Also just looked again.. Dropping into and out of closed loop.
You can uncheck any of the traces on the log.
Try to deactivate some and look at only rpm, the closed loop, afr commanded and actual.
I'm wondering if the alky system is being sucked dry and messing with the afr.
Is it using a lot of alky?
Maybe turn the boost down, kill the alky, and see if AFR commanded and actual are close.
