Things have been a little crazy here in the aftermath of hurricane Charley, once I can get the Viper out of the garage I will take a few pics of the nitrous system. With regard to system and the programing, I will let Larry answer that. The system works off an activation switch and a throttle position switch. The idea was to keep the system simple and affective. Many people go through the VEC2 and Larry has and can set it up this way, but then you have to change cards between nitrous and non nitrous runs. I have a lot of flexability with the way the system is setup now.
