The issue is that the VVT angle bounces back and forth between ~295* and ~270*. I'm pretty sure the cam isn't moving 20* since the car idles and runs perfectly. A composite log seems to confirm this. I worked out that at 1,000RPM 20* is about 3ms. I don't see 3ms of jitter anywhere in the log, but this is the first time I've really dug into one. Unplugging the solenoid has no affect on the numbers bouncing around. If I set the duty cycle to 100 the car stalls as expected. If I enable PID control the car surges badly while the cam tries to move to compensate for non-existant movement then eventually stalls. At the very end of the attached log I stall the car by advancing the cam and you can see a brief interval where the angle is >300*.
So far I tried to change from rising edge triggers to falling edge triggers as I saw other 99+ Miatas set up with falling edge. Couldn't get the car to start, sounded like it was very badly timed. Popping through the intake, kicking back the starter, etc and it didn't seem to have a good sync either. I also converted my cam signal to come in through the MS3X instead of onto the V3 board, made no difference once I got the VR trimpots adjusted. My sensor is a hall sensor though, could this be causing grief?
At a bit of a loss as to what the issue could be. Since this log and MSQ were taken I have upgraded my MS3 to 1.1 Alpha 18 and the issue is unchanged.
Attached below are my MSQ and a log where the picture above was taken from along with a composite log from today.
