Guys,
I have been having a problem with cold start issues, the car runs well at 40d of timing or a little more/less at cruise. Well when I initially start the car it is a little ruff but not bad. But as soon as I put some load on it while driving it only reads about 20d of timing, give or take a few d. Is the above table the one used to adjust this problem?
I can actually watch diacom and after X amount of seconds it kicks out of "the routine" and bumps the D back up to 40+ and it runs great in open loop.
I've tried adding 10+ d to the startup spark advance with no ill effect.. Very odd.

there is a cold engine spark bias.
Rarely do you need to play with that.

Often the cold start stuff is too lean and that bumps the antistall code, and things look real confusing on a scanner.

I'd first try a little richer in cold start, and see if that doesn't help most

 

When I'm seeing the 20d of timing, I'm actually reading 900+ mv on the O2, it seems pretty rich to me.
