IIRC the LV8 value is a function of RPM and some other parameters to represent relative load of the engine. So for example if you are at 2000 RPM and at WOT, in the Main Spark Table, the value in the table at the intersection of 2000 RPM and 208 LV8 is your spark advance look-up that the ECM uses.
Conversely, if you are at 2000 RPM and coasting, your scan tool will probably show and LV8 of 32 or 48, and the value at that intersection is the spark advance look-up.
In my stock spark advance table the former is 26.02 degrees and the latter is 48.16 degrees advance.
Make sense? LV8 is used in many tables, think of it as a scale of engine load from idle to wide open throttle, it changes if you are going up a hill or down a hill, cruising, accelerating, decelerating, etc.
OK, got it, the LV8 (Spark Advance Table) is a static lookup with the columns representing a load calculated by other factors
I'm using WINBIN to view several different BIN files. Is there any documentation around to interpret what the various entires and values mean, and how they interact with each other ??
There's got to be some programming 'how do' for dummies document someplace.
I have never used WINBIN, I understand it is a pretty basic program. I use Turbo-link for my scanning and TunerPro for reading/editing. You can download the basic TunerPro for free, then all you need is the definition file for your ECM (.ECM file) and you're off and running reading your BIN (.bin files).
This should give you a pretty good view of what's in the chip without spending any money for TunerCat, etc. Check out motes.net and thirdgen.org for access to your ECM file and hundreds of BIN's.
