It's normal for settings to be lost during coding but return after. If it is a recurrent loss on subsequent start ups without the adapter plugged in or a permanent loss then it doesn't sound quite right. May be email the developer to let him know?
I have found it only loses the presets when I leave the adapter installed. I left it plugged in to access the exhaust flap opening.
I will buy a separate exhaust valve flap device.
Thanks,
Tom
