About this ebook

A practical guide to modifying and tuning modern electronic fuel injection (EFI) systems, including engine control units (ECUs). The book starts out with plenty of foundational topics on wiring, fuel systems, sensors, different types of ignition systems, and other topics to help ensure the reader understands how EFI Systems work. Next the book builds on that foundation, helping the reader to understand the different options available: Re-tuning factory ECUs, add on piggyback computers, or all out standalone engine management systems. Next Matt and Jerry help the reader to understand how to configure a Standalone EMS, get the engine started, prep for tuning, and tune the engine for maximum power and drivability. Also covered is advice on tuning other functions-- acceleration enrichments, closed loop fuel correction, and more. Finally, the book ends with a number of case studies highlighting different vehicles and the EMS solutions that were chosen for each, helping to bring it all together with a heavy emphasis on how you can practically approach your projects and make them successful!

Ratings and reviews

Lots of grear info on different EFI systems on different cars. I'm learning a lot about various components of an EFI engine. I'm not a mechanic, planning on building my own mega squirt EFI system.

Excellent book by DIYAutotune Guru(s), these guys have a lot of experience making it happen, the book is a quick and informative read. You'll want to same this one as a reference also!

Definitely a book worth reading if you are planning an EFI conversion. Lots of good info across many different approaches to EFI tuning or complete retrofit.

About the author

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.
