wow thanks for the diagram Mr. Beer
at this point I'm trying to clairify the center pin connection for the v1 efi live. The EFI LC1 instructions say a signal ground is the green and white.
so do they mean the blue and white "system ground"?
Blue green and white are the grounds.
From the LC-1 manual
The BLUE and WHITE wires should all be grounded to the same ground source.
Although my diagram does not reflect that, they are in fact soldered together and grounded to the same spot, the green wire I grounded at different location.

Yes, with persistance, most can sort things out and make EFILive work for their applications. I've had EFILive as a scanner before there was a tuning package and it has met my needs very well although I'm still learning. It can't be said enough, read all of the documentation. That includes any other relevant documents. Also open a tuning file and familiarize yourself with the tuning catagories and PID definitions.
However, the term "learning curve" is somewhat of a misnomer. What I found frustrating was not the learning but the collecting of all the bits a pieces of information scattered all over the place. But what it is, is what it is.
The last criticism I would make has to do with the PCM operating system or more correctly the knowledge base of how it works. The is not a slam of those that worked long and hard to understand it, but of those that are sitting on the editor/compiler for Modulo II which I understand was the development software that GM used. The majority of the information was obtained by trial and error. Empirical data has limitations as shown in comments such as: I think so, I'm pretty sure, maybe. My confidence level gets lowered somewhat when I hear things like that. I wan't to say again don't take this as a strong criticism of the current knowledge base but it would certainly be a better way to have flow charts directly linked to the reverse engineering of GM's operating system. I've never seen anything in the public domain or even a little help in resolving some issues. I'm not a programmer nor do I wan't to be but I certainly would like to look at the source code. One additional comment Modulo II, I understand, is very simular to an old software called Pascal.
I didn't know these things before I started to get interested in doing my own tuning and maybe they will help others that are on the line.
Thanks

I don't have a green wire. That's what's confusing me.

Is it logical to assume that because I do not have a green wire but do have a white wire That the middle pin just goes with the white wire ground?
One set of instructions say connect it to the white and green (which I dont have). But I do have a white (system ground) and blue (heater ground) wire which are supposed grounded together.
Therefore it is logical to wire the middle to the white wire's ground.
And I will ground the black calibration wire else where.
Which is what I'm going to do now.
Agreed with the quilted together information gathering is TEDIOUS. It seems like rather than offering a "System" approach that is easy to hook up and learn, it is more of a badge of honor to blutten your way through.
I would further add the material available looks a bit dated and that may be why it seems to conflict between various sets of instructions. Thus far the innovative instructions have been the most accurate.
Is EFI live on the same path as ls1 edit and that's why everyone seems to be going to a more relivent and user friendly HP tuners?

Are you using the innovate instruction set?

yes those are the instructions I used and find most relivent to the wires and colors of the LC-1. I think I got the middle pin out is to the system ground reguardless of color.
Why not just call it the ground. Black goes to ground, blue goes to ground and white goes to ground. Green goes to ground to if you got one. The only one on a different ground would be the black calibration wire, though I don't nesc read that anywhere.
On beer's diagram, I see the white wire grounds out independantly of the ground bus, or it appears that way.
The one variation I used was the EFI instructions recommended yellow to the analogue in on the EFI live tool and the brown wire to the gauge.
is that right?
