Although these microprocessors make it more difficult for you to work on your own car, some of them actually make your car easier to service. Cars today might have as many as 5 0 microprocessors on them. How Car Computers Work Each year, cars seem to get more and more complicated. If you are planning to replace the entire multi-port system, then expect to pay about $4,000 depending on the make and model of the vehicle. Expect to find a computer, tuning software, wiring harness, sensors and cable for computer interface in an aftermarket kit. An aftermarket system can supply real time tuning, particularly if the manufacturer has yet to make a tuning software program for your engine (not all engines have their own programs).

Many drivers look to upgrade to aftermarket sequential systems because the stock systems are quite limited and the tuning software used is very inexpensive. While carburetors really are best for adding more horsepower, the SEFI systems require much less maintenance, are very reliable, make driving easy, and reduce noise and emissions. Almost all cars are sold with fuel injection, but to increase performance there are aftermarket systems available. For those that are looking for very fast handling response and the ultimate in performance, a sequential system is the best option. However, a sequential system is not the most common. When to Use SEFIįuel injection systems are very common today. This in turn also increases the cost co st of the system.

Because the system is more complicated it is very difficult to install and most drivers will require professional installation. The electronic control is more complicated and requires additional equipment to run properly. Sequential systems are also more expensive because they require an additional wiring harness that is used to ensure that the injectors pulse sequentially. A V6 engine will need 6 injectors and a V8 would need 8 injectors. Disadvantagesīecause there is a single injector for each cylinder, the larger the engine the more expensive the system.

This is very important where vehicles are being produced p roduced to meet stricter emissions. Because fuel is used more economically, the emissions released are lower. The throttle response is immediate, which allows for very rapid changes in the fuel to air mixture. Because the fuel is altered for each cylinder, you can potentially get the best performance out of the engine that is possible. This type of injection also produces much lower emissions and provides even better fuel economy.

For systems that do not use sequential fuel injection it will be necessary for the entire engine to complete a revolution before the fuel to air ratio can be altered. More or less fuel can be released when the next intake valve opens.

The main advantage of a sequential system is that the entire system has a fast response time when the driver makes a quick change. While sequential variable fuel injection has many benefits, direct injection is quickly becoming the system of choice and is replacing repla cing the SEFI systems. Other multi-port systems will fire all the injectors in groups no matter if the cylinder is ready or not. So in essence, the individual injectors work by themselves because they are fired individually. Sequential fuel injection is a type of multi-port fuel injection system in which each injection valve will open just before the cylinder intake valve opens.
