to answer my own post, datalink protocol F2 must be ON. I also had the problem where i had the compustar unit in tachless mode and the vehicle would shut dowm ofter a few seconds running, once i switched the RS to wired tach mode and programmed the tach, all was well.

thanks to tech support for the info they provided on the phone!
