What is Reddit's opinion of Engine Management: Advanced Tuning?

From 3.5 billion Reddit comments

Many referred me to <strong>this</strong> book.

I have very little experience, but I have learned that you need to find out what your known values are (airflow, fuel pressure, timing) and adjust the fuel maps. Knowing exactly what your Air to Fuel ratio is a must. Once you have a target A/F ratio in mind, use your known parameters and adjust your fuel accordingly.

What is the output of your logs?

Not Subaru specific, but Greg Banish's Engine Management Advanced Tuning book is a great starting point. I would also recommend learning about engines (in general), Internal Combustion Engine Fundamentals is another staple to get started. You can find many online resources by searching for FSAE <topic&gt;, like FSAE Intake Manifold, or FSAE Exhaust.

well, honestly you can't learn everything you need to know about tuning on reddit. but here is what i would recommend

check out fitment industries, chris fix, and donut media they'll help you get started with the bare basics

when doing very complicated stuff it's better to let a professional do it, rather then trying it yourself. you will save yourself a lot of headaches.

start out with suspension, tires, and rims. when i say this i don't mean stance. I mean start researching it, most rally builds will use specific suspension kits that cost a upwards of $1500.

start reading books about tuning, research videos, take some online courses. this will help despite it being a slow process, you should fully grasp any tuning basics before starting your own build. seriously this is the most important step, and you should research EVERYTHING. this isn't an easy sport, and it's even harder to begin in. but it's better to at least dive in to it with as much knowledge as possible.

the reason that i put the most importance into knowledge is because i see way to many people start tuning/building with almost no knowledge. you can build whatever you want, but the way i see it is if you're asking on reddit, you already need to know more then you do right now.

also, patience isn't just key. it's everything. tuning isn't a week long process, you'd be lucky if you could get some of it done within a year. you'll find yourself eventually becoming a perfectionist, and never liking 1 thing for too long, so just understand that if you do commit to this, you're going to have to do this until it is done. and that takes a while.

here's what you need:

1. a lot of free time, or at least time in general
2. money, even the basic stuff like new tires can set you back a kidney
3. basic knowledge, you need to understand the basics of everything first
4. patience, ties in with time

here are some sources that helped me out (some aren't exactly them, but they're close as possible):

general engine tuning guide-book

engine blueprinting guide

a guide to fuel injection tuning

chris-fix's channel, for misc repairs and other stuff

motivation

so tl;dr: research, understand the basics, take it slow, understand that it's all about patience, have fun

that's all that i could think of at 2:00 am, but feel free to ask questions. again this wasn't a guide to tuning. but it was more of like a what you need to know before hopping in, reddit is probably the furthest place you should go to for advice on building a car.

These two books are a great place to start.

The first book goes over some of the basic stuff like what each sensor does and the overall process of tuning. The second book goes a bit more in-depth and discusses things like how to properly create your base fueling/efficiency map, why injector characterization is so important, why running E85 is beneficial in certain applications, etc.

Other than sitting in on dyno tuning sessions or asking questions to the engine lead, I found these two books one of the best sources of info.

I mostly learned on forums and such, but I did buy one book. Great starter resource

These are the two Banish books I'm most familiar with: Engine Management: Advanced Tuning, Designing and Tuning High Performance Fuel Injection Systems. They're pretty similar but the main difference is obvious from the title: the former is just tuning with a little bit of hardware and the second is about half and half hardware and tuning.

I try to remember that the RPi isn't really targeted at hobbyists, it's really an educational board. There are definitely better options if you're willing to give up the support and community. The Banana Pi is looking pretty good as well as the whole ODROID line. Since I'm not a coding guy I would probably be running a tuning PC program hence the requirement of x86.
