Breck,
That is strange that you have a problem with your EZ in cold weather. I had an EZ for two winters here in AK and used it all winter with NO problems at all. I now have a Drag Comp and run it all the time in the winter, also with no problems. I have run both boxes when the temps are into neg. numbers... hmmm There are several memebers of our Alaska club that have EZ's and don't have any problems. Funny it has not poped up here too.
Maybe it has to do with one of the many reflashes or is just particular to a certain year or model (ie auto/sticK) of truck. Who did you talk to at Edge?? I think I would call and talk to Aaron, he has always taken good care of me.
