Data points are just words, but when connected with a squiggly line they tell a story….

“Making Sense of Squiggly Lines” lays the foundation of knowledge required to analyze the data recorded on a race car.  Its simple approach is perfect for beginners, while the author’s meticulous attention to the details and pitfals of data will improve even the experienced engineer.

This book is comprised of 144 pages with 166 figures and 15 tables.

What others are saying….

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!

I’ve started through it, and I must say that this is the Buddy Fey replacement that we’ve been waiting for!

So far I’m about 60 pages into the book and loving it. The book is going to cost a lot more than I thought because it looks like I’m upgrading my data logging capabilities!

I have been involved with the San Francisco Region Driver School since the early 70’s and for the past couple of years have been leading a group for advanced and experienced drivers. In the school last year I recommend the students get your book and read it regardless of whether they had a Data Acquisition system or not, it is a great book on competition driving, and should be read as much for the driver coaching as for the data acquisition. Thank you for a fabulous book!
