I received my smarty yesterday, and had trouble getting the smarty to talk to my ecm via the plug, I called bob and we talked while I was in the truck. The communication finally worked and I downloaded #9 and I just love the responce. This morning I tried to down load #1 and halfway thru, the down load aborted, I tried for 30 minutes and bad communications. I jumped in the wifes grocery getter and purchased some dielectric grease coated the drb connector on my truck, pluged and unluged smarty in a couple times, and it put the stock program into my truck and then I loaded #1 with no problem. I have all the confidence that my connection problems are cured. I could only guess what the cause was, which could have been armor all spray on the plastic in the vicitnity of the plug or anything. Just wanted to get this problem posted in case others have the same experience.
