Thank you RemoveBeforeFlight. After digging further into the logs, I noticed that it started at 22*BTDC before pulling timing. Now, in the BST-SA table, I have timing set for 18-19 in that area. After further looking, I notice the CTS/IAT offset table, and I think at that temp, 73C, it is adding timing. I have a 160 stat, so the engine will always run around 160-180. The hottest it got Wednesday after 1 hour driving was 183. I may need to make some adjustments to that table.
Also, could the really rich AFR cause some knock? I've never really known it to do that, but...
Thanks again! I'll make changes to the tables tonight, and will try and drive the car again tomorrow to work.
