Converting from a carbureted fuel system to electronic fuel injection improves the performance and driveability of any classic vehicle. EFI differs from carburetion in that the engine control unit optimizes the air/fuel ratio so the engine performs at its best at all times. Installing a complete aftermarket EFI system may seem complex, but it is within your reach by using the clear and easy-to-understand, step-by-step instructions in this book.
A variety of EFI systems are currently available: throttle-body injection, multiport fuel injection, stack systems, application-specific systems, and special application systems. Author Tony Candela reveals the attributes of each so you can select the one that's ideal for your car. He shows you how to install TBI and MPFI systems as well as a complete rework of an improperly installed and poorly functioning EFI system. He also explains each crucial step for calibrating these systems in your own garage. You learn how to optimize your electrical and fuel delivery system as well as integrate ignition and computer control with aftermarket EFI systems.
A well-installed and well-tuned EFI system greatly improves the performance of a classic V-8 or any engine because the system delivers the correct fuel mixture for every operating condition. Your engine will deliver quicker starts, better fuel economy, and improved and efficient performance. With this book, achieving all these benefits is at your fingertips.
