, the ECU controls the time in the engine cycle at which the valves open. Popular Mechanics. Additionally, there will be an optional programming assignment in the last third of the semester. It takes specialized knowledge and specific tools to repair, not replace, an ECM. Another even more significant advancement will be the elimination of the conventional throttle. A special category of ECUs are those which are programmable; these units can be reprogrammed by the user. We can also … Idle speed is controlled by a programmable throttle stop or an idle air bypass control stepper motor. Modern ECUs sometimes include features such as cruise control, transmission control, anti-skid brake control, and anti-theft control, etc. Under a sudden increase in throttle, the valve opens in the same intake stroke and a greater amount of fuel is injected.

The engine control module (ECM), or engine control unit (ECU), manages your vehicle’s air fuel mixture and emission control systems based off input from the sensor’s in the engine bay. Imagine that this engine is used in a propellant pack for a space walker whose mass is 50 kg. Your Control Module headquarters for all remanufactured modules. Maple is technical computing software and math software for Engineers, Mathematicians, Scientists, Teachers and Students. The 1990 Cadillac Brougham powered by the Oldsmobile 5.0L V8 LV2 engine was the last carbureted passenger car manufactured for sale in the North American market (a 1992 Volkswagen Beetle model powered by a carbureted engine was available for purchase in Mexico but not offered for sale in the United States or Canada) and by 1991 GM was the last of the major US and Japanese automakers to abandon carburetion and manufacture all of its passenger cars exclusively with fuel injected engines. This kind of electronic control is less common in piston-engined light fixed-wing aircraft and helicopters than in automobiles. We Have All Makes And Models Of PCM- ECM -TCM -BODY CONTROLS. (April 14, 2012) http://www.popularmechanics.com/_mobile/cars/news/industry/4347704, Allen, Mike. The ECM is basically an on-board computer in your car -- it's composed of hardware (a pretty standard circuit board) that's encoded with software (a program that tells the car how to run). Air–fuel mixture control of carburetors with computers is designed with a similar principle, but a mixture control solenoid or stepper motor is incorporated in the float bowl of the carburetor. The disadvantage of such systems is that the precomputed values are only optimal for an idealised, new engine. It is open-source and freely available on MacOS X, Windows, and Linux. Typical modifications that may require an ECU upgrade can include turbocharging, supercharging, or both, a naturally aspirated engine; fuel injection or spark plug upgrades, exhaust system modifications or upgrades, transmission upgrades, and so on. Water temperature correction: Allows for additional fuel to be added when the engine is cold, such as in a winter cold-start scenario or when the engine is dangerously hot, to allow for additional cylinder cooling (though not in a very efficient manner, as an emergency only). You can now replace your faulty Volvo ECU or Toyota ECM with a rebuilt engine control unit, at a fraction of the cost of a new one, without sacrificing the quality or reliability. "Toyota Sudden Acceleration Backlash." If the ECU has control over the fuel lines, then it is referred to as an electronic engine management system (EEMS). The first production engine of this type was invented (in 2002) and introduced (in 2009) by Italian automaker Fiat in the Alfa Romeo MiTo. The fuel injection system has the major role of controlling the engine's fuel supply. ECM Buying a pre-owned or remanufactured auto computer is much cheaper than the dealer. Definition: A control unit (CU) (or controller, same thing) is a piece of hardware that manages the activities of peripherals (separate devices attached to the computer, such as monitors, hard drives, printers, etc.) The development of integrated circuits and microprocessors made engine control economically feasible in the 1970s. The data logger usually has a capacity between 0.5 and 16 megabytes. MicroSquirt® or MegaSquirt-II™ can control up to two ignition outputs, meaning either can do a 4-cylinder engine with 'wasted spark' ignition. (April 22, 2012) http://www.popularmechanics.com/cars/news/industry/toyotarecalelectronics2010, Delphi. One of the earliest attempts to use such a unitized and automated device to manage multiple engine control functions simultaneously was the Kommandogerät created by BMW in 1939, for their 801 14-cylinder aviation radial engine.
