10/10 call from service advisor: Subaru field tech flashed ecu. Shop forman is going to drive car for a few days to monitor cel/idle issue. I can call Friday am to see if car is ready for me to take home.
Also as per tsb for crickets: will be correcting this as well as the chirping was rampant and not a figment of my imagination, or a "cute characteristic" as I last called it.
