I got my book by Andy Sabisch today and have read about a third of it. The way this book is written makes it real easy to understand how the ETrac works. When I was running the DFX I had the book by Jeff Foster and found some things in it that I had to go back over several times before it would sink in. I'm gonna read this more than once, so I get a full, or as close to full grasp of the ETrac before spring gets here. I can't wait for spring to get here.
