I am getting an error when I connect my bitwriter to my Viper 791VX. I just installed the alarm and it works perfect. Now I want to program the alarm but I get the following error.
"not a valid system"
I have ver 1.4 in the bitwriter.
Any suggestions? Do I need to do something to the alarm to get it to communicate with the bitwriter?

ya, you need to upgrade the bitwriter to the newest version. I believe we are all on 1.6. Someone correct me if I am wrong. I barley use my bit writer

I was thinking of that, but the manual says that the 791XV needs version 1.4 or better. I will get the updated chip, thanks.
Does anyone know who in the Detroit area has the chips?
