ingition timing with map

I am looking at my datalog for my ls turbo and I am wondering why my spark advance doesnt match what is set in my controller? First wot pull spark advance drops to 13.5 at 160 kpa (should be 18). Second WOT pull spark advance is 17.7 (160 kpa), then I shift, still at WOT but spark advance drops to 13 (still at 160 kpa). My spark advance table is set for 13 degree over 200kpa. I am not sure why this is happening, any suggestion.

Thanks,
Josh

Look under Extended tab and mat based timing retard. Your iat's are high during the runs there and it's pulling timing for you

MAT-based Timing Retard, in "Extended" tab
