Got my eprom programmer today and did not think to get an eraser......

Ripped the ACHT bin I am running and found that the "Initial Advance" is 10 degrees.

I was kind of hoping that it would be 0 degrees because that would have explained the seemingly large amount of pinging during the 3-4 gear area of acceleration when I had the distributor timing at 10 degrees.

I backed the timing down to 6 degrees and still have very light pinging in that area and now am not sure why since I now know what the Initial Advance is set to in the eprom.

hmmmmmmm....

What to do next?
