Idle hunt
Idle hunt (1) My 2001 Z28 with a Yank SS3200 converter hunts for the proper idle rpm sometimes. I have it set at 600 rpm via HP Tuners.
What tuning can I do to prevent the occasional idle rpm hunt?
(2) Also I will be installing a 212/218 .522/.529 114 LSA cam soon. What tuning will be useful to do after this cam install?

If your RPM is 600, then it will be harder to get it to idle stable with all the various loads, ac, power steering etc.
Id suggest going into the 700's.
Idle and idle transition is one of the hardest things to get right, you need to identify exactly when it hunts. Check your RAF and timing in the idle cells. If your stock stoich at idle should be fine for fueling.
Have a play with the bidirectional controls for spark once your RAF is dialled in.
