Could someone, preferably with and automatic, post a picture of their spark advance table? I'd like ot compare with mine.

Tuner Studio does generation of the VE table, not the spark advance. They have on-line advice on how to start a base line though.

The following link explains the basic theory behind creating a base-line spark advance table; and with some inputs from the user can generate one for you. Spark advance isn't a dark shrouded mystery.
The baseline it can create for you, if you enter the DeLorean engine properties correctly, will come eerily close to match the description of the spark advance curve found in the workshop manual.

Maybe I'm using a different version, but once I entered all my engine info along with where my timing would be at idle, TS had generated a usable ignition table for me when I opened the table window.

I have used the AFR and VE table generator before - just to see what it would come up with. The result was pretty bad. So even if there is an ignition table generator, I wouldn't have much faith in it.

There is a tremendous amount of engine tuning theory; including what AFRs are good for what load/rpm ranges for which kind of engines, what kind of ignition advances are good for load/rpm ranges, etc, all sitting out there.
Josh and I learned from doing A LOT of reading on in-depth engine theory, all from free articles through google. Stay away from learning on kiddie tuner sites, and pay attention to engineering documents, articles by established tuner shops, etc.
The AFR/VE table generators in Tuner Studio are garbage. The following is my AFR table, which is pretty much what 99% of naturally aspirated engines are going to look like. Of course, the underlying VE will vary, but the AFR target ranges are almost always identical.

For sake of comparision, here is my AFR table. This table is a result of constant tweaking over 13000mi

Mine is more aggressive as I leaned it out in the cruise sections for better mpg on the highway. I do not recommend this to a beginner. But it just goes to show there is no one "correct" or "perfect" tune. It is what you want it to be. That is where properly understanding the concept comes in. This comes from a lot of research!
