stock lt1 getting spark knock
This isn't a third gen question but you guys are the most helpful people on the internet. The car is my 1994 z28 and while datalogging to solve another problem it showed I was getting 45+ degrees of timing which caused it to knock and pull a bunch of timing. Everything on it is stock except a catback and cai so the tune should be too. I'm using tunerpro rt incase anyone wants to see the log.

I'll guess the cause of both of my problems is the maf because it runs bad in open loop to which I think relies on maf readings. II'll check for vacuum leaks too though.
