High-Performance Fuel Injection Sys-OP Paperback – September 22, 2009

Greg is an OEM calibrator who actually went to college for this stuff. He's worked at Ford and GM, in the tuning department. He's had his own tuning shop. He teaches tuning. He teaches SCT's Advanced Tuning class. This is his second book. I've read them both, and attended his SCT class. I can guarantee that they don't come any sharper than him, when it comes to tuning.As an added bonus, he seems to know how to write in way that's easy to understand, no matter what your experience level. I've read lots of other tuning books, been to EFI University and read Ben Straders book as well, and in my opinion none of them are near as good as this book. So go buy it.This book covers speed density computers more specifically, such as FAST, Big Stuff, Accel, etc. But the details in it still apply to all tuning. His other book, Engine Management: Advanced Tuning covers the Mass Air cars (most OEM EFI systems) a little more closely. Either way, if you're trying to learn to tune, or want to know more about how EFI works, buy both books. Unfortunately, I can't say very good things about any of the other tuning books I've read. Most are poorly written, way to short and simple, or just don't help much.

Book made great sense in learning what my tune shop is actually doing with my car

The guy who wrote this book has a mindset focused in join the most important theory to the real world pratices. The subjects are organized in a logical and evolutionary sequence. The colored ilustrations allow the learner get a clarified understanding. The words used and the way he expresses means that he is not an amateur. I'm sure he is a very experienced professional.While reading the explanations it's possible to imagine like you were inside a dyno environment seeing all the calibration process. From inexperienced to expert, a lot of tips can improve their knowlege. Some explanations require the reader to go deep in engine theory, specially about combustion process.About me: I've been working as engineer for NAVISTAR diesel engine group in Brazil. On weekends I work as a engine builder specially for dragracing applications. Here in Brazil our prefered engine for racing is the VW ABA 4cyl 2.0 Liters and I've got 1180 Hp on this little sport compact machine with just 3.6 bar intake pressure.

This isn't going to be like my other review of this author's previous book. This one is great value for money except for the fact that after reading it you become a little depressed when you have to accept the fact that you cannot clone him and keep him around your shop 24 hours a day. I dare you to find a better book about this stuff. I literally dare you.UPDATE:(6/4/2014)I'm going to be a bit harsh and deduct one star from my previous 5 star rating because upon giving this book a second read I DID discover one "small" thing that I think is significant enough to hamper a reader of this book in their attempts to fully grasp what is being explained. If you jump to chapter 10 there's a perfect example you can use to follow my logic. At the bottom left corner on page 76, Greg begins to explain a topic of particular interest to most tuners (especially myself)which is the process of populating the volumetric efficiency table, without the luxury of a reference base map to use as a start point.Now while I find no fault with the actual information that is presented, I do think that the principles would be much easier to grasp and to follow if the information coincided with what is displayed in the table snapshots next to what is being read. So for example on page 78 the 3rd column of text begins to explain where to apply an RPM specific correction to an entire column and it goes on to advise using this correction value to populate all of the values in the VE table above this same engine speed. Meanwhile there are a whopping FOUR snapshot table illustrations surrounding this body of text but not one of them shows an example of what you should see after applying these corrections. Therefore even though both the book and the illustrations give excellent information, The illustrations don't reinforce exactly what you're reading but rather attempt to tell their own story in their own way. Even if this approach was decided upon by the author as the best way to present the information, I still think that certain topics such as the one in my example should be carefully illustrated with graphic tables to reinforce what is being read by providing an easy to follow graphic example.

I have skimmed through many EMS tuning books and never bought any of them because they were too complex, or spoke too much about irrelevent builds, EMS history, etc. This book gives a nice intro and then gets to the meat!This book is by far the most methodical, guiding you step by step through the tuning process, while providing knowledge and tips along the way.After reading this book, I can LITERALLY look at my guage cluster and picture WHERE on a VE/FUEL map my engine curreently resides in just based on my rpms, mph, and selected gear. Its an amazing book, that really makes tuning understandable and practical to the everyday automotive enthusiast. If your new to EMS tuning, get both this book, and his previous one, which spends more time explaining the 101's of engines, sensors, etc.Get This Book!!! no other even comes close!!!!

Greg really did a great job on this book. I work at a small speed shop as a tech and one skill I have been wanting to add to my arsenal is tuning. We do in house tuning but its hard to get someone to devote the time to teach you so I bought all of the literature I could find and will be attending the tuning school. I was pleasantly surprised when I read the book. It contains a lot of theory and is more in depth than I expected. FYI this book deals exclusively with speed density systems aimed mostly at stand alone systems.
