I found a similar thread on the msextra forum. It seems that a there is a known bug in the program that creates the error I am seeing when I try to activate the extra ports. It causes a conflict with the injector ports. I have asked if there has been any resolution to that but so far have gotten no response. I guess I am going to have to just go old-school and put a switched relay on the fans or something so they cut off when I turn off the engine.

Huh. Interesting. I'm assuming we still have the latest firmware loaded, you might want to contact Matt at DIY with a call or email and ask him about that. Could be a more direct route to a solution. If you do, try to give him the reference to where you found it.
