I have a question about a dial switch. Take a look at the picture I have included. I recently bought an 87 Regal T. The original owner did quite a few modifications on the car. Unfortunately, he recently passed so I am not able to find out exactly what he did with the car. I know what the BscT box does. The question I have is about the little dial switch. It goes from 0 thru F. It is currently set at 1. What is the purpose of this dial switch ?
