Can the IAT spark advance correction be safely reduced or zeroed out on a N/A engine?
Can the IAT spark advance correction be safely reduced or zeroed out on a N/A engine?
Reduced, yes. I don't let it pull timing until over 100 degree intake temps. That is where I start at 1 degree and 2-3 degrees by 113+.

If you don't post your tune and logs when you have questions you aren't helping yourself.
Hotter air is more detonation-prone than cooler air, and that doesn't change whether N/A or boosted.
If it's reduced too much. will the knock sensors step in and save it from detonation?
You are searching for an answer that'll give you permission to zero out the table, so I suspect you'll go ahead and do it anyway.
Control your air temps. Don't Bubba it.
*maybe* you can reduce some spots in this.. But this is going to hurt you in the long run. It needs to pull timing for hotter IAT's.
This table has to be completely redone with forced induction. I assume this isn't your case..

Does this modified table look acceptable?
Yeah

So i had this table zero'd up till about 60deg IAT at the drags, running octane booster as i wanted timing steady despite hot lapping it. Then i forgot to return it to stock and have had pinging issues on regular fuel. You can zero it but be cautious.
