Fuel injection as a performance fuel choice is not for the faint of heart or wallet. However, the last few years have seen a dramatic reduction in prices, and a dramatic improvement in the quality and ease of use of these systems. Of course it is possible to use a factory system for a particular application, but you have to know the requirements for that system and adhere to them. We discuss the difference between Speed Density systems and Mass Air Flow systems, and review basic systems as well as sophisticated sequential systems that need to keep fuel and timing precisely controlled to keep the engine between the fenders. With high performance parts it can take less than a second of poor programming to destroy and engine. Of course, that isn’t true just for fuel injected engines, all engines are subject to failure with even slight miscalculations or adjustments. I once melted 5 of the 6 pistons in my twin turbo drag car (in first gear!) just from switching from fuel that I had blended to performance fuel I bought at the drag strip. I won’t make that mistake again!
One of the most difficult things about fuel injection is programming. The first aftermarket fuel injection system I ever used was adjusted by turning tiny screws on the end of the controller. It wasn’t very effective. As a matter of fact it was so anemic I talked the owner into removing it and sticking a four barrel carburetor on it. It ran really well then. But times have changed and the fuel injection sytems available are terrific. Installation is easy, although the programming might take you some time. I will keep the Fuel Injection Handbook up to date as to who is doing what with their products. Some of the newer systems have eliminated the need for a laptop to make adjustments and come with software that adjusts to your powertrain automatically.
