Here's what I did..

I had the car running with the exhaust valve open. Pulled the exhaust valve fuse, as identified in this post: (F203 in the trunk) https://www.supramkv.com/threads/exhaust-flap-always-open-with-engine-on.7591/post-119643

Car seems to work properly and valve is always open, regardless of engine "mode".

If you have a JB4 unit, press and hold the top button (car running and in park) on the blinker stalk until the blinker light flashes. It opens the valve a couple seconds after you start the car and makes your neighbors hate you in the mornings.
