Have a AEM 30-0334 and always have issues adding it. I'll have it in my chamns list then all of a sudden next log it will be greyed out and when I go to add it again it's not even in the list. Can't use the external ones so have to use the ecu specific WB pid and when it works it works but I just tried for 10 min to add it again and it's not even in the list, the whole list is just gone. So irritating, did 2 WOT runs last night come to find out my WB pid magically vanished again
