Finally, after many years waiting for a great book on the analysis of race car data, and over a decade since the last good book on the subject went out of print, a new book titled Making Sense of Squiggly Lines is now available!

Making Sense of Squiggly Lines

The Basic Analysis of Race Car Data Acquisition - Written by Christopher Brown

Data points are just words, but when connected with a squiggly line they tell a story...
Starting with the basic channels of data, this book shows the reader how to extract information out of those squiggly lines seen in a graph. It discusses in great detail the following channels of information: Speed, Engine RPM, Throttle Position, Gear, G Force and Steering.

This book contains 144 pages with 166 figures and 15 tables.
An introductory book which explores what can be analyzed, learned and understood from the complex world of race car data acquisition. The information gained from logged data can tell you where you are slow, where you are fast, and how to go faster.

What the Critics are saying

“I must say that this is the Buddy Fey replacement that we’ve been waiting for!”
Colin Harmer - Owner of Creative Motorsport

“A very approachable tome that focuses on driver engineering through the intelligent
use of data. Chris’ explanations are wonderful and the premise of the book (as indicated by the title) is well executed. Probably the best single book for learning what to look at first for the Club and Track Day driver. Highly recommended!”
Peter Krause - Professional driver and data coach

“One of the real gems is Chris’ analysis and explanation of using G data for driver improvement in braking and the different phases of a corner.”
Mark Dalen - Head of faculty at

About the Author

Christopher Brown has over 10 years of experience in all levels of racing from amateur SCCA to professional IndyCar, American LeMans and NASCAR series. He currently works for MoTeC USA. MoTeC is a company that builds engine control units and data acquisition computers for a variety of motorsport applications. Holding a Bachelor of Science in Mechanical Engineering, Christopher graduated with honors from Oregon State University. He also attended the University of Nottingham doing research in composite materials. While in England, Christopher had his first experience behind the wheel of a race car, attending the Jim Russell Racing Drivers School at the famous Donington circuit. He competed in many SCCA races winning at both the regional and national level, before shifting his focus to technical support full time. As both an engineer and a racer, his in depth knowledge and interpretations of data acquisition reveals itself through the book.
