I set up a misfire config that has every single misfire monitor PID whatever current PCM I'm tuning will offer me. Then I multiply all the misfire tables by 1.5 until I get the computer OK with the cam being there, even at idle.
I know that make take a few more minutes to do but I've seen a lot of dead holes during compression checks on account of a misfire being driven / raced on too much and the driver had no idea it was that bad because the computer couldn't tell them.
