Performance Fuel Injection Systems HP1557: How to Design, Build, Modify, and Tune EFI and ECU Systems.Covers Components, Sensors, Fuel and Ignition ... Tuning the Stock ECU, Piggyback and Stand Paperback – Illustrated, August 3, 2010

Ok -1) So pick your favorite car magazine.2) Now try to remember the best 'tech' article that you ever read in that magazine.If you're like me, you found that 'tech' article fascinating and informative; maybe you couldn't put it down until you finished it, and then you ran to the garage to try out what you learned.This book is like that - except it's a WHOLE BOOK instead of just some little snippet!I got the book in the mail the day before I went on a short vacation to the beach. I plopped onto the sand, and read every single page - cover to cover. My wife thought I was nuts to be reading a fuel injection manual instead of frolicking in the surf. The book is THAT good.It really spells out how all the sensors 'talk' to each other, how to map out what your EFI system should look like for your particular application, what components you can borrow from existing cars, and several other nice tips.If you know nothing about DIY EFI, this will give you a great overview. If you know think you know everything about DIY EFI, this book might teach you something.It is NOT a step-by-step instruction manual - but it will provide excellent guidance and clarity to you as you build your system. Most of the info you would need to build your own EFI system is online somewhere, but it can be tough to understand the jargon and the measurements. This book helps keep you on course as you learn.Well written, well worth the money - even if you never build your own system, it'll help you understand how your car works. It may even help you make a basic repair the next time your factory system breaks down.Love it.

If your'e just getting started in EFI this book is ideal for you. Covers all the basics from fuel line and sizing to airflow metering and which setup is going to best for your application. Gives a run down and basic listing of most known after-market stand alone EFI systems and what they will allow you to accomplish, making deciding on which unit you want a snap. Where this book shines is from chapter 12 on. Explaining, in enough depth to ensure a number of re-reads, how to configure and tune your engine management system. The detail here is brilliant, giving you a place to start with everything from calculating and finding ideal ignition timing to engine fueling needs in warm-up and acceleration enrichment. There are almost step by step instructions here when you get to the dyno or a track to begin tuning. There are also three system installs in the rear of the book explaining the use of the Megasquirt system on a V8, a turbo MR2 and a Zetec kitcar. The diagrams, tables and photos are of excellent quality. At 150 odd pages it is not surprising how little fill has been required to cover what will get you from an EFI zero to an EFI hero, well maybe not hero but enough to get your vehicle running. Excellent.

I will start of saying,at first glance the artwork and the choice is pretty spot on.I purchased this book,not just because i know of the authors,but rather as to see their take on laying it down for everyone who gets scared of the technical stuff.And I must say I am pleased with their explanation on this sometimes confusing hobby.I have attracted a lot of interest in it (letting my friend read it) from people who have been scared to go with their own custom EFI conversion's,just by showing them ,hey,see I told ya it is not so confusing to understand.Also I have learned some fuzzy things about the hobby myself.Jerry's take on things from the start makes you feel calm and comfortable to sit right back and enjoy the ride.I give it a 5.Hands down so far,(only in the EFI Wiring chapter at the moment) good information and pure layman's terms to get you going on any choice of system/engine you may want to tinker with!Kudos to Jerry H./Matt C.,and everyone else @ DIYAutotune!!!!!!

This is an excellent primer on electronic fuel injection systems, their construction and operation. It covers a lot of the various aftermarket options' high and low points without being overly critical or gushing about any of them. If you are looking for a lot of specific information on tuning, this is not your book nor is it if you're expecting a lot of MegaSquirt information since Mr. Cramer is part of DIYAutoTune. This is more of an overall view, almost a textbook, and it's an excellent one. It will not teach you to tune your specific car, other than to explain the best way: pay for the dyno time and work it 'til it rocks. If you really want specific information about your system and/or combination in particular, join an online forum and start reading there.

Informative book

In the last 25years, I have pulled off some noteworthy engine and vehicle builds, including a Megasquirt II-Extra managed Eaton-supercharged Suzuki G16, and lately a MS3x turbo'd B16A1. Yes, all that knowledge of Holleys and Rochesters and Webers (oh my!) has been buried in dust and cobwebs since I discovered how to micromanage EFI. Cramer & Hoffmann (some of the most respected minds in the Megasquirt community) have shown me once again that there is more to learn - and more to be understood - on the topic. This book covers all types of systems, and to my surprise, they left very little room to discuss Megasquirt. Other standalone and OEM designs are used as examples instead, with deference and without bias, to educate the reader. Clearly written and full of useful illustration, this is the best book on the topic I've got- and I have a 6' bookshelf of automotive literature. Thank you guys for continuing my education!
