I'll be happy to help them if I can.  I doubt they are interested my code because it is written in XML and their code is in C - and besides it appears they are trying to use the built-in FSX pressurization system whereas I just replaced it.

My advice would be to look into not ever using the "pressure dump" feature of FSX because it appears to be broken.  From what I saw in my testing, if that is removed the CS system should work.
