These are not perfectly aligned, but the 3 below each line just continue after the prior line...hope you follow and the load / rpm follow the same format.

These turned out much better that I expected. Perhaps someone else could post their on a more aggressive timing curve to give me an idea what to do. I'll keep my fingers crossed.

How did you get those numbers? reading the PROM? That curve doesn't look all that bad to me.

You'll need some diag software with a capture mode to get much better without hurting the engine.
