The elimination of cams, lifters, rockers, and timing set reduces not only weight and bulk, but also friction. See the image on the link below to help me explain the numbers. The development of integrated circuits and microprocessors made engine control economically feasible in the 1970s. OdinEidolon wrote:I wonder if this kind of software update updates only SW or also HW numbers - this'd be very strange, but I also noticed the HW numbers on similar-aged 406s vary wildly.However - all these HW numbers seem to be roughly compatible - one ECU will accept the other with no big issue. I mean officially, the part number changes with each update even though the pcm hasn't been replaced. In the Electronic Fuel Injection system, the ECU reads signals about manifold vacuum, engine speed and temperature. Many different types of ECUs, including an ECM (Engine Control Module), PCM (Powertrain Control Module), BCM (Brake Control Module), GEM (General Electric Module) … on my ECU, the top, that says 'MEC11-210' is the same as the image. There may be more than one meaning of ECU, so check it out all meanings of ECU one by one. If the ECU has control over the fuel lines, then it is referred to as an electronic engine management system (EEMS). They also may communicate with transmission control units or directly interface electronically controlled automatic transmissions, traction control systems, and the like. While the mentioned parameters are common, some ECUs may provide other variables in which a tuning software could potentially modify. The ROM type of system is amenable to tuning if one knows the system well. What Do Plastic Recycling Symbols Mean? This, of course, is impossible with a normal camshaft, which opens the valve for the whole intake period, and always to full lift. Obviously Boise State under-estimated ECU and because of that they dont get the bowl win. Oxygen sensors tell the ECU whether the engine is running rich (too much fuel or too little oxygen) or running lean (too much oxygen or too little fuel) as compared to ideal conditions (known as stoichiometric). ECU: Extended Care Unit (medical care) ECU: European Chiropractors' Union (est. For the next stroke, the ECU calculates engine load at the new, higher RPM, and decides how to open the valve: early or late, wide-open or half-open. Modern ECUs use a microprocessor which can process the inputs from the engine sensors in real-time. Some wicks have 3 different numbers for the wick size. ECU means Electronic Control Unit. Basically, the valves are opened by hydraulic pumps, which are operated by the ECU. Cylinder deactivation, for instance, could be made much more fuel efficient if the intake valve could be opened on every downstroke and the exhaust valve opened on every upstroke of the deactivated cylinder or "dead hole". Till now you might have got some idea about the acronym, abbreviation or meaning of ECU on my ECU the third box that says says '0328' in the image says '0726; on my car. Do you know your ‘C’ from your ‘D’? Those are manufacturing numbers actual ECM number can be down loaded if the ECM powers up.
