Alat Peraga ini dapat menunjukkan struktur dan prinsip kerja sistem kontrol elektronik pada mesin mobil, sehingga dapat membantu siswa dalam memahami masalah sistem kontrol elektronik pada mobil. Fuel gets pumped up from the tank by means of a fuel pump out to a fuel injection rail, then into person injectors which are inserted directly into the intake manifold. Genuinely astonishing for a setup that reflashes the stock computer system, files are uploaded in mere seconds and optional two- and three-bar MAP sensors for forced-induction applications suggests massive increase can be had with no aftermarket EFI.
The $450 package involves straightforward-to-use Windows-based application and interface cable, and enables complete manage over fuel and spark maps. It’s dependent on a quantity of elements such as the density of the air, how a lot air and fuel are becoming ingested, engine load, and the air/fuel ratio. Ben is a expert EFI technique builder and tuner with a passion for sharing his know-how with other people.
The patented Direct Fire ignition program characteristics a separate coil pack for each and every pair of companion cylinders, which according to Electromotive, provides a lot more energy and ten occasions a lot more spark duration than competing capacitive-discharge systems. A couple of drawbacks to a mass flow method include its value and overall design, which can restrict airflow in higher-horsepower engines.
The system bundles with each other an intake manifold, fuel rails, injectors, fuel-pressure regulator, a higher-stress fuel pump, a carb-style throttle-body, a wiring harness, an ECU, and all needed sensors. The TwEECer plugs into the service port on EEC-IV and EEC-V Ford ECUs and makes it possible for full alteration of fuel and ignition curves with a laptop personal computer.
An engine’s fuel injection technique should handle three things: how substantially air an engine has, how substantially fuel is needed to mix with the air (dependent on situations), and what the proper timing for the ignition of the mixture will be. All the fundamentals of energy that dictate how well an engine performs are controlled by a contemporary auto’s EFI system.

When you obtain a new Harley Davidson, aftermarket pipes are most likely the first main upgrade you will make, this article will discover and supply comparison of some of the additional well-liked options available for Sportster exhaust systems. Very good news for us: GM’s mighty Gen III little-block comes with an equally mighty pc to handle it. The brainchild of an elite group of bandit hackers, Windows-based HP Tuners VCM Suite Pro computer software makes it possible for full alteration of fuel and ignition curves within the factory PCM working with a laptop computer. After years of traveling and tuning systems all more than the country, Ben realized that there is still a substantial void of data in the overall performance sector about the how’s and why’s of EFI operation. Fuel flow is controlled by varying the pulse width or duty cycle of the injector.
Carputing revolutionized late-model GM EFI tuning with the introduction of LT1-Edit in 1999, which permitted levels of tunability usually related with aftermarket computers at a fraction of the price. Soon after you enter bore and stroke dimensions, compression ratio, cam specs, fuel stress, injector size, and cylinder head specs, CalMap automatically generates a custom baseline system to get you up and operating. The nucleus of just about every EFI technique is the Powertrain Manage Module (PCM), which interprets inputs from the sensors and relays directions to a variety of engine components. For option fuel applications fuel rail pressure and temperature sensors are also utilized.
Engine companies can even perform most of the technique integration in their own laboratory. Getting the technical know-how of how an OEM Electronic Fuel Management Program performs I had a look at systems at present accessible on our Regional marketplace. Start out-up and warm-up are prime examples, as a lot more fuel is required in cold temperatures.
Growing fuel stress is an selection, but escalating the fuel pressure modifications the calibration of the injector. It is not as widely employed as some of the other systems on the market, but John Meaney-the Godfather of aftermarket EFI and the man behind BigStuff3-invented the standalone systems that ultimately became identified as ACCEL DFI and Rapidly. Tuners can also control turbo enhance, nitrous, torque-converter lockup, shift lights, cooling fans, and a 3-step rev limiter.
Painless Performance has you covered with its new Perfect engine management program. Here’s a look at some of the far more well-known EFI systems on the market plus some suggestions on how to get began. As soon as a baseline plan is established, fuel and timing maps and idle speed are fully adjustable with a handheld calibration module. For example, you can alter from a fuel economy to a performance or nitrous tune on the fly.… Read more ...
