What is the job of a carburetor?
The job of either a carburetor or fuel injection, whether it’s mechanical or electrical, is actually simple, and that’s to meter the correct amount of fuel based on the amount of air flowing into the engine. (I address volume versus mass shortly.)
What is EFI versus carburetor?
By design, a carburetor meters fuel based on the volume of air flowing into the engine. EFI meters fuel based on the mass of air flowing into the engine. Thus , EFI is able to make changes to the fuel metering in real time based on the quality of the air entering the engine.
What is a throttle body?
The throttle body (TB) is an integral part of any EFI system, and just like the throttle blades of a carburetor, it regulates the air flowing into the engine. TBs can have a single throttle blade, dual throttle blades, or a pair of dual throttle blades.
How does a handheld controller work?
Systems that include a handheld controller require you to input some basic data about your combination into the ECU via a series of questions or available choices. After you’ve done so, a base tune is created in the ECU from the data you’ve input. These types of systems are designed to be easily configured and to get the vehicle running smoothly in short order.However,this kind of interface limits your tuning options to those that are only available via the handheld controller.
What is an ECU?
This is the heart of any electronic fuel injection system. It takes input from the various sensors so that it meters fuel based on parameters programmed into it. No different than a personal computer, an ECU employs a powerful microprocessor to ensure that fuel metering is immediate, smooth, and responsive. Some ECUs can also perform engine management, in which case they may be referred to as engine control modules (ECMs). In other cases, the ECU can also manage the control of an automatic transmission, such as the Holley Dominator, for example, in which case they can be referred to as a powertrain control module (PCM). For simplicity, in this book, I stick to ECU.
How to remove a carburetor from a car?
Remove the Carburetor. Take off the fuel lines and hoses that come from the carburetor. The carburetor is mounted to the manifold by nuts. Use a wrench to remove these and take the carburetor off. If it is in good shape, it's possible to sell it as a used part; if not, then it can go to a junk yard.
What is the purpose of a throttle body?
The throttle body regulates the air going into the valves. Universal models are the easiest for conversions. Bolt the throttle body on and hook it up at the throttle linkage. This is connected to the accelerator pedal. An idle air controller is needed with the EFI throttle body.
Do injectors need to be installed?
Injectors need to be installed into the intake manifold. Welding will be involved, so it may be necessary to bring the vehicle or part to a machine shop. Most intakes can be modified using weld in bungs for injectors. Once the injector spot is available, the injectors slide into place and with o-rings for the seal.
Does an EFI throttle body have an IAC?
It opens or closes the passage depending on how much air is needed in the manifold. Most throttle bodies come with an IAC already installed. Install the Sensors. In order for the EFI system to monitor and change the injection, several measurements need to be taken.
How does the Go EFI 4 work?
With the Go EFI 4 unit installed and running, the boys set up the ignition system according to the instructions and ran the timing-control system as well. The ute was then placed on the dyno for some testing — more for the boys’ own interest than it being a requirement; after all, this is a system the competent DIYer can do at home. The engine was run up, letting the system make changes by driving it at certain rpm ranges and loads, as you’d do on the road. Then some full-power runs were made, to let it tune in the top end. The result was impressive — a gain of 20hp and 11lb·ft; not just an improvement at peak, but, as you can see from the dyno sheet, an improvement through the rev range — don’t forget this is on a vehicle that was already well tuned.
What pressure does a Go EFI need?
The fuel-supply system is next in line. The Go EFI needs to be supplied with fuel at a pressure of 58psi, so the 7psi system that supplies the existing carburettor won’t be suitable. Fortunately, FiTech offers several easy solutions to this problem.
What is an EFI system?
All of the company’s electronic-fuel-injection (EFI) systems are throttle body–type fuel-injection systems that bolt to any four-barrel intake, making them just the thing for swapping any carburetted V8 engine to EFI. The system requires you to do a simple initial set-up through its supplied hand controller, from which the FiTech computer creates the base map required to get the engine running. Once running, the system makes continuous adjustments to self-tune the air–fuel ratio (AFR) to the optimum target AFR you provided. This means that the AFR will be correct no matter what weather or altitude the engine runs in — the system will always make sure your engine runs at its optimal performance.
How long does it take to charge an electric golf cart?
It can take anywhere from 3 to 10 hours to fully charge your electric golf cart. This is assuming the battery is nearly discharged.
