I've been doing some data logging with datamaster. As I'm driving I get periodic transmission data errors in the top right hand corner.
Today my buddy tried to hook up MODIS and was not able to communicate with the computer. It is a 7730. Anybody got any ideas. I'm able to collect the data with datamaster, just the annoying noises on the computer when there is a data transmission error. Now I'm wondering if they are beng caused by the same problem? Bad ecm?? Bad ground?? Any thoughts?

Thanks
