Say you own a '60s muscle car which you've converted to electronic fuel injection. Depending on which aftermarket fuel injection system you buy, the instructions on how to set-up the system will vary from not very good to above average. Additionally, depending on what system you bought, the actual calibration process varies from being painfully difficult to reasonably easy.
This book, "Designing and Tuning High-Performance Fuel Injection Systems", fills a dire need in the enthusiast community for a text on how to calibrate an aftermarket or "stand alone" EFI system from scratch.
Author, Banish, is a car company Calibration Engineer by day and runs a well-respected, Michigan-based performance tuning business in his off hours. His expertise is a large part of why this book succeeds in its goal.
Not only does this book cover the calibration procedure, but it also covers subjects like the basics of combustion science, volumetric efficiency and airflow, fuel injector characteristics along with spark timing and its effect on cylinder pressure. All of these, when better-understood by the calibrator, make the process of tuning an aftermarket EFI system more seamless.
This book is not for beginning DIYs. Some basic understanding of electronic engine controls is necessary for the book to be useful. Additionally there is math and chemistry involved when the Author writes of subjects like combustion, volumetric efficiency and cylinder pressure. Thankfully, Banish's discussions involving of math and algebra are limited and, in general, not required to get substantial benefit from the content in the book.
The final chapter of the book is a case study of a 1969 Corvette the owner of which was installing aftermarket fuel injection to the car's 427 consisting of an Edelbrock dual-plane intake, a four-hole throttle body, 30 lb/hr injectors and a "Megasquirt" ECM. The case study was fascinating reading and one of the best parts of this book.
If you want to learn about from-scratch calibration of aftermarket electronic fuel injection and engine controls systems, "Designing and Tuning High-Performance Fuel Injection Systems" should be at the top of your list of information sources.
