You have something funky going on with your tune. In the last log it shows you at 180* with a commanded AFR of 12.53, but the tune shows you should be at 14.62. Duh. I have enclosed a new tune for you. I have adjusted the commanded AFR and hopefully this will help. Let me know what you come up with.
