Viper remote start issues

I've had a Viper alarm system on my Jeep for a few years and haven't had any problems with it except for the remote start. It will work fine if it has been running and is still warm. If it is cold, it will not start. It will try to turn over, but will never start. I asked a Best Buy installer about it and he said the RPM level needed to be adjusted to give it more time to start.

I've tried searching for this but can't find anything about setting this. Does anyone know how to do it/what he was talking about?
