Books that teach PCM tuning
you can't beat swept up food The people that know enough about our specific VCMs to write a book on it are probably either GM employees or members of this board.
A book would probably contain pretty general information because if it was specific enough to be useful the target audience would be too small to make it profitable to publish. The general information isn't extremely useful, and car/platform specific book would probably not sell enough copies to cover the cost of the publishing.
There is probably some published info out there on tuning stand alone systems, as they would have a larger market.
That being said, if you read enough about basic EFI, either Ben Straders book or others, and read the stickies and FAQs, that should pretty much get you up to speed with about everyone else.

is a post I made a few days ago where I tried to describe some of the basics...
One of these days when I have more time I'll have to put together a document with what I know (no where near everything, but I have a pretty good grasp of the basics
) Trending Topics
The Best V8 Stories One Small Block at Time

The trick is that to make the book appeal to a wide audience (GM guys, Ford Guys, Honda Guys, Aftermarket ECU guys, etc...) one needs to be a little more general in the explanations. The good thing is that almost all ECU's work on the same principle of creating a math model of the physical engine behavior. The ECU doesn't know if it's installed in a Civic or a Mustang, but it still figures out how much air mass is present and calculates a fuel mass, injection time, and spark lead accordingly.
To list the absolute step-by-step procedure for every ECU (including various years of the same engine/ECU) would make the book prohibitively large for publishers to print for a reasonable price. That's what the individual software user manuals are for. However, if one learns the general OEM calibration approach and applies it to whatever ECU they're tuning, things usually go much better. It's pretty easy to learn a new software if all you're really doing is learning what names they use to describe the same concept used on other engines you've learned about before.
As they say, "Watch this space..."
Although these books are not LS1/LS6 specific I've found them helpful in theory and practice.
They are not pro level but they have been very helpful at my level (amateur/tinkerer).

Hope these help some.
Whats the more important info in this book?

im reading it and its just telling me most of the stuff i already know. Its not really helping me with tuning so far.

Ok.....this is a decent reference book. Not a complete read through.........much isn't applicable to LSXs.
Chapter 1 Understanding Fuel Delivery - a nice overview.
Chapter 3 Sensors - decent review. My first read was Probst's "Corvette Fuel Injection" book and it provided an excellent description of the sensors and their use by the PCM.
Much on sensors and the PCM can be found in the Holden PDF. - in the Sticky section above. There is also a fair amount of info in the GM shop manuals.
Capter 8 Standalone Systems - vary basic - decent, succinct reference material.
Chapter 13 EMS Tuning 101 - I thought this was a concise, basic review of spark,air and fuel.
I still believe an excellent education in tuning can be gained by going to the LS1Tech PCM Diagnostics and Tuning Archive. Start at the beginning and read every post by NoGo. It's time consuming but the info and explanations are phenomenal. NoGo was amazing.

Here's the Archive -> start at page one....look for NoGo posts ->https://ls1tech.com/forums/ls1-domestic-forums/f-7.html
wasted $30's on it
