Hot off the press - there is finally an excellent, up to date book out on racecar data analysis! Analysis Techniques for Racecar Data Acquisition is the title, author is Jorge Segers. Published in the US just a few weeks ago.
We have the book in stock, it is available on our website at http://www.race-technology.com/home_8.html
Shipping charges will be waived for the book, though the system will show a $15 shipping fee.
We'd appreciate anyone buying through us, of course, as a site sponsor and all, but by hook or crook get a copy and read it if you have any interest at all in race or autocross data logging and analysis. You'll spend many happy hours pondering, there's lots to think about in there.
No more hunting the Internet for used "Data Power" books for $1400!
