What You Should Know When Upgrading The Fuel Injection System On Your Vehicle

Upgrading your car to get more performance from the engine can involve many things, and adding performance fuel injection system parts may be something to consider. Before making changes to the electronic fuel injection in your vehicle, it is vital to understand the system and how to make changes without causing damage to the engine through poor fuel management. 

Fuel Injection Versus Carburation

Electronic fuel injection systems start replacing carburetors much earlier than most people realize. When the need for better fuel economy without performance loss started to rise, automotive manufacturers had to find alternatives, and EFI became popular. 

The fuel injection system uses a fuel map and sensors to allow the engine's computer to monitor conditions and regulate the fuel and air mixture used to maintain peak performance. EFI systems allowed the vehicle manufacturers to set up the vehicle's engines to perform well in different temperatures, elevations, and operating conditions that required standard carburetors to require tuning or adjustments. 

EFI fuel systems are becoming more advanced all the time. Performance systems can replace carbs and factory EFI to create fuel management systems that can account for the smallest change in the engine and make adjustments on the fly, and the driver never notices the change. Systems that are this sensitive often require some special knowledge to install and adjust but once the system is working correctly, it will make additional adjustments according to the program in the engine management computer.

Diagnostics And Repairs

One common issue with aftermarket EFI or electronic fuel injection systems repairs is if something goes wrong, they can require some specific equipment to repair. Electronic fuel injection system parts are not hard to find, but on some systems, the number of sensors that could affect how the system works can make diagnostics more challenging. 

If the EFI begins to malfunction, you may need an auto technician with the right computer system to determine where the problem is. A faulty sensor can cause problems mimicking fuel starvation issues because the data reported to the computer is wrong. When this happens, the computer tries to adjust and may make the engine run worse because of a data failure. 

When installing performance electronic fuel injection systems, it is best to use a system that allows the tech to adjust it easily and has the fewest sensors possible. Other electronic fuel injection parts can include injector nozzles, custom fuel rails, high-flow throttle bodies, and many other parts. Used together to create a system that performs well, these parts should last a long time without requiring replacement but look for performance systems that use factory sensors for better availability if you need to replace something along the way.
