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

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.

Informative book

This book lay down the basics of EFI and covers a lot of the pitfalls a novice like me would stumble upon. If you just want to know how EFI works of pure interest or if you are planning a conversion of a carburettor engine to EFI, this is the one not to miss. It explains how the engine produce power from the fuel, how the EFI meets these needs and how to tune the engine for both maximum performance, maximum environmentally friendliness and maximum fuel efficiency in a clear pecise way that anybody can understand if they follow the text. The practical angle of the book keep the text readable and the sidebars gives your inner neard brain food.

I bought several other EFI books before I built my MegaSquirt kit from DIYAutoTune (the author's store) and they did a reasonable job explaining how things works and how to tune your new EFI system but spent a lot of time and effort on the mathematical aspects. While it helps to know some of the equations they spent many pages on all of them that I just ended skipping over. This book took a different, more practical approach. They explained the couple equations you had to know and put the rest in an appendix you could look at if you were interested. I found the discussion on proper wiring very helpful which might explain a couple of the issues I'm having with my system. The book is laid out in a very logical format with an appropriate number of pictures and illustrations. The only thing I was a little disappointed in was that I had been hoping they would spend a lot more time on MegaSquirt specific topics given that is what they sell in their store but of course that would have limited the market for the book quite a bit. They did spend some time on the MS (and that is what they used in their case studies at the end) but also discussed a number of other available systems. All in all I would say if I was starting over and could only buy one book on EFI, then it would be this one.

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!!!!!!

Excellent book very well written and full of interesting information Recomend to anybody thinking of mapping their own engine or to anybody just interested in the subject!

Fantastic explanation of your options for Engine Management either in a performance car or a modern engine in a classic.

I like to tune engines and this book did help alittle. But they still don't reveal how to properly tune efi systems. Dam reptile people holding all the tuning secrets.

Un trattato documentaristico che vi darà una infarinatura a livello molto leggero sull’elettronica legata al motore a combustione. Non ci troverete soluzioni concrete ma solo consigli fai da te.

No explica nada de otro mundo, en lo referente a Ecus y mapeado es simplemente una introducción. Está entretenido pero para un nivel medio no aporta nada
