I'm sorry but what you wrote is confusing, I don't understand it.
First you wrote that the antidive does not work at all at you. After you wrote a problem that the antidive switching on/off at the wrong places in your opinion.
I'm wondering how is it switching on/off at wrong places when it is not working at all at you?
Pleasee explain this to me, because I have no idea what and how you doing/testing thinks, I'm totally confused.
