i personally wouldn't tune for knock, the power should be a bell curve so as you hone in on the best settings power should rise then fall after maximum power is reached, then start to drop off before it knocks.

so that is what i'd tune for. at worst knock tuning would be a disaster on some engines, and on others you're likely loosing power . at the dyno i've often seen people say tune to knock then back off a whatever a good number/% they've heard is.

you have to know a lot of about the math of specific engine you're tuning for to do proper calcs to get you base maps that are close, so since not all that is available, VE being the most useful, it often does become iterative and you just get a feel for it.

dynos aren't that complex, they just measure torque. the manual for them usually has the operation procedure in them, or the rep shows you. but basically you just do a pull on it while it measures rpm/tq and AFR then it plots an HP/TQ graph usually with some compensation for loss, or which conversion factor to use, SAE etc (where a lot of the online battles take place on dyno figures)

i prefer dynapak's myself, mostly since theyre a lot safer and i don't walk over the roller when concentrating on the laptop, and i've felt they're more controllable/repeatable but YMMV

I highly recommend this book. Engine Management: Advanced Tuning https://www.amazon.com/dp/1932494421/ref=cm_sw_r_cp_apa_i_Tms.AbSAJMG09
It starts from the basics and then gets fairly complex so I feel it covers anything a new tuner would need. It describes the science behind what is happening so I guarantee you will find things in here you will use in the design presentation. It includes graphs and examples. Take notes as you go. The book covers the main forms of tuning an engine. MAF, alpha-n, and speed density. Realize that even though some things are described with MAF or turbos in mind, you can apply it to the other forms. Be able to tell your judge why you chose your strategy and how you executed it. The book is laid out really well and the later chapters describe how to go about tuning after all the terms have been described. 10/10, 11/10 w/ ethanol.

You want this book. Be aware that the concepts are math heavy.

This book may also be helpful, I've never read that one so I can't say.

The guy who wrote the first book - Greg Banish - was a tuner for several manufacturers and taught a tuning class/seminar for a while.

u/SavageTaco · 2 pointsr/mitsubishi

I originally tried the same thing (googling everything) but trying to find all the information I was looking for in one place was next to impossible. Plus you have so many contradicting views on how to go about tuning...etc.

Engine Management: Advanced Tuning by Greg banish. Its a little older (written in 2007) but still covers all the basics you will need.

Automotive engine management systems by Jeff Heartman. This book came out in 2013 (i believe) and deals a lot with volumetric efficiency (VE) based engine management systems (like the AEM infinity). This book was the first one I read and it really gives you a good understanding of things. Its much longer then the book above, but seeing as how it goes into greater depth and more aspects of tuning its worth the read.

Other honourable mentions:

Maximum boost by Corky bell (the book is a bit older, but its really well written and interesting)

"How to build" Max-Performance Mitsubishi 4G63 engines, by Robert Bowen (and Robert Garcia of Road Race Engineering RRE)

Engine Airflow by Harold Bettes

It sounds like you're comfortable with a carb; if that's the case then EFI should be easy for you. Greg Banish has a few books, this one and this one, that lay it out very well. These are the best how to books on the topic I know of. An Innovate LC2 (or the outgoing LC1 for a bit cheaper) is all the equipment you'll need.

I used to say the same thing about EFI vs carbs... now I can hardly imagine running a carbed car. My '83 Alfa will definitely get EFI, probably the '72 Duster as well. Part of that may be that I'm an engineer in the engine industry, I confess that I probably have certain biases.

I've used one on a custom car we made in high school. It was (relatively) easy to fiddle with if you know what you're doing. If you want anything custom(sequential injection or coil on plug ignition), you're going to have to know how to solder. It's pretty good for turbo applications (IMO) because they have a pretty good boost control solenoid for relatively cheep that's easy to install and a built-in MAP sensor. A megasquirt is what I'm going to get when I do my KA-T build. They're also pretty expandable if you want to change anything later.

If you do decide to go the megasquirt route, I would suggest reading a book like this or this so you really know what in the hell you're doing when it comes time to "mess with the tables". It was pretty challenging on that custom car.

Also, Porsche is awesome.

Many referred me to this 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?

u/theultimatehero2 · 1 pointr/cars

I tend to think the same way you do. Don't know where to start, just wish I could have someone explain everything and let me ask questions. While I'm sure that exists in the sense that there might be some expert out there willing to sit down and teach it, but what you're asking for is a course and instruction. Again, I'm sure that exists and it will cost money, I don't know where to start with that.

Otherwise it is completely up to you. Start scouring the internet, look through build threads and tuning forums, and read books on the subject. I just finished this one and I think it is a pretty good place to start if you need the basics on turbos. After that I'm moving on to this one to learn more about tuning. Just like most things in life, there is no easy button. If you want to learn it you have to do it yourself.

Did you just make this up or did you read that in a book like I did in addition to engine calibration experience.

Edit: Actual book I am referring to
