Tuning books, with Amazon links for your convenience.
These are in the order that NSFW likes them, only because he (I) wrote most of this page:
How to Tune and Modify Engine Management Systems (Jeff Hartman)
NSFW’s take: this is a great ‘first book’ if you want to get into tuning. This book provides a nice introduction to the subject by explaining electronic engine management from first principles, and goes on to include a lot of useful information about ECU tuning. I was underwhelmed with the second half of the book, which reads like a magazine, but the first half alone still was well worth reading.
Engine Management: Advanced Tuning (Greg Banish)
NSFW’s take: More advanced that Hartman’s book, this book is aimed at people with a good understanding of the fundamentals.
Forced Induction Performance Tuning A Practical Guide to Supercharging and Turbocharging (A. Graham Bell)
NSFW’s take: Recommended, though more for its explanation of high performance engine design than for its ECU tuning information. This book contains s a lot of historical information about the development of turbochargers and superchargers which provides a perspective and background knowledge that I have not seen elsewhere. It leans more toward the physical aspects of engine tuning (e.g. intake and exhaust design). Very interesting for background and theory.
Maximum Boost: Designing, Testing, and Installing Turbocharger Systems (Corky Bell)
NSFW’s take: Lots of technical information about all kinds of stuff from intercoolers to injectors to exhausts. Reading this book was time well spent.
Street TurbochargingHP1488: Design, Fabrication, Installation, and Tuning of High-Performance Street Turbocharger Systems (Mark Warner)
Nobody has reviewed this one yet.
NSFW’s summary: Hartman and Banish cover enough to keep up with the conversations in the RomRaider forums. The others are good too, but if you only read two books, I recommend those two.
