If you’re looking for an EFI system for your vehicle, you’ve come to the right place. There are many different types, including the Analogue type fuel control circuit 30′, the MSD 2900, and the Holley Sniper 550511. In this article, I’ll explain the differences between these and more. Hopefully, this information will help you make the best decision for your vehicle.
Analogue type fuel control circuit 30′
An analog type fuel control circuit is used to regulate the flow of fuel to a vehicle engine. The fuel supply rate depends on the temperature of the engine, so the fuel required during cold start-up is higher than that needed for a hot start-up. To improve engine start-up, fuel enrichment schemes have been proposed. However, the fuel needed for an engine during cranking is not a linear function of its temperature. Therefore, it is critical to supply fuel at a rate that is proportional to its cranking speed.
The circuit includes a suitable DC voltage supply, a plurality of electrical impedances coupled to the DC voltage supply, and a capacitor. The circuit controls the switching devices as a function of the voltage across the capacitor and the DC supply. The circuit charges the capacitor from the DC supply, and then selectively switches the electrical impedances into a conductive circuit with the capacitor. This causes the capacitor to discharge at a frequency proportional to the engine cranking speed.
The MSD Atomic 2 EFI Fuel System is a premium aftermarket kit that can be installed directly onto your vehicle. These kits offer enhanced drivability and idle stability, and wide-open throttle horsepower. They are also aesthetically pleasing and cost-efficient. If you are interested in improving the performance of your vehicle, an Atomic EFI system is worth the money. Here’s a closer look at each part.
The Atomic throttle body assembly bolts onto your stock 4150 intake manifold. This system features two 100-pound-per-hour Fuel Injectors and is capable of supporting up to 650 HP naturally aspirated and 635 HP in forced induction applications. The Atomic ECU features ignition timing control and self-learning fuel maps. You will notice an increase in wide-open throttle horsepower and stability. In addition, the Atomic throttle body assembly offers plenty of clearance for your stock air cleaner.
Holley Sniper 550511
The New Holley Sniper 550511 EFI System is the best overall aftermarket EFI system on the market. It’s inexpensive and offers excellent functionality. However, if you’re on a budget, you can still find a great system by opting for a budget-friendly option such as the FiTech 30021 Go EFI System. Listed below are some of the pros and cons of each system.
The base Sniper comes with a timing control. It provides an adjustable 18-34 degree range of timing, so you can smooth out detonation issues. You can also use the throttle to build vacuum. In addition, the Sniper is compatible with a wide range of fuel-injection systems, so you can choose the right one for your needs. It’s worth noting that the EFI Self-Tuning Kits are compatible with many vehicles.
FiTech 30021 Go
The Go EFI Classic Black fuel injection system from FiTech Fuel Injection is a new technology that eliminates common cold start problems, hesitation, vapor lock, and flooding. The black fuel injector housing hides the injectors and has an externally mounted ECU. The Go EFI Classic Black is rated at 550 horsepower. It comes with all the necessary hardware and is available with a variety of features.
This fuel injector cleaner increases performance and fuel efficiency. Modern fuel injectors run with very close tolerances. The PCM receives a trigger signal from the crankshaft and camshaft position sensors. A worn-out belt prevents the position sensors from synchronizing and can cause the wrong signal. To fix this problem, install the FiTech 30021 Go EFI system. The installation process is easy and requires no technical expertise.
