Читать книгу EFI Conversions - Tony Candela - Страница 7

INTRODUCTION

Let’s face it; the idea of converting from carburetion to electronic fuel injection (EFI) is incredibly exciting. In fact, this is one of the most commonly discussed topics among enthusiasts at local gatherings. If you’ve picked up a car magazine in the past five years, you’ve undoubtedly seen numerous articles on this topic, nearly as many as the topic of LS conversions. Most people I speak with have numerous questions that the confined space of a magazine article simply cannot address. This book addresses those questions in their entirety.

Some of you may recognize me as the author who writes books on that taboo topic of wiring and electrical systems. I have two such books in print, Automotive Wiring and Electrical Systems and Automotive Electrical Performance Projects. From time to time, I may refer to bits and pieces of those books where relevant. If you’ve read my other books, you’ve likely noticed my “comfortable informality,” as one reviewer put it. This book is no different, so have no fear of it reading like the instruction manual for the Retro Encabulator; view it on YouTube.

In addition to being that guy who likes wiring (weird, right?), I’m what most people consider a super-enthusiast. In Chapter 9 of Automotive Electrical Performance Projects, I illustrate a conversion from carburetion to EFI on my personal hot rod, a 1972 Oldsmobile Cutlass Holiday Coupe with a 6-71 blown big-block Chevy (sorry, Olds fans). That conversion turned out to be an incredibly simple one, and I’ve never looked back to carburetion. As it turns out, that project became the inspiration for this book.

Shortly after Automotive Electrical Performance Projects was published, I was at a local gathering with my car buddies. We sat in our lawn chairs and discussed EFI conversions at length, including my Olds. I discovered that there was much to learn and discuss regarding the topic. One thing was for sure, every one of them wanted to know as much as they could because they have all considered this upgrade for their own vehicles. A few months passed and my editor called. He and I had a nearly identical conversation and the rest is history.

A book of this nature deals with a lot of high-tech hardware, which is typically replaced or updated with the latest and greatest as the manufacturer makes improvements or introduces new technologies. The aftermarket has come a long way in the past few years and advancements in product offerings seem to be coming at a blistering rate nowadays. However, I’m confident that what you learn here is somewhat universal and it applies, generally speaking, to nearly any conversion of any manufacturer’s product.

As you’ve got this book in hand, I assume that you’re considering this conversion for your own vehicle. Nothing would make me happier than to know that you undertook it after reading this book. And you know what? It is really easy!
