I've looked wide and far, and this is one of the few books that I have come across that seem like they try to address the actual subject of how to tune a car using a modern engine management system. Besides this book, I've also read another book you will find here on Amazon with "Engine Management Systems" in its name and a Ford Focus on the cover. Let me tell you, this book is far better because it gives you much more practial information. The other positive note is, this is probably the most recent book on the subject (that's worth reading) to come out.
To begin with, this book is a much easier read. The word count per page is not too high, it has some nice illustrations to break things up and help you visualize different concepts, and the author doesn't ramble on and on repeating the same stuff 5+ times throughout the book(like some other book I know). This book breaks the tuning process into several different stages surrounded with concepts that an aspiring tuner needs to understand and address about their particular vehicle before even getting to a dyno.
For some reviewers who said this book is incomplete and never gets to the good stuff, or that it's engineer b.s., I have a feeling that those people were looking for a book that's going to hold their hand for their particular engine management system and tell them if they have mods x, y, and z then to put 22 degrees of ignition timing in at a certain spot of their map. Not gonna happen.
I feel Mr. Banish is as clear and specific as he can possibly be in a book that appeals to everyone, without coming to your house to figure out the actual settings to input for you. He even concludes the book with a very nice summary that illustrates what the overall process is to correctly tune a car from the time you first modify the car until months after you had your dyno time. A plan of attack if you will, that should keep even a newbie on track.
I myself was not a novice before reading this book, not a professional either, but more of an experienced hobbyist. This book inevitably covers a few things most of us have heard before, but I even learned some new tricks and came to understand some concepts better than before (things that I even thought I understood fully before). A few things the author talks about are somewhat advanced/abstract, so if you don't have any first-hand experience with a standalone (like Power FC, like I have) or an intricate piggyback (such as E-manage), then a few things will likely fly over your head.
In conclusion, I can't recommend this book any more strongly if you plan on having any type of engine management on your car.
