I had bought this book on a recommendation over a year ago. I finally read it since I was getting into tuning my car. A lot of the modern day engine management stems from the original Bosch systems. This book goes over those systems.
While I wouldn't consider this book the best book out there, it does go over the basics of fuel injection and the different systems.
I did learn some things. For example, a 3-way catalyst works better with a slightly richer mixture or with a slight excess of air, which is why some cars have an air pump. That also may give insight as to why subaru's tend to run a little rich. It also may explain why the newer cars have an external air pump that pump air into the exhaust.
So there's some good fundamentals in the book. He speaks mostly of n/a engines.
There is a section on "high performance" tuning....however the jist of the section is that Bosch did a pretty good job at setting things up, and modifying it isn't too easy, blah, blah.
Overall....for the price it's worth a read. You'll probably pick up a few things you didn't know.
