Matt Cramer is an engineer with DIYAutoTune.com, an aftermarket engine electronics firm. He is the coauthor with Jerry Hoffmann of Performance Fuel Injection Systems HP1557. Jerry Hoffmann is the founder/CEO of DIYAutoTune.com. With an IT background and being a lifetime car-guy hobbyist, he found a need for affordable engine management and education during one of his own projects when turbocharging a personal car and melded his computer career with his love for cars. His company specializes in equipping do-it-yourselfers to actually hand-build and implement electronic fuel injection systems in their own garage. And as such Hoffmann has installed and tuned EFI systems on numerous vehicles, street-driven classics, road-course- club racers, drag racers, and land-speed cars out at the Bonneville Salt Flats. His aim is to help others understand EFI in a practical hands-on manner, with less interest on the engineering ease and more focus on the practical need-to-know-how, and to empower people to affordably and knowledgeably build and implement their own EFI systems on their favorite automotive monstrosities.
We've all heard that an educated consumer is a better customer. It would seem that authors Jerry Hoffmann and Matt Cramer of DIYAutoTune are firm believers in this axiom. Their new book, Performance Fuel Injection Systems, expertly walks readers through the processes and pitfalls of working with aftermarket fuel-injection systems. Despite their MegaSquirt-heavy business model at DIYAutoTune, the authors deliver an even-handed look at all of the players in the market. While this book is a must-read for beginners, we're keeping it on our shelf to use as a reference for future conversions. - Grassroots Motorsports Magazine, reviewed by Per Schroeder, November 2010 Five Stars *****
