I may be on to something, working getting logs for this, but it doesn't see to agree with your above statement.

2 hours later than the previous starts I went and restarted the car. This time I was getting the wild swings in eWUR duty cycle and control pressure. This was definitely resulting in pulsing in RPM and the stock needle going up and down. It exhibited all the symptoms of before, it was much worse at idle/in overrun, loading up would dampen it out some, but it would return when going back on idle.

All the parameters were exactly the same as before, nothing had been changed or adjusted either in the MS or with the engine. Engine temp was the same, target CP the same, mid-range on the RPM, eWUR d/c, CP the same. The only thing that was different was that my AFR was for some reason up around 15.6. I have no idea why, nothing should have changed. There was minimal/no pulsing in the FV d/c, which was sitting roughly at 50%.

If the AFR was the only thing different, and in dual table mode only the FV is used to target AFR, why was CP and eWUR d/c bouncing all over the place?

I will set the min eWUR d/c to 30 and the max to 95% and see if I can duplicate everything with logs.
