At idle at IAC is at 49-51 mostly right on 50 but the Advance is ( from what efi is showing ) is bouncing around. But when I use the EFILives Control Panel and forced the IAC to 50 and try to see what RPM is was sitting at.

So what is EFI doing that when the IAC is forced, the timing sat at 21.5, but when running at 50 normally its bouncing all over?
From what I see, setting my Idle RPMs at 830 or 835 looks to be the best.

MAF Raw, IAC, ADV, MAF, RPM, gms/cyl using ( 15* MAF/RPM rounded up to 2 decimal places)
