I just installed the Compustar and it has a turbo timer for manual trans. the viper does not. The Compustar also has very long range. From what I could tell it has the longest available now. So far it has been a good alarm. Not to many alarms will let you remote start a manual transmission, this alarm was designed for them. I am impressed so far. www.compustar.org
Check the wires for your unlock.
There's two wires that need to be connected for unlock
Green/Red and Blue/White. Both are nagative trigger and need to be diode isolated before being connected to the Compustar.
