Anyway, the good stuff. Starts up warm relatively easily (didn't get a cold start as I'd run with the stock WUR in place while fooling with RPM).

But, it starts up with a very low lumpy idle with control pressure high off the scale and eWUR injector duty cycle solid at 90. Possibly some heat soak and needs to bleed off pressure? But the engine was not that hot, oil temp 60-70c.

Suddenly after a few seconds control pressure swings into the middle of the range and idle goes up to around 1,200. But its hunting badly and the hunting is in time with control pressure swinging and eWUR duty cycle swinging from peg to peg. See the video and log below. CP is lower left, CP duty cycle lower right. I provided video for the sound, I'm not touching anything when the idle suddenly changes.
