Update. More data logging. It seems that one of the cams oscillates more than the other. This is most noticeable at idle. The set point is 0. The "good cam" stays pretty close, within about 0.4 degrees. However, the "bad cam" oscillates between -0.6 and 0.6. Watching the OCV duty it seems that when it gets to -0.6 the duty will increase slightly to bring it back to 0. But then it overshoots a little and hits 0.6. Thus the dugy cycle drops to bring it back to 0. But it overshoots a little and hits -0.6...and so on. It seems just a little sluggish. As mentioned I have swapped ocv's from one side to the other, so I doubt it is that. Any ideas on other bottlenecks that could be causing this "slow" response and oscillation?
