Try this one. I threw a VE table in there that should be close.
Flattened out the timing around idle. You had a bad dip (down to 15 deg?) about 1200 rpm.

Okay, got it saved and will try. Thanks for all the help. How did you get to these numbers on both spark and the ve?

Only got to try it at idle yesterday because of rain. At idle, it seemed do well. After it got warm I revved it a couple of good times and it didn't try and hunt for idle as it returned down. Will do more and report back as time and weather permits. How do you arrive at a good spark table? I see tables adjusted at idle and WOT; and some all across the board. How do you tune this table at areas other than idle and WOT?

From what I've read the best is to use a load bearing dyno and test at different RPM's for MBT. Not feasible for most of us as it would cost a fortune in dyno time.

Unfortunately, I don't have a dyno within miles and miles. Thanks for replying!

Glad to hear its working for you. Now use your histograms to further adjust the VE table.
As for how you arrive at a certain spark table, its all just from experience, and understanding what certain changes do.

Thanks for all the help. I would eventually like to be able gain the experience to do this. Just takes time and practice I'm sure.
