Anyway, I agree with Jody on most everything but a couple things to remember. I like a little IAC at idle when hot, sometimes it will decel a little better. With a cam that size the IAC isn't really stabilizing the idle anyway, your spark control is taking care of most of that.
Also your starting fuel will bleed over into your intitial running fueling, keep that in mind.
And if possible, turn the key on, let the O2 heat up and then try to fire it while checkng your air/fuels. Yes your fuel pump will cycle but it will restart the second it sees an ignition signal. That may help in directing as to which way to go. I agree, 42ms seems excessive.

the way I described has always ended up with some IAC at idle for me. I agree, you want a bit, just not half or more of your adjustment range being used up just to get it to idle when warmed up. And Accel was harder to tune for me than any other system I've tried (Gen VII anyway). Does not make it bad or not capable.
