How About a Sticky or Thread Explaining the Purpose of Each Edit Table?
PE vs. RPM: The amount of fuel added on to the base fuel table under power enrichment situations versus RPM. To acheive desired air fuel ratio, take your current air fuel ratio and divide it by your desired ratio, then multiply the table by the resulting percentage for each area of RPM you need to change.
Then take the best explaination for eachtable and put them in a thread. What do you guys think? I know there are things that I'm not really sure what they exactly do, like CAT Test, count to pass. Hopefully the thread would end up putting everybody's knowledge together for a real LS1 Edit user's guide.
I think "Guru" is another term for 'CTRL-C, CTRL-V'.
I really like the "sticky" idea for the novice.

LS1edit is just a nice interface to the tables, they didn't choose how they're laid out or what their scale is, or any of that jazz. We're working with what GM designed into the box -- we just have the ability to change the numbers in the squares.That said, some tables can definitely be obscure as to their purpose. This isn't the fault of Carputing, because they didn't create them. This tool isn't the Macintosh of tuning. If you want that, get a product that hides the details from you (Hypertech, Diablo). With a more advanced tuning tool comes a (MUCH) higher learning curve. A lot of learning what each table does is learning how it relates to how the engine operates -- which isn't the fault of the tool or tool docs, really. Its kinda like asking for detailed instructions to be included in the package with a screwdriver so you can know how to tune a carburetor
Some of the things in there are very confusing, because of how GM wrote the underlying operating system code. What's worse is we don't have access to the original source code to look and see either. So while we may have the tables and data, nobody (save for the original coders @ GM) really knows 100% how they're interpreted and used. For example, the IAC running airflow and IAC park position tables. Changing values in either will directly affect idle -- so they're definitely related, but knowing exactly how is yet a mystery. Most folks simply scale them both up in unison and go about their business
Another area of speculation is the Secondary VE table. I've heard several conflicting opinions of when/how its actually used. People STILL argue about how/when the Main VE table is used (and yes, it DOES affect closed-loop fueling).So moving on, I FULLY support REAL-WORLD findings on what some of the more obscure tables have been found to do... I've spent countless numbers of hours in controlled "experiments" trying to figure some of them out, as have some other folks -- but that comes with the territory. Sure beats the tuning methods of yesteryear where I was hand hex-editing raw binary files and burning them back to a J3 adaptor EPROM for my Mustang
Worst case, I'd like to see a sticky thread at the top. Instead of trying to sticky every good informative thread, use it to post links to those threads. Have sections for IDLE, PE, TIMING, etc.. so its easy to sort through. That shouldn't take much effort. After people post a link to what they think is a good thread, an Admin / Mod could add it to the top post, and purge out all the replies.
Also rename the link to the thread to a more meaningful title. It seems that most of the good threads start out with a title like "car won't start after adjusting xxx"
