timing dip at first throttle
I was doing some logging to look for detonation and noticed something funny. My timing takes a drastic dip when I first apply throttle off idle. Attached is a graph showing it. I only apply about 7% throttle and my timing dips to 2.25 on both cylinders. At the MAP and RPM shown in the graph, my timing should be around 21. Has anyone else seen this?

I think I've figured it out. The MAP is spiking but the data log is not catching it due to only getting 5 samples per second. So the timing dip is coming from the high map low rpm area of my map.
